Buffer overflow in the goaway function in the aim:goaway URI handler for AOL Instant Messenger (AIM) 5.5, including 5.5.3595, allows remote attackers to execute arbitrary code via a long Away message.

The GIF parser in ateimg32.dll in AOL Instant Messenger (AIM) 5.9.3797 and earlier allows remote attackers to cause a denial of service (crash) via a malformed buddy icon that causes an integer underflow in a loop counter variable.

The Buddy icon file for AOL Instant Messenger (AIM) 4.3 through 5.5 is created in a predictable location, which may allow remote attackers to use a shell: URI to exploit other vulnerabilities that involve predictable locations.
