This update of xorg-x11-libs fixes several integer and buffer overflow issues. (bnc#815451, bnc#821663)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Multiple integer overflows in X.org libdmx 1.1.2 and earlier allow X servers to trigger allocation of     insufficient memory and a buffer overflow via vectors related to the (1) DMXGetScreenAttributes, (2)     DMXGetWindowAttributes, and (3) DMXGetInputAttributes functions. (CVE-2013-1992)

Note that Nessus relies on the presence of the package as reported by the vendor.

Update to latest git to fix the following CVEs: CVE-2013-1992

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote host is affected by the vulnerability described in GLSA-201405-07 (X.Org X Server: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in X.Org X Server. Please       review the CVE identifiers referenced below for details.
  Impact :

    A context-dependent attacker could execute arbitrary code with the       privileges of the process, cause a Denial of Service condition, or obtain       sensitive information.
  Workaround :

    There is no known workaround at this time.

This update of xorg-x11-libs fixes several integer and buffer overflow issues.

Bug 815451/821663

CVE-2013-1984 / CVE-2013-1985 / CVE-2013-1986 / CVE-2013-1988 / CVE-2013-1990 / CVE-2013-1991 / CVE-2013-1992 / CVE-2013-1995 / CVE-2013-1996 / CVE-2013-1998 / CVE-2013-1999 / CVE-2013-2000 / CVE-2013-2001 / CVE-2013-2003 / CVE-2013-2063

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.
