Multiple integer overflows in Grisoft AVG Anti-Virus before 7.1.407 allow remote attackers to execute arbitrary code via crafted (1) CAB or (2) RAR archives that trigger a heap-based buffer overflow. NOTE: some of these details are obtained from third party information.
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
