Gentoo: GLSA-201206-19: NVIDIA Drivers: Privilege escalation
Summary
A vulnerability has been found in the way NVIDIA drivers handle
read/write access to GPU device nodes, allowing access to arbitrary
system memory locations.
NOTE: Exposure to this vulnerability is reduced in Gentoo due to 660
permissions being used on the GPU device nodes by default.
Resolution
All NVIDIA driver users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot -v ">=x11-drivers/nvidia-drivers-295.40"
