Overview

There is a buffer overflow vulnerability in the gaim_markup_extract_info_field() function, which could allow an unauthenticated, remote attacker to cause a denial of service or execute arbitrary code.

Description

Gaim is a multi-protocol instant messenger client available for a number of operating systems. There is a buffer overflow vulnerability in the gaim_markup_extract_info_field() function. This function is used by the Yahoo Messenger (YMSG) and MSN protocol handlers. Within this function, a buffer with a fixed size of 1024 bytes is allocated in memory.
