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.
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. When copying data, the function fails to check the size of the data copied to the buffer. This could result in a buffer overflow.
An unauthenticated, remote attacker could cause a denial of service or potentially execute arbitrary code with the privileges of the vulnerable process.
Upgrade to Gaim version 0.75 or later.
This vulnerability was publicly reported by Stefan Esser of e-matters.
