CVE-2001-0653 2 Redhat, Sendmail 2 Linux, Sendmail 2026-04-16 N/A
Sendmail 8.10.0 through 8.11.5, and 8.12.0 beta, allows local users to modify process memory and possibly gain privileges via a large value in the 'category' part of debugger (-d) command line arguments, which is interpreted as a negative number.
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-2002-0906 1 Sendmail 1 Sendmail 2026-04-16 N/A
Buffer overflow in Sendmail before 8.12.5, when configured to use a custom DNS map to query TXT records, allows remote attackers to cause a denial of service and possibly execute arbitrary code via a malicious DNS server.
CVE-2003-0161 5 Compaq, Hp, Redhat and 2 more 11 Tru64, Hp-ux, Hp-ux Series 700 and 8 more 2026-04-16 N/A
The prescan() function in the address parser (parseaddr.c) in Sendmail before 8.12.9 does not properly handle certain conversions from char and int types, which can cause a length check to be disabled when Sendmail misinterprets an input value as a special "NOCHAR" control value, allowing attackers to cause a denial of service and possibly execute arbitrary code via a buffer overflow attack using messages, a different vulnerability than CVE-2002-1337.
CVE-2002-1827 1 Sendmail 1 Sendmail 2026-04-16 N/A
Sendmail 8.9.0 through 8.12.3 allows local users to cause a denial of service by obtaining an exclusive lock on the (1) alias, (2) map, (3) statistics, and (4) pid files.
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-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-2002-1337 8 Gentoo, Hp, Netbsd and 5 more 11 Linux, Alphaserver Sc, Hp-ux and 8 more 2026-04-16 N/A
Buffer overflow in Sendmail 5.79 to 8.12.7 allows remote attackers to execute arbitrary code via certain formatted address fields, related to sender and recipient header comments as processed by the crackaddr function of headers.c.
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.
