Security company Secunia, posted an advisory
saying that AVG Anti-Virus version 7.1.407 contains a flaw that can allow "malicious people to cause a DoS (Denial of Service) or potentially
compromise a vulnerable system."
"An integer overflow error when parsing CAB archives can be exploited to cause a heap-based buffer overflow via a specially crafted CAB archive.
An unspecified error when parsing RAR archives can be exploited to cause a heap-based buffer overflow via a specially crafted RAR archive.
An uninitialized variable error exists within the parsing of CAB archives," Secunia said in the advisory.
The solution of this flaw was already posted and it is represented by the installation of the latest version of the anti-virus solution.
AVG Anti-Virus is one of the most popular antivirus software because it is free to use, while for other solutions, you must pay a huge price.
