The sdump function in sdump.c in fetchmail 6.3.11, 6.3.12, and 6.3.13, when running in verbose mode on platforms for which char is signed, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via an SSL X.509 certificate containing non-printable characters with the high bit set, which triggers a heap-based buffer overflow during escaping. La función sdump en sdum.c en fetchmail v6.3.11, v6.3.12 y v6.3.13, cuando está ejecutado en modo verbose sobre plataformas para las que los caracteres van firmados, permite a atacantes remotos provocar una denegación de servicio (caída de aplicación) o posiblemente la ejecución de código de su elección a través de un certificado X.509 que contiene caracteres no imprimibles con el bit más alto asignado, lo que provoca un desbordamiento de búfer basado en memoria dinámica (heap) durante el escape. • http://mknod.org/svn/fetchmail/branches/BRANCH_6-3/fetchmail-SA-2010-01.txt http://osvdb.org/62114 http://secunia.com/advisories/38391 http://www.fetchmail.info/fetchmail-SA-2010-01.txt http://www.mandriva.com/security/advisories?name=MDVSA-2010:037 http://www.securityfocus.com/bid/38088 http://www.securitytracker.com/id?1023543 http://www.vupen.com/english/advisories/2010/0296 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

socket.c in fetchmail before 6.3.11 does not properly handle a '\0' character in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408. socket.c en fetchmail antes de v6.3.11 no maneja correctamente un caracter '\ 0' en el nombre de dominio en el campo Common Name (CN) de un certificado X.509, lo cual permite a atacacantes hombre-en-el-medio (man-in-the-middle) suplantar servidores SSL a su elección a través de certificados manipulados expedidos por una Autoridad de Certificación (CA) legítima, una cuestión relacionada con CVE-2009-2408. • http://fetchmail.berlios.de/fetchmail-SA-2009-01.txt http://lists.apple.com/archives/security-announce/2009/Nov/msg00000.html http://marc.info/?l=oss-security&m=124949601207156&w=2 http://osvdb.org/56855 http://secunia.com/advisories/36175 http://secunia.com/advisories/36179 http://secunia.com/advisories/36236 http://support.apple.com/kb/HT3937 http://www.debian.org/security/2009/dsa-1852 http://www.mandriva.com/security/advisories?name=MDVSA-2009:201 http://www • CWE-310: Cryptographic Issues •

https://notcve.org/view.php?id=CVE-2008-2711
fetchmail 6.3.8 and earlier, when running in -v -v (aka verbose) mode, allows remote attackers to cause a denial of service (crash and persistent mail failure) via a malformed mail message with long headers, which triggers an erroneous dereference when using vsnprintf to format log messages. fetchmail versión 6.3.8 y anteriores, cuando se ejecuta en modo -v -v (también se conoce como verbose), permite a los atacantes remotos causar una denegación de servicio (bloqueo y fallo de correo persistente) por medio de un mensaje de correo malformado con encabezados largos, lo que desencadena unas desreferencias erróneas cuando se utiliza vsnprintf para dar formato a mensajes de registro. • http://lists.apple.com/archives/security-announce/2009/Feb/msg00000.html http://secunia.com/advisories/30742 http://secunia.com/advisories/30895 http://secunia.com/advisories/31262 http://secunia.com/advisories/31287 http://secunia.com/advisories/33937 http://slackware.com/security/viewer.php?l=slackware-security&y=2008&m=slackware-security.495740 http://support.apple.com/kb/HT3438 http://wiki.rpath.com/wiki/Advisories:rPSA-2008-0235 http://www.fetchmail.info/fetchmail-SA-2008-01&# • CWE-20: Improper Input Validation •
