Overview
America Online's Instant Messenger (AIM) contains a remotely exploitable buffer overflow vulnerability.
Description
AOL Instant Messenger is a widely used program for communicating with other users over the Internet. A buffer overflow exists in the processing of the addbuddy parameter of the AIM URI handler. A URI can be sent by another AIM user, embedded in a web site, or sent in an HTML-renderable email message. |
Impact
A denial-of-service situation is caused. It has not been determined if this vulnerability can lead to the remote execution of code. |
Solution
Block AIM Authentication at the Firewall Blocking connections to login.oscar.aol.com on port 5190/tcp may prevent users on the local network from authenticating to the AIM server. This may be sufficient to prevent the vulnerability from being exploited. |
