Gaim contains a buffer overflow vulnerability in the Extract Info Field function

Vulnerability Note VU#197142

Original Release Date: 2004-05-10 | Last Revised: 2004-05-10


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.
