The remote host is vulnerable to format string flaw
The remote host is running AOL Instant Messenger (AIM). Version 4.1.2010 of AIM is vulnerable to a format string attack that may exploited by an attacker to crash a victim's IM client, leading to a denial of service. The vulnerability lies in AIM's improper handling of file transfers of filenames containing "%s".
Upgrade to the latest version of AOL Instant Messenger.
