Debian DSA-2213-1 : x11-xserver-utils - missing input sanitization

high Nessus Plugin ID 53340

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Sebastian Krahmer discovered that the xrdb utility of x11-xserver-utils, a X server resource database utility, is not properly filtering crafted hostnames. This allows a remote attacker to execute arbitrary code with root privileges given that either remote logins via xdmcp are allowed or the attacker is able to place a rogue DHCP server into the victims network.

Solution

Upgrade the x11-xserver-utils packages.

For the oldstable distribution (lenny), this problem has been fixed in version 7.3+6.

For the stable distribution (squeeze), this problem has been fixed in version 7.5+3.
