FRISK Software F-Prot Antivirus before 4.6.7 allows user-assisted remote attackers to cause a denial of service (infinite loop) via a crafted ACE file. NOTE: this issue has at least a partial overlap with CVE-2006-6294.

Multiple unspecified vulnerabilities in FRISK Software F-Prot Antivirus before 4.6.7 have unspecified impact and attack vectors. NOTE: this might be related to CVE-2006-6293, but it is not clear due to the vagueness of the report.

Frisk F-Prot Antivirus allows remote attackers to bypass protection via a ZIP file with a version header greater than 15, which prevents F-Prot from decompressing and analyzing the file.

Multiple interpretation error in F-Prot 3.16c allows remote attackers to bypass virus scanning via a file such as BAT, HTML, and EML with an "MZ" magic byte sequence which is normally associated with EXE, which causes the file to be treated as a safe type that could still be executed as a dangerous file type by applications on the end system, as demonstrated by a "triple headed" program that contains EXE, EML, and HTML content, aka the "magic byte bug."

Multiple interpretation error in unspecified versions of F-Prot Antivirus allows remote attackers to bypass virus detection via a malicious executable in a specially crafted RAR file with malformed central and local headers, which can still be opened by products such as Winrar and PowerZip, even though they are rejected as corrupted by Winzip and BitZipper.
