An integer overflow in whoopsie before versions 0.2.52.5ubuntu0.1, 0.2.62ubuntu0.1, 0.2.64ubuntu0.1, 0.2.66, results in an out-of-bounds write to a heap allocated buffer when processing large crash dumps. This results in a crash or possible code-execution in the context of the whoopsie process.
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.
