Description Alexander Bergmann 2024-01-16 12:29:22 UTC

CVE-2024-0408: SELinux unlabeled GLX PBuffer

Introduced in: xorg-server-1.10.0 (2011)
Fixed in: xorg-server-21.1.11 and xwayland-23.2.4
Fix: https://gitlab.freedesktop.org/xorg/xserver/-/commit/e5e8586a12a3ec915673edffa10dc8fe5e15dac3
Found by: Olivier Fourdan and Donn Seeley

The XSELINUX code in the Xserver labels the X resources based on a hook. What
happens here is that the GLX PBuffer code does not call that XACE hook when
creating the buffer, so it remains unlabeled, and when the client issues
another request to access that resource (as here with a GetGeometry) or even
when it creates another resource which needs to access that buffer (such as a
GC), the XSELINUX code will try to use an object that was never labeled and
crash because the SID is NULL.

xorg-server-21.1.11 and xwayland-23.2.4 have been patched to fix this issue.
