Affected versions	< 6.0.2
Unaffected versions	>= 6.0.2

F-PROT Antivirus is a multi-platform virus scanner for workstations and mail servers.

The following vulnerabilities were found:

Multiple errors when processing UPX, ASPack or Microsoft Office files (CVE-2008-3243).
Infinite Sergio Alvarez of n.runs AG reported an invalid memory access when processing a CHM file with a large nb_dir value (CVE-2008-3244).

A remote attacker could entice a user or automated system to scan a specially crafted file, leading to a crash or infinite loop.

There is no known workaround at this time.
