Synopsis
The remote Oracle Linux host is missing one or more security updates.Description
From Red Hat Security Advisory 2008:0029 :Updated XFree86 packages that fix several security issues are now available for Red Hat Enterprise Linux 2.1 and 3.
This update has been rated as having important security impact by the Red Hat Security Response Team.
[Updated 18th January 2008] The original packages distributed with this errata had a bug which could cause some X applications to fail on 32-bit platforms. We have updated the packages to correct this bug.
XFree86 is an implementation of the X Window System, which provides the core functionality for the Linux graphical desktop.
Two integer overflow flaws were found in the XFree86 server's EVI and MIT-SHM modules. A malicious authorized client could exploit these issues to cause a denial of service (crash), or potentially execute arbitrary code with root privileges on the XFree86 server.
(CVE-2007-6429)
A heap based buffer overflow flaw was found in the way the XFree86 server handled malformed font files. A malicious local user could exploit this issue to potentially execute arbitrary code with the privileges of the XFree86 server. (CVE-2008-0006)
A memory corruption flaw was found in the XFree86 server's XInput extension. A malicious authorized client could exploit this issue to cause a denial of service (crash), or potentially execute arbitrary code with root privileges on the XFree86 server. (CVE-2007-6427)
An information disclosure flaw was found in the XFree86 server's TOG-CUP extension. A malicious authorized client could exploit this issue to cause a denial of service (crash), or potentially view arbitrary memory content within the XFree86 server's address space.
(CVE-2007-6428)
An integer and heap overflow flaw were found in the X.org font server, xfs. A user with the ability to connect to the font server could have been able to cause a denial of service (crash), or potentially execute arbitrary code with the permissions of the font server.
(CVE-2007-4568, CVE-2007-4990)
A flaw was found in the XFree86 server's XC-SECURITY extension, that could have allowed a local user to verify the existence of an arbitrary file, even in directories that are not normally accessible to that user. (CVE-2007-5958)
Users of XFree86 are advised to upgrade to these updated packages, which contain backported patches to resolve these issues.
