|---|---|---|---|---|
| CVE-2026-94055 | 1 Exim | 1 Exim | 2026-09-22 | 3.7 Low |
| Exim before 4.100.1, when certain non-default TLS settings are used with GnuTLS, has a use-after-free. | ||||
| CVE-2026-94054 | 1 Exim | 1 Exim | 2026-09-22 | 7 High |
| Exim before 4.100.1, when Proxy-Protocol is used with an attacker-controlled proxy, has an out-of-bounds write. | ||||
| CVE-2026-94057 | 1 Exim | 1 Exim | 2026-09-22 | 4 Medium |
| Exim before 4.100.1 allows SMTP smuggling in which the received message does not match any sent message, and instead depends on crafted data sent after a rejection during DATA processing. | ||||
| CVE-2026-94056 | 1 Exim | 1 Exim | 2026-09-21 | 7.5 High |
| Exim before 4.100.1, when Proxy-Protocol is used with an attacker-controlled proxy, allows attackers to read certain uninitialized data from stack memory. | ||||
| CVE-2026-66141 | 1 Exim | 1 Exim | 2026-08-03 | 7.4 High |
| Exim before 4.99.5 allows .forward privilege escalation because force_command for a pipe transport is mishandled. | ||||
| CVE-2026-66140 | 1 Exim | 1 Exim | 2026-07-26 | 8.4 High |
| Exim before 4.99.5 allows directory traversal to access files outside of the spool area, and consequently gain privileges, because arguments related to queue-name are mishandled. | ||||
| CVE-2026-45185 | 1 Exim | 1 Exim | 2026-06-18 | 9.8 Critical |
| Exim before 4.99.3, in certain GnuTLS configurations, has a remotely reachable use-after-free in the BDAT body parsing path. It is triggered when a client sends a TLS close_notify mid-body during a CHUNKING transfer, followed by a final cleartext byte on the same TCP connection. This can lead to heap corruption. An unauthenticated network attacker exploiting this vulnerability could execute arbitrary code. | ||||
| CVE-2026-48840 | 1 Exim | 1 Exim | 2026-06-05 | 5.3 Medium |
| Exim 4.88 before 4.99.4, in some proxy configurations, mishandles certain short payloads, leading to disclosure of uninitialized stack memory values to a client. | ||||
| CVE-2026-40685 | 1 Exim | 1 Exim | 2026-05-02 | 6.5 Medium |
| In Exim before 4.99.2, when JSON lookup is enabled, an out-of-bounds heap write can occur when a JSON operator encounters malformed JSON in an untrusted header, because of an incorrect implementation of \ skipping. | ||||
| CVE-2026-40684 | 1 Exim | 1 Exim | 2026-05-01 | 5.9 Medium |
| In Exim before 4.99.2, on systems using musl libc (not glibc), an attacker can crash the connection instance when malformed DNS data is present in PTR records. This is caused by a dn_expand oddity in octal printing. | ||||
| CVE-2026-40686 | 1 Exim | 1 Exim | 2026-05-01 | 3.7 Low |
| In Exim before 4.99.2, when utf8 operators are enabled, there is an out-of-bounds read if large UTF-8 trailing characters are present (malformed UTF-8 header data). Information might be divulged within an error message produced during handling of an unrelated e-mail message. | ||||
| CVE-2026-40687 | 1 Exim | 1 Exim | 2026-05-01 | 4.8 Medium |
| In Exim before 4.99.2, when the SPA authentication driver is used with an adversarial SPA resource, there can be an out-of-bounds write that crashes the connection instance, or erroneous data processing that divulges data from uninitialized heap memory. | ||||
| CVE-2010-4344 | 5 Canonical, Debian, Exim and 2 more | 6 Ubuntu Linux, Debian Linux, Exim and 3 more | 2026-04-21 | 9.8 Critical |
| Heap-based buffer overflow in the string_vformat function in string.c in Exim before 4.70 allows remote attackers to execute arbitrary code via an SMTP session that includes two MAIL commands in conjunction with a large message containing crafted headers, leading to improper rejection logging. | ||||
| CVE-2010-4345 | 5 Canonical, Debian, Exim and 2 more | 5 Ubuntu Linux, Debian Linux, Exim and 2 more | 2026-04-21 | 7.8 High |
| Exim 4.72 and earlier allows local users to gain privileges by leveraging the ability of the exim user account to specify an alternate configuration file with a directive that contains arbitrary commands, as demonstrated by the spool_directory directive. | ||||
| CVE-2025-53881 | 2 Exim, Opensuse | 2 Exim, Tumbleweed | 2026-04-15 | N/A |
| A UNIX Symbolic Link (Symlink) Following vulnerability in logrotate config in the exim package allowed privilege escalation from mail user/group to root.This issue affects Tumbleweed: from ? before 4.98.2-lp156.248.1. | ||||
| CVE-2025-67896 | 1 Exim | 1 Exim | 2025-12-22 | 7 High |
| Exim before 4.99.1, with certain non-default rate-limit configurations, allows a remote heap-based buffer overflow because database records are cast directly to internal structures without validation. | ||||
| CVE-2025-26794 | 1 Exim | 1 Exim | 2025-12-18 | 7.5 High |
| Exim 4.98 before 4.98.1, when SQLite hints and ETRN serialization are used, allows remote SQL injection. (Resolving SQL injection requires an update to 4.99.1 in certain non-default rate-limit configurations.) | ||||
| CVE-2019-16928 | 4 Canonical, Debian, Exim and 1 more | 4 Ubuntu Linux, Debian Linux, Exim and 1 more | 2025-11-07 | 9.8 Critical |
| Exim 4.92 through 4.92.2 allows remote code execution, a different vulnerability than CVE-2019-15846. There is a heap-based buffer overflow in string_vformat in string.c involving a long EHLO command. | ||||
| CVE-2018-6789 | 3 Canonical, Debian, Exim | 3 Ubuntu Linux, Debian Linux, Exim | 2025-11-07 | 9.8 Critical |
| An issue was discovered in the base64d function in the SMTP listener in Exim before 4.90.1. By sending a handcrafted message, a buffer overflow may happen. This can be used to execute code remotely. | ||||
| CVE-2019-10149 | 3 Canonical, Debian, Exim | 3 Ubuntu Linux, Debian Linux, Exim | 2025-11-06 | 9.8 Critical |
| A flaw was found in Exim versions 4.87 to 4.91 (inclusive). Improper validation of recipient address in deliver_message() function in /src/deliver.c may lead to remote command execution. | ||||
