CVE-1999-1109 1 Sendmail 1 Sendmail 2025-04-03 5.0 MEDIUM 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-2003-0688 6 Compaq, Freebsd, Openbsd and 3 more 6 Tru64, Freebsd, Openbsd and 3 more 2025-04-03 5.0 MEDIUM 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-2001-0715 1 Sendmail 1 Sendmail 2025-04-03 2.1 LOW N/A
Sendmail before 8.12.1, without the RestrictQueueRun option enabled, allows local users to obtain potentially sensitive information about the mail queue by setting debugging flags to enable debug mode.
CVE-2006-4434 1 Sendmail 1 Sendmail 2025-04-03 5.0 MEDIUM 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-1999-0478 1 Sendmail 1 Sendmail 2025-04-03 5.0 MEDIUM N/A
Denial of service in HP-UX sendmail 8.8.6 related to accepting connections.
CVE-2006-0058 1 Sendmail 1 Sendmail 2025-04-03 7.6 HIGH N/A
Signal handler race condition in Sendmail 8.13.x before 8.13.6 allows remote attackers to execute arbitrary code by triggering timeouts in a way that causes the setjmp and longjmp function calls to be interrupted and modify unexpected memory locations.
CVE-2005-2070 1 Sendmail 1 Sendmail 2025-04-03 5.0 MEDIUM N/A
The ClamAV Mail fILTER (clamav-milter) 0.84 through 0.85d, when used in Sendmail using long timeouts, allows remote attackers to cause a denial of service by keeping an open connection, which prevents ClamAV from reloading.
CVE-2001-1349 1 Sendmail 1 Sendmail 2025-04-03 3.7 LOW N/A
Sendmail before 8.11.4, and 8.12.0 before 8.12.0.Beta10, allows local users to cause a denial of service and possibly corrupt the heap and gain privileges via race conditions in signal handlers.
CVE-1999-1309 1 Sendmail 1 Sendmail 2025-04-03 7.2 HIGH N/A
Sendmail before 8.6.7 allows local users to gain root access via a large value in the debug (-d) command line option.
CVE-2003-0681 8 Apple, Gentoo, Hp and 5 more 14 Mac Os X, Mac Os X Server, Linux and 11 more 2025-04-03 7.5 HIGH 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-2002-2423 1 Sendmail 1 Sendmail 2025-04-03 6.4 MEDIUM 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-2023-51765 3 Freebsd, Redhat, Sendmail 3 Freebsd, Enterprise Linux, Sendmail 2024-11-21 N/A 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 5.8 MEDIUM 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.
