This update for Mesa fixes the following issues :

Security issue fixed :

  - CVE-2019-5068: Fixed exploitable shared memory     permissions vulnerability (bsc#1156015).

This update was imported from the SUSE:SLE-15-SP1:Update update project.

Tim Brown discovered a shared memory permissions vulnerability in the Mesa 3D graphics library. Some Mesa X11 drivers use shared-memory XImages to implement back buffers for improved performance, but Mesa creates shared memory regions with permission mode 0777. An attacker can access the shared memory without any specific permissions.

For Debian 8 'Jessie', this problem has been fixed in version 10.3.2-1+deb8u2.

We recommend that you upgrade your mesa packages.
