CVSS v3.1 |
| Use of uninitialized resource in Remote Desktop Client allows an authorized attacker to execute code over a network. |
| A vulnerability was identified in Eleveo Call Recording Software 9.7.0. This vulnerability affects unknown code of the file /callrec/userAddAction.do of the component User Management. Such manipulation of the argument Username leads to ldap injection. The attack can be executed remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way. |
| LDAPCache and LDAPBackingEngine build LDAP search filters for user lookup and role lookup by textually substituting the placeholders %u, %dn, and %fqdn (drawn from the login name, the resolved user DN, and its fully qualified namespace form) into administrator-configured filter templates (userFilter, roleFilter). Before the fix, the only sanitization applied to the substituted value was double backslashed:
filter = filter.replaceAll(Pattern.quote("%u"), Matcher.quoteReplacement(user));
filter = filter.replace("\\", "\\\\");
This does not escape the other characters RFC 4515 requires escaping in an LDAP search filter: *, (, ), and NUL. A login name containing any of these can change the structure of the resulting filter rather than being matched as a literal value (e.g. a crafted username can turn an equality match into a wildcard match, or close/reopen filter clauses), widening what the search returns and potentially causing a login or role lookup to match an LDAP entry other than the intended one, over-granting roles, and depending on deployment-specific filter templates, potentially affecting which account a login resolved to.
It's not exploitable through every entry points: LDAPLoginModule and LDAPPubkeyLoginModule both called Util.doRFC2254Encoding() (correct RFC 4515 escaping) on the login name before handing it to LDAPCache, which masked the missing escaping in LDAPCache for those two call paths. Using LDAPCache directly (bypassing the login modules) does not reproduce through the normal LDAPLoginModule/LDAPPubkeyLoginModule authentication flow for this reason. It does reproduce through two other call paths that reach LDAPCache/LDAPBackingEngine without any prior escaping:
* GSSAPILdapLoginModule passes the NameCallback name straight through, unescaped.
* LDAPBackingEngine (listRoles) passes principal.getName() straight through, unescaped. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: client: avoid using uninitialized SIDs in cifs_posix_to_fattr()
cifs_posix_to_fattr() ignores the return value of posix_info_parse().
When a malformed POSIX directory entry is encountered (e.g. invalid
SID lengths from an untrusted server), posix_info_parse() returns -1
without populating the 'parsed' struct. The uninitialized stack
memory in parsed.owner and parsed.group is then passed to
sid_to_id(), which processes the garbage bytes and passes them to
request_key() to construct a SID string, potentially leaking kernel
stack contents to the userspace idmap daemon.
Fix this by checking the return value and skipping the SID-to-id
mapping when parsing fails. The remaining fattr fields (timestamps,
mode, etc.) are populated directly from the 'info' pointer so they
are unaffected. |
| RabbitMQ is a messaging and streaming broker. The advisory establishes affected 3.13, 4.0, 4.1, 4.2, and 4.3 maintenance lines but contains conflicting first-fixed versions for the 3.13, 4.0, and 4.1 lines. fill/2 substitutes ${username} into user_dn_pattern without RFC 4514 DN escaping, allowing a crafted username to alter the LDAP bind DN and potentially select a different directory entry. Exploitation requires rabbitmq_auth_backend_ldap with a user_dn_pattern containing ${username}, a directory layout in which the injected suffix resolves usefully, and a password valid for the resulting DN. The advisory body identifies 3.13.15, 4.0.20, 4.1.11, 4.2.9, and 4.3.3 as fixed, while structured metadata identifies 3.13.18, 4.0.23, 4.1.14, 4.2.9, and 4.3.3. No fixed-version assertion is certifiable until a curator resolves this conflict. |
| GLPI is a free asset and IT management software package. From 0.70 until 10.0.26 and 11.0.8, an authenticated hotliner or technician can submit crafted criteria through the user import feature to bypass the configured default LDAP filter. This allows access to LDAP objects that the default filter was intended to exclude. This issue is fixed in versions 11.0.8 and 10.0.26. |
| In the Linux kernel, the following vulnerability has been resolved:
smb/client: zero-initialize stack-allocated cifs_open_info_data
Stack-allocated cifs_open_info_data may contain random data.
