Description:
Evgeny Legerov has reported two vulnerabilities in F-PROT Antivirus, which can be exploited by malicious people to cause a DoS (Denial of Service) or potentially compromise a vulnerable system.
1) An error within the processing of ACE files can be exploited to cause an infinite loop that consumes available CPU resources.
2) An error within the processing of CHM files can be exploited to cause a heap-based buffer overflow via a specially crafted CHM file.
The vulnerabilities are reported in version 4.6.6. Prior versions may also be affected.
Solution:
Update to version 4.6.7.
