DoS vulnerability in F-Prot eliminated
The security services provider n.runs says that in late April this year Frisk, the Icelandic vendor of F-Prot antivirus software, eliminated a vulnerability in its scan engine for Windows that could have allowed attackers to make the scanner crash. Frisk had previously been advised of the problem by n.runs, but apparently there were problems with further communications, leaving n.runs uncertain of the outcome. Normally, n.runs doesn't publish its reports until a vulnerability has been eliminated.
This it has now done. The cause of the vulnerability is a faulty memory access that occurs when crafted CHM files are parsed. All versions of the scan engine before 4.4.4 are affected.
