Description

The version of F-PROT Anti-Virus installed on the remote Windows host contains flaws in the way it handles CHM, UPX-compressed, ASPack-compressed and certain Microsoft office files.

  • A malformed CHM file containing '0xffffffff' in the 'nb_dir' field could crash the application.

  • A malformed UPX-compressed or ASPack-compressed file could crash the application.

  • A specially crafted Microsoft office document could trigger a infinite loop, causing a denial of service condition.
