Description:

Sergio Alvarez has reported some vulnerabilities in AVG Anti-Virus, which can be exploited by malicious people to cause a DoS (Denial of Service) or potentially compromise a vulnerable system.

 

1) An integer overflow error when parsing CAB archives can be exploited to cause a heap-based buffer overflow via a specially crafted CAB archive.

 

2) An unspecified error when parsing RAR archives can be exploited to cause a heap-based buffer overflow via a specially crafted RAR archive.

 

3) An uninitialized variable error exists within the parsing of CAB archives.

 

4) A division by zero error when parsing DOC files may in certain cases cause a DoS via a specially crafted DOC file.

 

5) An unspecified error exists within the parsing of EXE files.

 

The vulnerabilities are reported in AVG Antivirus software versions prior to 7.1.407.

 

Solution:

Update to the latest version.
