Detail

A vulnerability has been found and corrected in xrdb:

xrdb.c in xrdb before 1.0.9 in X.Org X11R7.6 and earlier allows remote attackers to execute arbitrary commands via shell metacharacters in a hostname obtained from a (1) DHCP or (2) XDMCP message (CVE-2011-0465).

Packages for 2009.0 are provided as of the Extended Maintenance Program. Please visit this link to learn more: http://store.mandriva.com/product_info.php?cPath=149&products_id=490

The updated packages have been patched to correct this issue.

Title:	DSA-2213-1 x11-xserver-utils -- missing input sanitisation
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. The oldstable distribution, this problem has been fixed in version 7.3+6.
