RHEL 6 : X11 client libraries (RHSA-2014:1436)

critical Nessus Plugin ID 78411

Language:

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2014:1436 advisory.

The X11 (Xorg) libraries provide library routines that are used within all X Window applications.

Multiple integer overflow flaws, leading to heap-based buffer overflows, were found in the way various X11 client libraries handled certain protocol data. An attacker able to submit invalid protocol data to an X11 server via a malicious X11 client could use either of these flaws to potentially escalate their privileges on the system. (CVE-2013-1981, CVE-2013-1982, CVE-2013-1983, CVE-2013-1984, CVE-2013-1985, CVE-2013-1986, CVE-2013-1987, CVE-2013-1988, CVE-2013-1989, CVE-2013-1990, CVE-2013-1991, CVE-2013-2003, CVE-2013-2062, CVE-2013-2064)

Multiple array index errors, leading to heap-based buffer out-of-bounds write flaws, were found in the way various X11 client libraries handled data returned from an X11 server. A malicious X11 server could possibly use this flaw to execute arbitrary code with the privileges of the user running an X11 client. (CVE-2013-1997, CVE-2013-1998, CVE-2013-1999, CVE-2013-2000, CVE-2013-2001, CVE-2013-2002, CVE-2013-2066)

A buffer overflow flaw was found in the way the XListInputDevices() function of X.Org X11's libXi runtime library handled signed numbers.
A malicious X11 server could possibly use this flaw to execute arbitrary code with the privileges of the user running an X11 client. (CVE-2013-1995)

A flaw was found in the way the X.Org X11 libXt runtime library used uninitialized pointers. A malicious X11 server could possibly use this flaw to execute arbitrary code with the privileges of the user running an X11 client. (CVE-2013-2005)

Two stack-based buffer overflow flaws were found in the way libX11, the Core X11 protocol client library, processed certain user-specified files.
A malicious X11 server could possibly use this flaw to crash an X11 client via a specially crafted file. (CVE-2013-2004)

The xkeyboard-config package has been upgraded to upstream version 2.11, which provides a number of bug fixes and enhancements over the previous version. (BZ#1077471)

This update also fixes the following bugs:

* Previously, updating the mesa-libGL package did not update the libX11 package, although it was listed as a dependency of mesa-libGL. This bug has been fixed and updating mesa-libGL now updates all dependent packages as expected. (BZ#1054614)

* Previously, closing a customer application could occasionally cause the X Server to terminate unexpectedly. After this update, the X Server no longer hangs when a user closes a customer application. (BZ#971626)

All X11 client libraries users are advised to upgrade to these updated packages, which correct these issues and add these enhancements.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
