Multiple IRC Vulnerabilities in Trillian

Multiple vulnerabilities have been discovered in Trillian versions 3.1 and lower IRC module.
When handling long CTCP PING messages containing UTF-8 characters, it is possible to cause the Trillian IRC client to return a malformed response to the server. This malformed response is truncated and is missing the terminating newline character. This could allow the next line sent to the server to be improperly sent to an attacker.
When a user highlights a URL in an IRC message window Trillian copies the data to an internal buffer. If the URL contains a long string of UTF-8 characters, it is possible to overflow a heap based buffer corrupting memory in a way that could allow for code execution.
A heap overflow can be triggered remotely when the Trillian IRC module receives a message that contains a font face HTML tag with the face attribute set to a long UTF-8 string.”
All Trillian users that use it to connect to any IRC server or IRC network are urged to immediately upgrade to Trillian 3.1.5.0 or better or use a (safe and full featured) IRC client.
