Description:
Secunia Research has discovered a vulnerability in various HAURI anti-virus products, which can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to a boundary error in the ACE archive decompression library (vrAZace.dll) when extracting an archive. This can be exploited to cause a stack-based buffer overflow when scanning a malicious ACE archive containing a compressed file with a filename longer than 272 characters.
Successful exploitation allows execution of arbitrary code, but requires that compressed file scanning is enabled.
