Mesa provides a 3D graphics API that is compatible with Open Graphics
Library (OpenGL). It also provides hardware-accelerated drivers for
many popular graphics chips.
An out-of-bounds access flaw was found in Mesa. If an application
using Mesa exposed the Mesa API to untrusted inputs (Mozilla Firefox
does this), an attacker could cause the application to crash or,
