Sendmail vulnerabilities

CVE-2023-51765 [MEDIUM] CWE-345 CVE-2023-51765: sendmail through 8.17.2 allows SMTP smuggling in certain configurations. Remote attackers can use a 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 . but some other popular e-mail servers do not. This is resolved in 8.18

CVE-2021-3618 [HIGH] CWE-295 CVE-2021-3618: ALPACA is an application layer protocol content confusion attack, exploiting TLS servers implementin 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 sess

CVE-2014-3956 [LOW] CWE-200 CVE-2014-3956: The sm_close_on_exec function in conf.c in sendmail before 8.14.9 has arguments in the wrong order, 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-2006-7175 [HIGH] CVE-2006-7175: The version of Sendmail 8.13.1-2 on Red Hat Enterprise Linux 4 Update 4 and earlier does not allow t The version of Sendmail 8.13.1-2 on Red Hat Enterprise Linux 4 Update 4 and earlier does not allow the administrator to disable SSLv2 encryption, which could cause less secure channels to be used than desired.

CVE-2006-7176 [MEDIUM] CVE-2006-7176: The version of Sendmail 8.13.1-2 on Red Hat Enterprise Linux 4 Update 4 and earlier does not reject The version of Sendmail 8.13.1-2 on Red Hat Enterprise Linux 4 Update 4 and earlier does not reject the "localhost.localdomain" domain name for e-mail messages that come from external hosts, which might allow remote attackers to spoof messages.

CVE-2006-4434 [HIGH] CWE-416 CVE-2006-4434: Use-after-free vulnerability in Sendmail before 8.13.8 allows remote attackers to cause a denial of 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

CVE-2006-1173 [MEDIUM] CWE-399 CVE-2006-1173: Sendmail before 8.13.7 allows remote attackers to cause a denial of service via deeply nested, malfo Sendmail before 8.13.7 allows remote attackers to cause a denial of service via deeply nested, malformed multipart MIME messages that exhaust the stack during the recursive mime8to7 function for performing 8-bit to 7-bit conversion, which prevents Sendmail from delivering queued messages and might lead to disk consumption by core dump files.

CVE-2006-0058 [HIGH] CVE-2006-0058: Signal handler race condition in Sendmail 8.13.x before 8.13.6 allows remote attackers to execute ar 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 [MEDIUM] CVE-2005-2070: The ClamAV Mail fILTER (clamav-milter) 0.84 through 0.85d, when used in Sendmail using long timeouts 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.
