DESCRIPTION:
A security issue has been reported in X.Org xrdb, which can be
exploited by malicious, local users to gain escalated privileges or
by malicious people to compromise a vulnerable system.
The security issue is caused due to the xrdb utility not properly
escaping hostnames, which can be exploited to inject and execute
arbitrary shell commands with the privileges of the user running the
display manager (usually "root") via specially crafted hostnames.
Successful exploitation requires that the attacker can login via
XDMCP (discouraged in untrusted networks for security reasons) or set
a malicious hostname via e.g. DHCP (requires physical access to the
network or control over the DHCP server).
SOLUTION:
Update to xrdb version 1.0.9.
