DSA-2213-1 x11-xserver-utils -- missing input sanitization
- Date Reported:
- 08 Apr 2011
- Affected Packages:
- Security database references:
- In the Debian bugtracking system: Bug 621423.
In Mitre's CVE dictionary: CVE-2011-0465.
- More information:
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.
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.
For the testing distribution (wheezy), this problem will be fixed soon.
For the unstable distribution (sid), this problem has been fixed in version 7.6+2.
We recommend that you upgrade your x11-xserver-utils packages.
