Package : x11-xserver-utils
Vulnerability : missing input sanitization
Problem type : remote
Debian-specific: no
CVE ID : CVE-2011-0465
Debian bug : 621423
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.
