There is an integer overflow vulnerability in the handlehdr_odc() function, which could allow an unauthenticated, remote attacker to cause a denial of service or potentially execute arbitrary code.
Gaim is a multi-protocol instant messenger client available for a number of operating systems. It supports a variety of instant messaging protocols, including the AIM/OSCAR protocol suite. There is an integer overflow vulnerability in the handlehdr_odc() function. This function fails to properly allocate memory when processing AIM/OSCAR DirectIM packets. By supplying a specially crafted value for the payloadlength variable, an unauthenticated, remote attacker could trigger a heap 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.
