Description Andrej Nemec 2017-03-17 08:05:10 UTC

Integer overflow in the cs_winkernel_malloc function in winkernel_mm.c
in Capstone 3.0.4 and earlier allows attackers to cause a denial of
service (heap-based buffer overflow in a kernel driver) or possibly
have unspecified other impact via a large value.
