FreeBSD : xwayland -- Multiple vulnerabilities (7ac0f35a-7aeb-11f1-a315-589cfc10a551)

critical Nessus Plugin ID 325980

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 7ac0f35a-7aeb-11f1-a315-589cfc10a551 advisory.

 X.Org project reports:
 Multiple issues have been found in the X server and Xwayland implementations published by X.Org for which we are releasing security fixes for in xorg-server-21.1.24 and xwayland-24.1.13.

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

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

Solution

Update the affected packages.
