Trillian IRC URL highlight buffer overflow
| trillian-urlhighlight-bo (33985) |  High Risk |
Description:
Trillian is vulnerable to a heap-based buffer overflow, caused by improper bounds checking when highlighting URLs in the IRC module. By sending an overly long specially-crafted UTF-8 encoded URL, a remote attacker could overflow a buffer and possibly execute arbitrary code on the system, once the victim highlights the URL.
Platforms Affected:
- Cerulean Studios, Trillian prior to 3.1.5.0
Remedy:
Upgrade to the latest version of Trillian (3.1.5.0 or later), available from the Trillian Web site. See References.
Consequences:
Gain Access
