Description:
Some vulnerabilities have been reported in Trillian, which can be exploited by malicious people to gain knowledge of sensitive information or compromise a user's system.
1) An error within the copy operation in an IRC message window (by highlighting the text) can be exploited to cause a heap-based buffer overflow via an overly long URL string consisting of UTF-8 characters.
Successful exploitation may allow execution of arbitrary code, but requires that a user is tricked into e.g. highlighting the malicious URL in an IRC message window.
2) An error within the IRC module can be exploited to cause a heap-based buffer overflow via an overly long, specially crafted message containing a font face HTML tag with the face attribute set to a long UTF-8 string.
Successful exploitation may allow execution of arbitrary code.
3) An error within the handling of CTCP PING messages containing UTF-8 characters can be exploited to make the client return a malformed response with no terminating newline character. This could allow the next line to be sent to the attacker instead of the server.
4) An error within the Rendezvous / XMPP (Extensible Messaging and Presence Protocol) messaging subsystem can be exploited to cause a heap-based buffer overflow via a specially crafted message sent to default port 5298/TCP.
Successful exploitation allows execution of arbitrary code.
The vulnerabilities are reported in version 3.1. Other versions may also be affected.
Solution:
Update to version 3.1.5.1.
