- def mallocMemcpyIntOverflow(): Query
Find calls to malloc where the first argument contains an arithmetic expression, the allocated buffer flows into memcpy as the first argument, and the third argument of that memcpy is unequal to the first argument of malloc.
Find calls to malloc where the first argument contains an arithmetic expression, the allocated buffer flows into memcpy as the first argument, and the third argument of that memcpy is unequal to the first argument of malloc. This is an adaption of the old-joern query first shown at 31C3 that found a buffer overflow in VLC's MP4 demuxer (CVE-2014-9626).
