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-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-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-2012-5671 1 Exim 1 Exim 2025-04-11 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-2011-1407 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-2011-0017 1 Exim 1 Exim 2025-04-11 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-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.
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-2023-51766 3 Debian, Exim, Fedoraproject 4 Debian Linux, Exim, Extra Packages For Enterprise Linux and 1 more 2024-11-21 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-2022-37452 2 Debian, Exim 2 Debian Linux, Exim 2024-11-21 9.8 Critical
Exim before 4.95 has a heap-based buffer overflow for the alias list in host_name_lookup in host.c when sender_host_name is set.
CVE-2022-37451 2 Exim, Fedoraproject 2 Exim, Fedora 2024-11-21 7.5 High
Exim before 4.96 has an invalid free in pam_converse in auths/call_pam.c because store_free is not used after store_malloc.
CVE-2021-38371 1 Exim 1 Exim 2024-11-21 7.5 High
The STARTTLS feature in Exim through 4.94.2 allows response injection (buffering) during MTA SMTP sending.
CVE-2021-27216 1 Exim 1 Exim 2024-11-21 6.3 Medium
Exim 4 before 4.94.2 has Execution with Unnecessary Privileges. By leveraging a delete_pid_file race condition, a local user can delete arbitrary files as root. This involves the -oP and -oPX options.
CVE-2020-8015 2 Exim, Opensuse 2 Exim, Opensuse 2024-11-21 8.4 High
A UNIX Symbolic Link (Symlink) Following vulnerability in the packaging of exim in openSUSE Factory allows local attackers to escalate from user mail to root. This issue affects: openSUSE Factory exim versions prior to 4.93.0.4-3.1.
CVE-2020-28026 1 Exim 1 Exim 2024-11-21 9.8 Critical
Exim 4 before 4.94.2 has Improper Neutralization of Line Delimiters, relevant in non-default configurations that enable Delivery Status Notification (DSN). Certain uses of ORCPT= can place a newline into a spool header file, and indirectly allow unauthenticated remote attackers to execute arbitrary commands as root.
CVE-2020-28025 1 Exim 1 Exim 2024-11-21 7.5 High
Exim 4 before 4.94.2 allows Out-of-bounds Read because pdkim_finish_bodyhash does not validate the relationship between sig->bodyhash.len and b->bh.len; thus, a crafted DKIM-Signature header might lead to a leak of sensitive information from process memory.
CVE-2020-28024 1 Exim 1 Exim 2024-11-21 9.8 Critical
Exim 4 before 4.94.2 allows Buffer Underwrite that may result in unauthenticated remote attackers executing arbitrary commands, because smtp_ungetc was only intended to push back characters, but can actually push back non-character error codes such as EOF.
CVE-2020-28023 1 Exim 1 Exim 2024-11-21 7.5 High
Exim 4 before 4.94.2 allows Out-of-bounds Read. smtp_setup_msg may disclose sensitive information from process memory to an unauthenticated SMTP client.
