F-Prot F-Prot Antivirus 4.6.6

F-Prot Antivirus for Linux x86 Mail Servers 4.6.6 allows remote attackers to bypass virus detection by inserting invalid characters into base64 encoded content in a multipart/mixed MIME file, as demonstrated with the EICAR test file.

The scanning engine before 4.4.4 in F-Prot Antivirus before 6.0.9.0 allows remote attackers to cause a denial of service (engine crash) via a CHM file with a large nb_dir value that triggers an out-of-bounds read.

Multiple unspecified vulnerabilities in the scanning engine before 4.4.4 in F-Prot Antivirus before 6.0.9.0 allow remote attackers to cause a denial of service via (1) a crafted UPX-compressed file, which triggers an engine crash; (2) a crafted Microsoft Office file, which triggers an infinite loop; or (3) an ASPack-compressed file, which triggers an engine crash.
