It was discovered that there was an arbitrary code execution vulnerability in libcamunrar, a library to add unrar support to the Clam anti-virus software. This was caused by an integer overflow resulting in a negative value of the ``DestPos`` variable, which allows the attacker to write out of bounds when setting ``Mem[DestPos]``.