This can make some fields have wrong value if they are not set later. |
| In the Linux kernel, the following vulnerability has been resolved:
nvme-fc: Do not cancel requests in io target before it is initialized
A new nvme-fc controller in CONNECTING state sees admin request timeout
schedules ctrl->ioerr_work to abort inflight requests. This ends up
calling __nvme_fc_abort_outstanding_ios() which aborts requests in both
admin and io tagsets. In case fc_ctrl->tag_set was not initialized we
see the warning below. This is because ctrl.queue_count is initialized
early in nvme_fc_alloc_ctrl().
nvme nvme0: NVME-FC{0}: starting error recovery Connectivity Loss
INFO: trying to register non-static key.
The code is fine but needs lockdep annotation, or maybe

| In the Linux kernel, the following vulnerability has been resolved:
hwmon: (ltc4282) Make sure clk_init_data is fully initialized
The clk_init_data structure contains several mutually-exclusive members
for different methods to specify the possible parents of a clock,
prompting drivers to initialize only the members they need. However,
not initializing all members may cause subtle issues, which are only
exposed when CONFIG_INIT_STACK_ALL_PATTERN or CONFIG_INIT_STACK_NONE is
enabled.
ltc428_clk_provider_setup() does not fill in any parent clocks, and
assumes that init.num_parents is NULL. However, the latter in
uninitialized, and thus may cause a crash.
Make sure all members are fully initialized, to fix such bugs, and to
avoid future breakage when converting drivers to a different method for
specifying the parents. |
| In the Linux kernel, the following vulnerability has been resolved:
hwmon: (asus_rog_ryujin) Validate HID report lengths
rog_ryujin_raw_event() parses response headers and payload fields without
first checking that they are present in the received report. A short report
can therefore make the driver consume uninitialized bytes from the HID
transport buffer and expose them as sensor values through sysfs.
Validate the response header and the fields used by each response type
before parsing them. |
| In the Linux kernel, the following vulnerability has been resolved:
bnxt_en: Handle buffer allocation failure in bnxt_rx_ring_reset()
bnxt_rx_ring_reset() frees the ring buffers and then reallocates them,
ignoring the result.
bnxt_alloc_one_rx_ring() can fail in bnxt_alloc_one_tpa_info_data(), which
returns -ENOMEM on the first failed allocation and leaves the remaining
rxr->rx_tpa[] entries zeroed.
The error isn't propagated up, so the loop in bnxt_rx_ring_reset
continues and at the end the code re-enables TPA with partially
unallocated rx_tpa array.
This means that when the agg_id from hardware is mapped to a SW index in
rxr->rx_tpa[], an uninitialized slot can be chosen which would hand a
zero DMA address to the device.
Fix this by falling back to a global reset, which is what the existing
code already does when other functions fail, but unlike the other
failure cases this particular failure has to return because TPA can't
be re-enabled since the allocation failed. |
| In the Linux kernel, the following vulnerability has been resolved:
xfs: initialise error in xfs_defer_finish_one()
xfs_defer_finish_one() declares error without an initialiser and only
assigns it inside the loop over dfp->dfp_work. When that list is empty
the loop body never runs, control falls through to the "Done with the
dfp, free it" path, and the function returns an indeterminate value.
An item-less pending item reaches this through xfs_defer_add_barrier(),
which xfs_reap_ag_blocks() uses on any CONFIG_XFS_ONLINE_REPAIR kernel.
xfs_defer_finish_noroll() treats any non-EAGAIN return as fatal, so a
non-zero stack value turns a successful barrier into a
SHUTDOWN_CORRUPT_INCORE in the middle of a repair. Zero is the correct
result: reaching the free path means the item loop drained without a
non-zero error. |
| In the Linux kernel, the following vulnerability has been resolved:
bnxt_en: Propagate TPA buffer allocation failures in bnxt_queue_mem_alloc()
bnxt_alloc_one_tpa_info_data() returns -ENOMEM as soon as one allocation
fails. This leaves the remaining rxr->rx_tpa[] entries zeroed.
bnxt_queue_mem_alloc() discards that return value, so the partially
initialized ring is installed by bnxt_queue_start().
Since the agg_id is picked by the hardware and bnxt_alloc_agg_idx maps
it to a SW index in rxr->rx_tpa[], it is possible that an uninitialized
slot can be chosen which would hand a zero DMA address to the device.
