3. Description:
X.Org is an open source implementation of the X Window System. It provides
basic low-level functionality that full-fledged graphical user interfaces
are designed upon.
Two integer overflow flaws were found in the X.Org 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 X.Org server. (CVE-2007-6429)
A memory corruption flaw was found in the X.Org 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 X.Org server. (CVE-2007-6427)
An input validation flaw was found in the X.Org server's XFree86-Misc
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 X.Org server. (CVE-2007-5760)
An information disclosure flaw was found in the X.Org 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 X server's address space. (CVE-2007-6428)
A flaw was found in the X.Org 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 xorg-x11-server should upgrade to these updated packages, which
contain backported patches to resolve these issues.
