Description Andrej Nemec 2016-05-05 07:45:40 EDT

A vulnerability was found in gcc. Due to the inconsistent use of long and int for string/array length in cp-demangle.c there is an integer overflow that leads to a write access violation. The target crashes on an access violation at an address matching the destination operand of the instruction.
