|---|---|---|---|---|---|
| CVE-2020-28010 | 1 Exim | 1 Exim | 2026-06-17 | 7.2 HIGH | 7.8 HIGH |
| Exim 4 before 4.94.2 allows Out-of-bounds Write because the main function, while setuid root, copies the current working directory pathname into a buffer that is too small (on some common platforms). | |||||
| CVE-2020-28009 | 1 Exim | 1 Exim | 2026-06-17 | 7.2 HIGH | 7.8 HIGH |
| Exim 4 before 4.94.2 allows Integer Overflow to Buffer Overflow because get_stdinput allows unbounded reads that are accompanied by unbounded increases in a certain size variable. NOTE: exploitation may be impractical because of the execution time needed to overflow (multiple days). | |||||
| CVE-2020-28008 | 1 Exim | 1 Exim | 2026-06-17 | 7.2 HIGH | 7.8 HIGH |
| Exim 4 before 4.94.2 allows Execution with Unnecessary Privileges. Because Exim operates as root in the spool directory (owned by a non-root user), an attacker can write to a /var/spool/exim4/input spool header file, in which a crafted recipient address can indirectly lead to command execution. | |||||
| CVE-2020-28007 | 1 Exim | 1 Exim | 2026-06-17 | 7.2 HIGH | 7.8 HIGH |
| Exim 4 before 4.94.2 allows Execution with Unnecessary Privileges. Because Exim operates as root in the log directory (owned by a non-root user), a symlink or hard link attack allows overwriting critical root-owned files anywhere on the filesystem. | |||||
| CVE-2020-12783 | 4 Canonical, Debian, Exim and 1 more | 4 Ubuntu Linux, Debian Linux, Exim and 1 more | 2026-06-17 | 5.0 MEDIUM | 7.5 HIGH |

| CVE-2019-16928 | 4 Canonical, Debian, Exim and 1 more | 4 Ubuntu Linux, Debian Linux, Exim and 1 more | 2026-06-17 | 7.5 HIGH | 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-2019-15846 | 2 Debian, Exim | 2 Debian Linux, Exim | 2026-06-17 | 10.0 HIGH | 9.8 CRITICAL |
| Exim before 4.92.2 allows remote attackers to execute arbitrary code as root via a trailing backslash. | |||||
| CVE-2019-13917 | 2 Debian, Exim | 2 Debian Linux, Exim | 2026-06-17 | 10.0 HIGH | 9.8 CRITICAL |
| Exim 4.85 through 4.92 (fixed in 4.92.1) allows remote code execution as root in some unusual configurations that use the ${sort } expansion for items that can be controlled by an attacker (e.g., $local_part or $domain). | |||||
| CVE-2019-10149 | 3 Canonical, Debian, Exim | 3 Ubuntu Linux, Debian Linux, Exim | 2026-06-17 | 10.0 HIGH | 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. | |||||
| CVE-2018-6789 | 3 Canonical, Debian, Exim | 3 Ubuntu Linux, Debian Linux, Exim | 2026-06-17 | 7.5 HIGH | 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-2017-16944 | 2 Debian, Exim | 2 Debian Linux, Exim | 2026-06-17 | 5.0 MEDIUM | 7.5 HIGH |
| The receive_msg function in receive.c in the SMTP daemon in Exim 4.88 and 4.89 allows remote attackers to cause a denial of service (infinite loop and stack exhaustion) via vectors involving BDAT commands and an improper check for a '.' character signifying the end of the content, related to the bdat_getc function. | |||||
| CVE-2017-16943 | 2 Debian, Exim | 2 Debian Linux, Exim | 2026-06-17 | 7.5 HIGH | 9.8 CRITICAL |
| The receive_msg function in receive.c in the SMTP daemon in Exim 4.88 and 4.89 allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free) via vectors involving BDAT commands. | |||||
| CVE-2017-1000369 | 2 Debian, Exim | 2 Debian Linux, Exim | 2026-06-17 | 2.1 LOW | 4.0 MEDIUM |
| Exim supports the use of multiple "-p" command line arguments which are malloc()'ed and never free()'ed, used in conjunction with other issues allows attackers to cause arbitrary code execution. This affects exim version 4.89 and earlier. Please note that at this time upstream has released a patch (commit 65e061b76867a9ea7aeeb535341b790b90ae6c21), but it is not known if a new point release is available that addresses this issue at this time. | |||||
| CVE-2016-9963 | 3 Canonical, Debian, Exim | 3 Ubuntu Linux, Debian Linux, Exim | 2026-06-17 | 2.6 LOW | 5.9 MEDIUM |
| Exim before 4.87.1 might allow remote attackers to obtain the private DKIM signing key via vectors related to log files and bounce messages. | |||||
| CVE-2016-1531 | 1 Exim | 1 Exim | 2026-06-17 | 6.9 MEDIUM | 7.0 HIGH |
| Exim before 4.86.2, when installed setuid root, allows local users to gain privileges via the perl_startup argument. | |||||
| CVE-2014-2972 | 1 Exim | 1 Exim | 2026-06-17 | 4.6 MEDIUM | N/A |
| expand.c in Exim before 4.83 expands mathematical comparisons twice, which allows local users to gain privileges and execute arbitrary commands via a crafted lookup value. | |||||
| CVE-2014-2957 | 1 Exim | 1 Exim | 2026-06-17 | 6.8 MEDIUM | N/A |
| The dmarc_process function in dmarc.c in Exim before 4.82.1, when EXPERIMENTAL_DMARC is enabled, allows remote attackers to execute arbitrary code via the From header in an email, which is passed to the expand_string function. | |||||
| CVE-2012-5671 | 1 Exim | 1 Exim | 2026-06-16 | 6.8 MEDIUM | N/A |
| Heap-based buffer overflow in the dkim_exim_query_dns_txt function in dkim.c in Exim 4.70 through 4.80, when DKIM support is enabled and acl_smtp_connect and acl_smtp_rcpt are not set to "warn control = dkim_disable_verify," allows remote attackers to execute arbitrary code via an email from a malicious DNS server. | |||||
| CVE-2011-1764 | 1 Exim | 1 Exim | 2026-06-16 | 7.5 HIGH | N/A |
| Format string vulnerability in the dkim_exim_verify_finish function in src/dkim.c in Exim before 4.76 might allow remote attackers to execute arbitrary code or cause a denial of service (daemon crash) via format string specifiers in data used in DKIM logging, as demonstrated by an identity field containing a % (percent) character. | |||||
| CVE-2011-1407 | 1 Exim | 1 Exim | 2026-06-16 | 7.5 HIGH | N/A |
| The DKIM implementation in Exim 4.7x before 4.76 permits matching for DKIM identities to apply to lookup items, instead of only strings, which allows remote attackers to execute arbitrary code or access a filesystem via a crafted identity. | |||||
