CVE-2016-6264 uClibc: Integer overflow vulnerability leads to code execution on ARM architecture
It was found that 'BLT' instruction in libc/string/arm/memset.S checks for signed values. If parameter of memset is negative, then value added to the PC will be large. Attacker that controls the length parameter of memset can also control the value of PC register.
