Title: AVG Anti-Virus Multiple Remote Code Execution Vulnerabilities
Severity: CRITICAL
Description:
AVG Anti-Virus is an antivirus application available for the Microsoft Windows platform.
AVG Anti-Virus is prone to multiple remote code-execution vulnerabilities because of flaws in the software's file-parsing engine. Specifically, the following issues are present:
a heap-based buffer overflow due to an integer overflow while parsing CAB files
an uninitialized-variable issue while parsing CAB files
a divide-by-zero denial-of-service issue while parsing DOC files
a heap-based buffer overflow due to an integer overflow while parsing RAR files
unspecified integer-related issues while parsing EXE files.
Successfully exploiting these issues allows remote attackers to execute code with elevated privileges, facilitating the complete compromise of affected computers.
AVG Anti-Virus versions prior to 7.1.407 are vulnerable to these issues.
Affected Products:
- AVG AVG Anti-Virus 6.0.710
- AVG AVG Anti-Virus 7.0.0
- AVG AVG Anti-Virus 7.0.251
- AVG AVG Anti-Virus 7.0.323
- AVG AVG Anti-Virus 7.1.308
