CVE-2016-1649: Buffer Overflow
First published: Tue Mar 29 2016(Updated: )
The Program::getUniformInternal function in Program.cpp in libANGLE, as used in Google Chrome before 49.0.2623.108, does not properly handle a certain data-type mismatch, which allows remote attackers to cause a denial of service (buffer overflow) or possibly have unspecified other impact via crafted shader stages.
