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.
CVE-2014-3956 4 Fedoraproject, Freebsd, Hp and 1 more 4 Fedora, Freebsd, Hpux and 1 more 2024-11-21 1.9 LOW 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-2009-4565 1 Sendmail 1 Sendmail 2024-11-21 7.5 HIGH N/A
sendmail before 8.14.4 does not properly handle a '\0' character in a Common Name (CN) field of an X.509 certificate, which (1) allows man-in-the-middle attackers to spoof arbitrary SSL-based SMTP servers via a crafted server certificate issued by a legitimate Certification Authority, and (2) allows remote attackers to bypass intended access restrictions via a crafted client certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408.
CVE-2009-1490 1 Sendmail 1 Sendmail 2024-11-21 5.0 MEDIUM N/A
Heap-based buffer overflow in Sendmail before 8.13.2 allows remote attackers to cause a denial of service (daemon crash) and possibly execute arbitrary code via a long X- header, as demonstrated by an X-Testing header.
CVE-2007-2246 2 Hp, Sendmail 2 Hp-ux, Sendmail 2024-11-21 7.8 HIGH N/A
Unspecified vulnerability in HP-UX B.11.00 and B.11.11, when running sendmail 8.9.3 or 8.11.1; and HP-UX B.11.23 when running sendmail 8.11.1; allows remote attackers to cause a denial of service via unknown attack vectors. NOTE: due to the lack of details from HP, it is not known whether this issue is a duplicate of another CVE such as CVE-2006-1173 or CVE-2006-4434.
CVE-2006-7176 2 Redhat, Sendmail 2 Enterprise Linux, Sendmail 2024-11-21 4.3 MEDIUM N/A
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-2006-7175 2 Redhat, Sendmail 2 Enterprise Linux, Sendmail 2024-11-21 7.5 HIGH N/A
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-2006-4434 1 Sendmail 1 Sendmail 2024-11-21 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-2006-1173 1 Sendmail 1 Sendmail 2024-11-21 5.0 MEDIUM N/A
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 1 Sendmail 1 Sendmail 2024-11-21 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 2024-11-20 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-2003-0694 11 Apple, Compaq, Freebsd and 8 more 18 Mac Os X, Mac Os X Server, Tru64 and 15 more 2024-11-20 10.0 HIGH 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-2003-0688 6 Compaq, Freebsd, Openbsd and 3 more 6 Tru64, Freebsd, Openbsd and 3 more 2024-11-20 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-2003-0681 8 Apple, Gentoo, Hp and 5 more 14 Mac Os X, Mac Os X Server, Linux and 11 more 2024-11-20 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-2003-0308 2 Debian, Sendmail 2 Debian Linux, Sendmail 2024-11-20 7.2 HIGH N/A
The Sendmail 8.12.3 package in Debian GNU/Linux 3.0 does not securely create temporary files, which could allow local users to gain additional privileges via (1) expn, (2) checksendmail, or (3) doublebounce.pl.
CVE-2003-0161 4 Compaq, Hp, Sendmail and 1 more 9 Tru64, Hp-ux, Hp-ux Series 700 and 6 more 2024-11-20 10.0 HIGH 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-2002-2423 1 Sendmail 1 Sendmail 2024-11-20 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-2002-2261 1 Sendmail 1 Sendmail 2024-11-20 7.5 HIGH 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-2002-1827 1 Sendmail 1 Sendmail 2024-11-20 2.1 LOW 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.
