Title: AOL Instant Messenger Large BuddyIcon Denial of Service Vulnerability
Severity: MODERATE
Description:
AOL Instant Messenger (AIM) is a real time messaging service for on line users. AIM uses a feature called BuddyIcons, which determines a users on line status using images.
A vulnerability exists in AOL Instant Messenger (AIM) which could cause the AIM client to stop responding.
AIM does not properly check the size of a user's BuddyIcon when sending instant messages. Therefore, a user with an unusually large BuddyIcon image display dimensions sending instant messages, could cause the target clients to stop responding.
A restart of the application may be necessary in order to regain normal functionality.
This issue may be the result of an unchecked buffer. If this is the case, there is a possibility that arbitrary code may be executed on the vulnerable target. However, this has not yet been confirmed.
Affected Products:
- AOL Instant Messenger 4.7.0
