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.