Fix this by checking the return value of bnxt_alloc_one_tpa_info_data
and unwinding, freeing the ring buffers. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs: treat any nonzero dio zero-range return as an error
ntfs_dio_zero_range() returns either 0 or a negative errno from
blkdev_issue_zeroout(); it never returns a positive value. The
zeroing failure check in ntfs_attr_fallocate() therefore never fired,
so a failed zeroing operation was silently ignored: the loop kept
going, the newly allocated clusters were folded into initialized_size
and the write could succeed leaving stale on-disk data.
Treat any nonzero return as an error and abort the allocation. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_core: Fix race condition during device registration
In hci_register_dev(), the power_on work item is queued to
hdev->req_workqueue before initializing hdev->adv_monitors_idr and
registering the MSFT extension via msft_register(). For devices marked with
quirks such as HCI_QUIRK_RAW_DEVICE, the HCI_UNCONFIGURED flag is set on
the device. When the power_on work item runs concurrently on another CPU,
hci_power_on() detects that the device is unconfigured and immediately
invokes hci_dev_do_close(), which calls msft_do_close().
Concurrently, msft_register() allocates the msft structure and exposes it
to hdev->msft_data prior to calling mutex_init(&msft->filter_lock). If
msft_do_close() executes while hdev->msft_data is already assigned but the
mutex has not yet been initialized, mutex_lock(&msft->filter_lock) operates
on an uninitialized mutex, triggering a DEBUG_LOCKS warning:
DEBUG_LOCKS_WARN_ON(lock->magic != lock)

Fix this by moving the queue_work() call in hci_register_dev() to after
idr_init(&hdev->adv_monitors_idr) and msft_register(hdev) so that device
structures and extensions are fully initialized before asynchronous tasks
can access them. Additionally, assign hdev->msft_data in msft_register()
only after mutex_init(&msft->filter_lock) has completed. |
| In the Linux kernel, the following vulnerability has been resolved:
ext4: fix circular lock dependency in ext4_ext_migrate
Move iput(tmp_inode) after ext4_writepages_up_write() to avoid a
circular lock dependency between s_writepages_rwsem and sb_internal
(freeze protection).
The deadlock scenario:
CPU0 (EXT4_IOC_MIGRATE) CPU1 (orphan cleanup during mount)
---- ----
ext4_ext_migrate()
ext4_writepages_down_write()
s_writepages_rwsem (write)
ext4_evict_inode()

...
ext4_writepages()
s_writepages_rwsem (read) [BLOCKED]
iput(tmp_inode)
ext4_evict_inode()
sb_start_intwrite() [BLOCKED]
The tmp_inode is a temporary inode with nlink=0 created solely for
building the extent tree. Its eviction does not require
s_writepages_rwsem protection, so deferring iput() until after
releasing the rwsem is safe. |
| The Okta Access Gateway does not sanitize SAML assertion attribute values before interpolating them into LDAP search filters in the LDAP datastore configuration. The raw values are substituted directly into the filter string and passed to the LDAP search operation, resulting in modification of the intended query logic. |
| A use-of-uninitialized memory vulnerability exists in libxls 1.6.3 when parsing malformed XLS files. The issue is reachable via xls_parseWorkBook() and is triggered by uninitialized heap memory originating from the OLE layer (ole2_read). The flaw is detectable with MemorySanitizer (MSAN) and can lead to undefined behavior, incorrect parsing logic, or potential information disclosure. |
| Imager versions before 1.036 for Perl disclose uninitialised heap memory reading a paletted image with pixel indexes past its colour map in i_gpix_p and i_glin_p.
The palette is allocated uninitialised, and only the entries a reader adds count as populated. The TGA reader stores pixel indexes without checking them against the colour map. i_gpix_p() rejects only an index greater than the count, so an index equal to it reads the first unpopulated entry, and getpixel() returns it.
i_glin_p() skips any index at or beyond the count without writing that pixel to the caller's buffer. The palette-to-RGB conversion reads each row through an uninitialised buffer, so those pixels of the converted image hold prior heap contents.
Reading an attacker-supplied image through Imager->read() and then fetching its pixels or converting it to RGB discloses process heap memory. |
| Use of uninitialized resource in Windows Spaceport.sys allows an authorized attacker to disclose information locally. |
