CVE-2002-2261 1 Sendmail 1 Sendmail 2026-04-16 N/A
Sendmail 8.9.0 through 8.12.6 allows remote attackers to bypass relaying restrictions enforced by the 'check_relay' function by spoofing a blank DNS hostname.
CVE-2001-0713 1 Sendmail 1 Sendmail 2026-04-16 N/A
Sendmail before 8.12.1 does not properly drop privileges when the -C option is used to load custom configuration files, which allows local users to gain privileges via malformed arguments in the configuration file whose names contain characters with the high bit set, such as (1) macro names that are one character long, (2) a variable setting which is processed by the setoption function, or (3) a Modifiers setting which is processed by the getmodifiers function.
CVE-2002-1165 3 Netbsd, Redhat, Sendmail 4 Netbsd, Enterprise Linux, Linux and 1 more 2026-04-16 N/A
Sendmail Consortium's Restricted Shell (SMRSH) in Sendmail 8.12.6, 8.11.6-15, and possibly other versions after 8.11 from 5/19/1998, allows attackers to bypass the intended restrictions of smrsh by inserting additional commands after (1) "||" sequences or (2) "/" characters, which are not properly filtered or verified.
CVE-2001-0714 1 Sendmail 1 Sendmail 2026-04-16 N/A
Sendmail before 8.12.1, without the RestrictQueueRun option enabled, allows local users to cause a denial of service (data loss) by (1) setting a high initial message hop count option (-h), which causes Sendmail to drop queue entries, (2) via the -qR option, or (3) via the -qS option.
CVE-2002-2423 1 Sendmail 1 Sendmail 2026-04-16 N/A
Sendmail 8.12.0 through 8.12.6 truncates log messages longer than 100 characters, which allows remote attackers to prevent the IP address from being logged via a long IDENT response.
CVE-2003-0681 9 Apple, Gentoo, Hp and 6 more 15 Mac Os X, Mac Os X Server, Linux and 12 more 2026-04-16 N/A
A "potential buffer overflow in ruleset parsing" for Sendmail 8.12.9, when using the nonstandard rulesets (1) recipient (2), final, or (3) mailer-specific envelope recipients, has unknown consequences.
CVE-2003-0688 6 Compaq, Freebsd, Openbsd and 3 more 7 Tru64, Freebsd, Openbsd and 4 more 2026-04-16 N/A
The DNS map code in Sendmail 8.12.8 and earlier, when using the "enhdnsbl" feature, does not properly initialize certain data structures, which allows remote attackers to cause a denial of service (process crash) via an invalid DNS response that causes Sendmail to free incorrect data.
CVE-2003-0694 12 Apple, Compaq, Freebsd and 9 more 20 Mac Os X, Mac Os X Server, Tru64 and 17 more 2026-04-16 N/A
The prescan function in Sendmail 8.12.9 allows remote attackers to execute arbitrary code via buffer overflow attacks, as demonstrated using the parseaddr function in parseaddr.c.
CVE-1999-1109 1 Sendmail 1 Sendmail 2026-04-16 N/A
Sendmail before 8.10.0 allows remote attackers to cause a denial of service by sending a series of ETRN commands then disconnecting from the server, while Sendmail continues to process the commands after the connection has been terminated.
CVE-2006-4434 1 Sendmail 1 Sendmail 2026-04-16 7.5 High
Use-after-free vulnerability in Sendmail before 8.13.8 allows remote attackers to cause a denial of service (crash) via a long "header line", which causes a previously freed variable to be referenced. NOTE: the original developer has disputed the severity of this issue, saying "The only denial of service that is possible here is to fill up the disk with core dumps if the OS actually generates different core dumps (which is unlikely)... the bug is in the shutdown code (finis()) which leads directly to exit(3), i.e., the process would terminate anyway, no mail delivery or receiption is affected."
CVE-2014-3956 4 Fedoraproject, Freebsd, Hp and 1 more 4 Fedora, Freebsd, Hpux and 1 more 2025-04-12 N/A
The sm_close_on_exec function in conf.c in sendmail before 8.14.9 has arguments in the wrong order, and consequently skips setting expected FD_CLOEXEC flags, which allows local users to access unintended high-numbered file descriptors via a custom mail-delivery program.
CVE-2023-51765 3 Freebsd, Redhat, Sendmail 3 Freebsd, Enterprise Linux, Sendmail 2024-11-21 5.3 Medium
sendmail through 8.17.2 allows SMTP smuggling in certain 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 sendmail supports <LF>.<CR><LF> but some other popular e-mail servers do not. This is resolved in 8.18 and later versions with 'o' in srv_features.
CVE-2021-3618 5 Debian, F5, Fedoraproject and 2 more 5 Debian Linux, Nginx, Fedora and 2 more 2024-11-21 7.4 High
ALPACA is an application layer protocol content confusion attack, exploiting TLS servers implementing different protocols but using compatible certificates, such as multi-domain or wildcard certificates. A MiTM attacker having access to victim's traffic at the TCP/IP layer can redirect traffic from one subdomain to another, resulting in a valid TLS session. This breaks the authentication of TLS and cross-protocol attacks may be possible where the behavior of one protocol service may compromise the other at the application layer.
