Description Huzaifa S. Sidhpurwala 2012-08-27 03:48:44 UTC
Security researcher miaubiz used the Address Sanitizer tool to discover two WebGL issues. The first issue is a use-after-free when WebGL shaders are called after being destroyed. The second issue exposes a problem with Mesa drivers on Linux, leading to a potentially exploitable crash.
