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 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 2025-04-20 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-2014-2957 1 Exim 1 Exim 2025-04-12 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-2014-2972 1 Exim 1 Exim 2025-04-12 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-2016-1531 1 Exim 1 Exim 2025-04-12 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-2011-1764 1 Exim 1 Exim 2025-04-11 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 2025-04-11 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.
CVE-2012-5671 1 Exim 1 Exim 2025-04-11 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-2010-4344 4 Canonical, Debian, Exim and 1 more 4 Ubuntu Linux, Debian Linux, Exim and 1 more 2025-04-11 9.3 HIGH 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-2010-2024 1 Exim 1 Exim 2025-04-11 4.4 MEDIUM 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-2011-0017 1 Exim 1 Exim 2025-04-11 6.9 MEDIUM N/A
The open_log function in log.c in Exim 4.72 and earlier does not check the return value from (1) setuid or (2) setgid system calls, which allows local users to append log data to arbitrary files via a symlink attack.
CVE-2010-2023 1 Exim 1 Exim 2025-04-11 4.4 MEDIUM 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-2010-4345 4 Canonical, Debian, Exim and 1 more 4 Ubuntu Linux, Debian Linux, Exim and 1 more 2025-04-11 6.9 MEDIUM 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-2019-10149 3 Canonical, Debian, Exim 3 Ubuntu Linux, Debian Linux, Exim 2025-04-01 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 2025-03-14 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-2019-16928 4 Canonical, Debian, Exim and 1 more 4 Ubuntu Linux, Debian Linux, Exim and 1 more 2025-03-07 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-2023-51766 3 Debian, Exim, Fedoraproject 4 Debian Linux, Exim, Extra Packages For Enterprise Linux and 1 more 2024-11-21 N/A 5.3 MEDIUM
Exim before 4.97.1 allows SMTP smuggling in certain PIPELINING/CHUNKING configurations. Remote attackers can use a published exploitation technique to inject e-mail messages with a spoofed MAIL FROM address, allowing bypass of an SPF protection mechanism. This occurs because Exim supports <LF>.<CR><LF> but some other popular e-mail servers do not.
CVE-2022-3620 2 Exim, Fedoraproject 2 Exim, Fedora 2024-11-21 N/A 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.
