| CVE-2023-42118 | 2 Exim, Libspf2 Project | 3 Exim, Libspf2, Libspf2 | 2025-08-07 | 8.8 High |
| Exim libspf2 Integer Underflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Exim libspf2. Authentication is not required to exploit this vulnerability. The specific flaw exists within the parsing of SPF macros. When parsing SPF macros, the process does not properly validate user-supplied data, which can result in an integer underflow before writing to memory. An attacker can leverage this vulnerability to execute code in the context of the service account. . Was ZDI-CAN-17578. | ||||
| CVE-2023-42115 | 1 Exim | 1 Exim | 2025-08-07 | 9.8 Critical |
| Exim AUTH Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Exim. Authentication is not required to exploit this vulnerability. The specific flaw exists within the smtp service, which listens on TCP port 25 by default. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of a buffer. An attacker can leverage this vulnerability to execute code in the context of the service account. . Was ZDI-CAN-17434. | ||||
| CVE-2024-39929 | 1 Exim | 1 Exim | 2025-07-10 | 5.4 Medium |
| Exim through 4.97.1 misparses a multiline RFC 2231 header filename, and thus remote attackers can bypass a $mime_filename extension-blocking protection mechanism, and potentially deliver executable attachments to the mailboxes of end users. | ||||
| CVE-2022-3620 | 2 Exim, Fedoraproject | 2 Exim, Fedora | 2025-05-23 | 5.6 Medium |
| A vulnerability was found in Exim and classified as problematic. This issue affects the function dmarc_dns_lookup of the file dmarc.c of the component DMARC Handler. The manipulation leads to use after free. The attack may be initiated remotely. The name of the patch is 12fb3842f81bcbd4a4519d5728f2d7e0e3ca1445. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-211919. | ||||
| CVE-2017-16944 | 2 Debian, Exim | 2 Debian Linux, Exim | 2025-04-20 | N/A |
| 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-2016-9963 | 3 Canonical, Debian, Exim | 3 Ubuntu Linux, Debian Linux, Exim | 2025-04-20 | N/A |
| 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-2017-16943 | 2 Debian, Exim | 2 Debian Linux, Exim | 2025-04-20 | N/A |
| 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 | 2025-04-20 | 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-2014-2972 | 1 Exim | 1 Exim | 2025-04-12 | 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-2016-1531 | 1 Exim | 1 Exim | 2025-04-12 | N/A |
| Exim before 4.86.2, when installed setuid root, allows local users to gain privileges via the perl_startup argument. | ||||
| CVE-2014-2957 | 1 Exim | 1 Exim | 2025-04-12 | 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-2010-2024 | 1 Exim | 1 Exim | 2025-04-11 | N/A |
| transports/appendfile.c in Exim before 4.72, when MBX locking is enabled, allows local users to change permissions of arbitrary files or create arbitrary files, and cause a denial of service or possibly gain privileges, via a symlink attack on a lockfile in /tmp/. | ||||
| CVE-2010-2023 | 1 Exim | 1 Exim | 2025-04-11 | N/A |
| transports/appendfile.c in Exim before 4.72, when a world-writable sticky-bit mail directory is used, does not verify the st_nlink field of mailbox files, which allows local users to cause a denial of service or possibly gain privileges by creating a hard link to another user's file. | ||||
| CVE-2011-1407 | 1 Exim | 1 Exim | 2025-04-11 | 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. | ||||
| CVE-2011-1764 | 1 Exim | 1 Exim | 2025-04-11 | 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. | ||||
