A VMSF_DELTA memory corruption exists in unrar prior to 5.5.5, as used in Sophos Anti-Virus Threat Detection Engine prior to 3.37.2 and other products, that can lead to arbitrary code execution. An integer overflow can be caused in DataSize+CurChannel. The result is a negative value of the "DestPos" variable, which allows the malicious user to write out of bounds when setting Mem[DestPos].
