The Intel drivers in Mesa 8.0.x and 9.0.x allow context-dependent attackers to cause a denial of service (reachable assertion and crash) and possibly execute arbitrary code via vectors involving 3d graphics that trigger an out-of-bounds array access, related to the fs_visitor::remove_dead_constants function. NOTE: this issue might be related to CVE-2013-0796.

Mesa was updated to fix a security problem in the Intel drivers, where potentially remote attackers via 3D models could inject code.

(CVE-2013-1872 - i965: fix problem with constant out of bounds access (bnc #828007).)

The remote host is affected by the vulnerability described in GLSA-201404-06 (Mesa: Multiple vulnerabilities)

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

    A remote attacker could possibly execute       arbitrary code with the privileges of the process, or cause a Denial of       Service condition.
  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)

A memory corruption in the Mesa Intel drivers (OOB read/write) has been fixed. (CVE-2013-1872) This could have been potentially exploited by remote attackers who would have been able to inject 3d graphics into the attacked desktop.

From Red Hat Security Advisory 2013:0897 :

Updated mesa packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links 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.

All users of Mesa are advised to upgrade to these updated packages, which contain backported patches to correct these issues. All running applications linked against Mesa must be restarted for this update to take effect.

Updated mesa packages fix multiple vulnerabilities

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).

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.

It was discovered that applications using the mesa library, a free implementation of the OpenGL API, may crash or execute arbitrary code due to an out of bounds memory access in the library. This vulnerability only affects systems with Intel chipsets.

The oldstable distribution (squeeze) is not affected by this problem.

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.
