The vulnerability is caused due to a boundary error when handling an ARJ block that is larger than 2600 bytes. This can be exploited to cause a stack-based buffer overflow when a specially crafted ARJ file is opened. Successful exploitation allows arbitrary code execution. The vulnerability has been confirmed in version 3.13, 4.23, and 4.26 BETA. Other versions may also be affected. SOLUTION: The vulnerability has been fixed in version 4.27 BETA.
