Scientific Linux Security Update : X11 client libraries on SL6.x i386/x86_64 (20141014)

medium Nessus Plugin ID 78841

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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.

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.

- 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.

Solution

Update the affected packages.
