Synopsis

The remote CentOS host is missing a security update for xorg-x11-server-Xwayland.

Description

The remote CentOS Linux 9 host has packages installed that are affected by a vulnerability as referenced in the xorg-x11-server-Xwayland-21.1.3-6.el9 build changelog.

 - A vulnerability was found in X.Org. This security flaw occurs becuase the swap handler for the XTestFakeInput request of the XTest extension may corrupt the stack if GenericEvents with lengths larger than 32 bytes are sent through a the XTestFakeInput request. This issue can lead to local privileges elevation on systems where the X server is running privileged and remote code execution for ssh X forwarding sessions. This issue does not affect systems where client and server use the same byte order.
 (CVE-2022-46340)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution
