SynopsisThe remote CentOS host is missing one or more security updates.
DescriptionUpdated X.org packages that fix several security issues are now available for Red Hat Enterprise Linux 4.
This update has been rated as having important security impact by the Red Hat Security Response Team.
X.org is an open source implementation of the X Window System. It provides the basic low-level functionality that full-fledged graphical user interfaces are designed upon.
iDefense reported an integer overflow flaw in the X.org XC-MISC extension. A malicious authorized client could exploit this issue to cause a denial of service (crash) or potentially execute arbitrary code with the privileges of the X.org server. (CVE-2007-1003)
iDefense reported two integer overflows in the way X.org handled various font files. A malicious local user could exploit these issues to potentially execute arbitrary code with the privileges of the X.org server. (CVE-2007-1351, CVE-2007-1352)
An integer overflow flaw was found in the X.org XGetPixel() function.
Improper use of this function could cause an application calling it to function improperly, possibly leading to a crash or arbitrary code execution. (CVE-2007-1667)
Users of X.org should upgrade to these updated packages, which contain a backported patch and are not vulnerable to these issues.
SolutionUpdate the affected xorg packages.
