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. sendmail hasta al menos 8.14.7 permite el contrabando SMTP en ciertas configuraciones. • http://www.openwall.com/lists/oss-security/2023/12/24/1 http://www.openwall.com/lists/oss-security/2023/12/25/1 http://www.openwall.com/lists/oss-security/2023/12/26/5 http://www.openwall.com/lists/oss-security/2023/12/29/5 http://www.openwall.com/lists/oss-security/2023/12/30/1 http://www.openwall.com/lists/oss-security/2023/12/30/3 https://access.redhat.com/security/cve/CVE-2023-51765 https://bugzilla.redhat.com/show_bug.cgi?id=2255869 ht • CWE-345: Insufficient Verification of Data Authenticity •

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. ALPACA es un ataque de confusión de contenido de protocolo de capa de aplicación, que explota servidores TLS que implementan diferentes protocolos pero que usan certificados compatibles, como certificados multidominio o comodín. Un atacante de tipo MiTM que tenga acceso al tráfico de la víctima en la capa TCP/IP puede redirigir el tráfico de un subdominio a otro, resultando en a una sesión TLS válida. • https://alpaca-attack.com https://bugzilla.redhat.com/show_bug.cgi?id=1975623 https://lists.debian.org/debian-lts-announce/2022/11/msg00031.html • CWE-295: Improper Certificate Validation •

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. La función sm_close_on_exec en conf.c en sendmail anterior a 8.14.9 tiene argumentos en el orden erróneo, y como consecuencia evade configurar etiquetas FD_CLOEXEC esperadas, lo que permite a usuarios locales acceder a descriptores de archivos de número alto no intencionados a través de un programa de entrega de correo personalizado. • ftp://ftp.sendmail.org/pub/sendmail/RELEASE_NOTES http://advisories.mageia.org/MGASA-2014-0270.html http://lists.fedoraproject.org/pipermail/package-announce/2014-June/134349.html http://lists.opensuse.org/opensuse-updates/2014-06/msg00032.html http://lists.opensuse.org/opensuse-updates/2014-06/msg00033.html http://packetstormsecurity.com/files/126975/Slackware-Security-Advisory-sendmail-Updates.html http://secunia.com/advisories/57455 http://secunia.com/advisories/58628 http://security.gentoo.org&#x • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

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. sendmail anterior a v8.14.4 no maneja adecuadamente un carácter '\0' en un fichero Common Name (CN) de un certificado X.509; esto permite (1) a atacantes del tipo hombre-en-el-medio suplantar a su elección servidores SMTP basados en SSL utilizando un certificado de servidor manipulado expedido por una Autoridad Certificadora legítima y (2) a atacantes remotos evitar las restricciones de acceso pretendidas a través de un certificado cliente expedido por una Autoridad Certificadora legítima.
