Trillian IRC PRIVMSG Buffer Overflow Vulnerability
Trillian is an instant messaging client that supports a number of protocols (including IRC, ICQ, MSN). It is available for Microsoft Windows systems. A buffer overflow has been discovered in Trillian version .73 and .74. When processing a PRIVMSG command with an overly large sender name, a buffer overflow will occur resulting in memory corruption and a denial of service. Although not yet confirmed, because memory can be overwritten, it may be possible for arbitrary attacker-supplied code to be executed with the privileges of the client. |
