CVE-2008-2927 – Multiple Vendor libpurple MSN Protocol SLP Message Heap Overflow Vulnerability

https://notcve.org/view.php?id=CVE-2008-2927

Multiple integer overflows in the msn_slplink_process_msg functions in the MSN protocol handler in (1) libpurple/protocols/msn/slplink.c and (2) libpurple/protocols/msnp9/slplink.c in Pidgin before 2.4.3 and Adium before 1.3 allow remote attackers to execute arbitrary code via a malformed SLP message with a crafted offset value, a different vulnerability than CVE-2008-2955. Múltiples desbordamiento de enteros en las funciones msn_slplink_process_msg en el manejador de protocolo MSN en los archivos (1) libpurple/protocols/msn/slplink.c y (2) libpurple/protocols/msnp9/slplink.c en Pidgin anterior a versión 2.4.3 y Adium anterior a versión 1.3, permiten a los atacantes remotos ejecutar código arbitrario por medio de un mensaje SLP malformado con un valor de desplazamiento diseñado, una vulnerabilidad diferente de CVE-2008-2955. This vulnerability allows remote attackers to execute arbitrary code on systems with vulnerable installations of messaging applications that make use of the libpurple library. User interaction is not required to exploit this vulnerability. The specific flaw exists in the implementation of the MSN protocol, specifically the handling of SLP messages. The function msn_slplink_process_msg() fails to properly validate an offset value specified in the SLP packet. • http://developer.pidgin.im/viewmtn/revision/diff/6eb1949a96fa80a4c744fc749c2562abc4cc9ed6/with/c3831c9181f4f61b747321240086ee79e4a08fd8/libpurple/protocols/msn/slplink.c http://developer.pidgin.im/viewmtn/revision/diff/6eb1949a96fa80a4c744fc749c2562abc4cc9ed6/with/c3831c9181f4f61b747321240086ee79e4a08fd8/libpurple/protocols/msnp9/slplink.c http://secunia.com/advisories/30971 http://secunia.com/advisories/31016 http://secunia.com/advisories/31105 http://secunia.com/advisories/31387 http://secunia.com/advisories/31642 http://secunia.com/advisories/ • CWE-189: Numeric Errors CWE-190: Integer Overflow or Wraparound •
