This Mesa update fixes the following security bug: CVE-2013-1993:
Integer overflows in XF86DRIOpenConnection and XF86DRIGetClientDriverName were fixed that could lead to client crashes when using a malicious X server.

This update fixes the following issue for Mesa on openSUSE 12.3 :

  - bnc#814947, fdo#62141: Make sure we do render between     two hiz flushes

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.

An out-of-bounds access flaw was found in Mesa. If an application using Mesa exposed the Mesa API to untrusted inputs (Mozilla Firefox does this), an attacker could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2013-1872)

It was found that Mesa did not correctly validate messages from the X server. A malicious X server could cause an application using Mesa to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2013-1993)

From Red Hat Security Advisory 2013:0898 :

Updated mesa packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

Mesa provides a 3D graphics API that is compatible with Open Graphics Library (OpenGL). It also provides hardware-accelerated drivers for many popular graphics chips.

It was discovered that Mesa incorrectly handled certain memory calculations. An attacker could use this flaw to cause an application to crash, or possibly execute arbitrary code. (CVE-2013-1872)

Ilja van Sprundel discovered that Mesa incorrectly handled certain memory calculations. An attacker could use this flaw to cause an application to crash, or possibly execute arbitrary code.
(CVE-2013-1993).

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

freedesktop.org reports :

Ilja van Sprundel, a security researcher with IOActive, has discovered a large number of issues in the way various X client libraries handle the responses they receive from servers, and has worked with X.Org's security team to analyze, confirm, and fix these issues.

Most of these issues stem from the client libraries trusting the server to send correct protocol data, and not verifying that the values will not overflow or cause other damage. Most of the time X clients & servers are run by the same user, with the server more privileged from the clients, so this is not a problem, but there are scenarios in which a privileged client can be connected to an unprivileged server, for instance, connecting a setuid X client (such as a screen lock program) to a virtual X server (such as Xvfb or Xephyr) which the user has modified to return invalid data, potentially allowing the user to escalate their privileges.

The vulnerabilities include :

Integer overflows calculating memory needs for replies.

Sign extension issues calculating memory needs for replies.

Buffer overflows due to not validating length or offset values in replies.

Integer overflows parsing user-specified files.

Unbounded recursion parsing user-specified files.

Memory corruption due to unchecked return values.

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2013:0897 advisory.

  - Mesa: Memory corruption (OOB read/write) on intel drivers (CVE-2013-1872)

  - Mesa: Multiple integer overflows leading to heap-based bufer overflows (CVE-2013-1993)

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

Ilja van Sprundel of IOActive discovered several security issues in multiple components of the X.org graphics stack and the related libraries: Various integer overflows, sign handling errors in integer conversions, buffer overflows, memory corruption and missing input sanitising may lead to privilege escalation or denial of service.
