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.
