Who is Vulnerable?
Vulnerability Description	HAURI anti-virus is a product line consisting of several antivirus scanners for both desktop and server systems. The product line is capable of scanning inside archived files. It supports numerous archive formats, one of which is the widely used ACE compression format. A buffer overflow vulnerability exists in HAURI Anti-Virus products. The flaw exists in the scanning of ACE archives containing compressed files with overly long names. A malicious user may exploit this vulnerability to bypass virus scanning, or execute arbitrary code on the affected system. In a simple attack case aimed at evading virus detection, the vulnerable program reports no detected viruses in the crafted ACE archive. In a more sophisticated attack scenario, where the malicious user is successful in injecting and executing supplied code, the behavior of the system is dependent on the nature of the injected code. Any code injected into the vulnerable component will execute in the security context of the current logged on user.
