:Some vulnerabilities have been reported in Trillian, which can be exploited by malicious users to gain knowledge of sensitive information or compromise another 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.The vulnerabilities are reported in 3.1. Other versions may also be affected.Solution:Update to version 3.5.1.0.http://www.ceruleanstudios.com/downloads/Provided and/or discovered by:Discovered by enhalos and reported via iDefense Labs.Original Advisory:Cerulean Studios:http://blog.ceruleanstudios.com/?p=129#more-129iDefense Labs:http://labs.idefense.com/intelligence/vulnerabilities/display.php?id=522
