The write_one_header function in mutt 1.5.23 does not properly handle newline characters at the beginning of a header, which allows remote attackers to cause a denial of service (crash) via a header with an empty body, which triggers a heap-based buffer overflow in the mutt_substrdup function. La función write_one_header en mutt 1.5.23 no maneja correctamente los caracteres de línea nueva al inicio de una cabecera, lo que permite a atacantes remotos causar una denegación de servicio (caída) a través de una cabecera con el cuerpo vacío, lo que provoca un desbordamiento de buffer basado en memoria dinámica en la función mutt_substrdup. • http://advisories.mageia.org/MGASA-2014-0509.html http://dev.mutt.org/trac/ticket/3716 http://lists.opensuse.org/opensuse-security-announce/2015-01/msg00002.html http://www.debian.org/security/2014/dsa-3083 http://www.mandriva.com/security/advisories?name=MDVSA-2014:245 http://www.mandriva.com/security/advisories?name=MDVSA-2015:078 http://www.openwall.com/lists/oss-security/2014/11/27/5 http://www.openwall.com/lists/oss-security/2014/11/27/9 http://www.securityfocus& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

Buffer overflow in copy.c in Mutt before 1.5.23 allows remote attackers to cause a denial of service (crash) via a crafted RFC2047 header line, related to address expansion. Desbordamiento de buffer en copy.c en Mutt anterior a 1.5.23 permite a atacantes remotos causar una denegación de servicio (caída) a través de una línea de cabecera RFC2047 manipulada, relacionado con la expansión de dirección. • http://lists.opensuse.org/opensuse-security-announce/2014-04/msg00001.html http://lists.opensuse.org/opensuse-updates/2014-03/msg00083.html http://lists.opensuse.org/opensuse-updates/2014-03/msg00085.html http://rhn.redhat.com/errata/RHSA-2014-0304.html http://www.debian.org/security/2014/dsa-2874 http://www.mutt.org/doc/devel/ChangeLog http://www.securityfocus.com/bid/66165 http://www.securitytracker.com/id/1029919 http://www.ubuntu.com/usn/USN-2147-1 https://access&# • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •

mutt_ssl.c in mutt 1.5.16 and other versions before 1.5.19, when OpenSSL is used, does not verify the domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate. En el archivo mutt_ssl.c en mutt versión 1.5.16 y otras versiones anteriores a 1.5.19, cuando es usado OpenSSL, no comprueba el nombre de dominio en el campo Common Name (CN) de un certificado X.509, que permite a los atacantes de tipo man-in-the-middle falsificar servidores SSL por medio de un certificado válido arbitrario. • http://dev.mutt.org/trac/ticket/3087 http://marc.info/?l=oss-security&m=125198917018936&w=2 http://www.openwall.com/lists/oss-security/2009/10/26/1 • CWE-310: Cryptographic Issues •
