The vulnerability is caused due to an integer overflow error in the "CYImage::LoadJPG()" method (YImage.dll) when allocating memory using the image dimension values. This can be exploited to cause a heap-based buffer overflow via a specially crafted JPG file. Successful exploitation may allow execution of arbitrary code, but requires a victim to allow photo sharing with an attacker. The vulnerability is confirmed in version 11.5.0.152. Other versions may also be affected. SOLUTION: Update to version 11.5.0.155. PROVIDED AND/OR DISCOVERED BY: Tielei Wang, Georgia Tech Information Security Center via Secunia.
