Descriptions

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 (formerly Gaim) before 2.5.6 on 32-bit platforms allow remote attackers to execute arbitrary code via a malformed SLP message with a crafted offset value, leading to buffer overflows. NOTE: this issue exists because of an incomplete fix for CVE-2008-2927.

Múltiples desbordamientos de entero en las funciones msn_slplink_process_msg en el manejador del protocolo de MSN en (1) libpurple/protocols/msn/slplink.c y (2) libpurple/protocols/msnp9/slplink.c en Pidgin anterior a v2.5.6 en plataformas de 32 bits permite a atacantes remotos ejecutar código arbitrario a través de un mensaje mal formado con un valor de offset manipulado, que produce un desbordamiento de búfer. NOTA: Este hecho se produce por un arreglo incompleto de CVE-2008-2927.

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. By providing a specific value, an attacker can overflow a heap buffer resulting in arbitrary code execution.
