Debian: DSA-2214-1 Critical: x11-server-utils Remote Code Exploitation

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.


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.

For the testing distribution (wheezy), this problem will be fixed soon.

For the testing distribution (sid), this problem has been fixed in
version 7.6+2.


We recommend that you upgrade your x11-xserver-utils packages.
