For further product information on the TippingPoint IPS, visit: http://www.tippingpoint.com - -- Vulnerability Details: This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Trillian. User interaction is required to exploit this vulnerability in that the target must open a malicious image file. The specific flaws exists during the parsing of messages with overly long attribute values within the FONT tag. The value for any attribute is copied into a stack based buffer via sprintf() which can result in a buffer overrun and can be subsequently leveraged to execute arbitrary code under the privileges of the logged in user. Exploitation may occur over the AIM network or via direct connections. - -- Vendor Response: Trillian v3.1.10.0 has been released to address these vulnerabilities and is available at http://www.ceruleanstudios.com/downloads/ - -- Disclosure Timeline: 2007-12-03 - Vulnerability reported to vendor 2008-05-21 - Coordinated public release of advisory - -- Credit: This vulnerability was discovered by: * Anonymous - -- About the Zero Day Initiative (ZDI): Established by TippingPoint, The Zero Day Initiative (ZDI) represents a best-of-breed model for rewarding security researchers for responsibly disclosing discovered vulnerabilities. Researchers interested in getting paid for their security research through the ZDI can find more information and sign-up at: http://www.zerodayinitiative.com The ZDI is unique in how the acquired vulnerability information is used. TippingPoint does not re-sell the vulnerability details or any exploit code. Instead, upon notifying the affected product vendor, TippingPoint provides its customers with zero day protection through its intrusion prevention technology.
