Bug 857780 – <x11-base/xorg-server-21.1.4 <x11-base/xwayland-22.1.3: multiple vulnerabilities

• Status: RESOLVED FIXED
• Product: Gentoo Security

[Description Matthew Smith 2022-07-12 17:00:44 UTC]

Multiple input validation failures in X server extensions
=========================================================

All theses issues can lead to local privileges elevation on systems
where the X server is running privileged and remote code execution for
ssh X forwarding sessions.

* CVE-2022-2319/ZDI-CAN-16062: X.Org Server ProcXkbSetGeometry Out-Of-Bounds
Access

The handler for the ProcXkbSetGeometry request of the Xkb extension does
not properly validate the request length leading to out of bounds memory
write.

* CVE-2022-2320/ZDI-CAN-16070: X.Org Server ProcXkbSetDeviceInfo Out-Of-Bounds
Access

The handler for the ProcXkbSetDeviceInfo request of the Xkb extension
does not properly validate the request length leading to out of bounds
memory write.

Dropping version from summary as there's no fixed version in tree yet.
