The version of Firefox ESR 31.x installed on the remote Mac OS X host is prior to 31.1. It is, therefore, affected by the following vulnerabilities :

  - Multiple memory safety flaws exist within the browser     engine. Exploiting these, an attacker can cause a denial     of service or execute arbitrary code. (CVE-2014-1553,     CVE-2014-1562)

  - A use-after-free vulnerability exists due to improper     cycle collection when processing animated SVG content.
    A remote attacker can exploit this to cause a denial of     service or execute arbitrary code. (CVE-2014-1563)

  - Memory is not properly initialized during GIF rendering.
    Using a specially crafted web script, a remote attacker     can exploit this to acquire sensitive information from     the process memory. (CVE-2014-1564)

  - The Web Audio API contains a flaw where audio timelines     are properly created. Using specially crafted API calls,     a remote attacker can exploit this to acquire sensitive     information from the process memory or cause a denial of     service. (CVE-2014-1565)

  - A use-after-free vulnerability exists due to improper     handling of text layout in directionality resolution.
    A remote attacker can exploit this to execute arbitrary     code. (CVE-2014-1567)

The version of Thunderbird 24.x installed on the remote Mac OS X host is a version prior to 24.8. It is, therefore, affected by the following vulnerabilities :

  - Multiple memory safety flaws exist within the browser     engine. Exploiting these, an attacker can cause a denial     of service or execute arbitrary code. (CVE-2014-1562)

  - A use-after-free vulnerability exists due to improper     handling of text layout in directionality resolution.
    A remote attacker can exploit this to execute arbitrary     code. (CVE-2014-1567)

Updated firefox packages that fix two security issues are now available for Red Hat Enterprise Linux 5, 6, and 7.

Red Hat Product Security has rated this update as having Critical 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.

Mozilla Firefox is an open source web browser. XULRunner provides the XUL Runtime environment for Mozilla Firefox.

Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2014-1562, CVE-2014-1567)

Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Jan de Mooij as the original reporter of CVE-2014-1562, and regenrecht as the original reporter of CVE-2014-1567.

For technical details regarding these flaws, refer to the Mozilla security advisories for Firefox 24.8.0 ESR. You can find a link to the Mozilla advisories in the References section of this erratum.

All Firefox users should upgrade to these updated packages, which contain Firefox version 24.8.0 ESR, which corrects these issues. After installing the update, Firefox must be restarted for the changes to take effect.

The remote host is affected by the vulnerability described in GLSA-201504-01 (Mozilla Products: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Firefox, Thunderbird,       and SeaMonkey. Please review the CVE identifiers referenced below for       details.
  Impact :

    A remote attacker could entice a user to view a specially crafted web       page or email, possibly resulting in execution of arbitrary code or a       Denial of Service condition. Furthermore, a remote attacker may be able       to perform Man-in-the-Middle attacks, obtain sensitive information, spoof       the address bar, conduct clickjacking attacks, bypass security       restrictions and protection mechanisms,  or have other unspecified       impact.
  Workaround :

    There are no known workarounds at this time.

Versions of Mozilla Firefox ESR prior to 24.8 are unpatched for the following vulnerabilities :

 - Use-after-free vulnerabilities -- when setting text direction, and when interacting with SVG content through the DOM -- which can be leveraged for arbitrary code execution (CVE-2014-1567, CVE-2014-1563)
 - Out-of-bounds read in the Web Audio audio timeline that can trigger a crash and potentially disclose memory content (CVE-2014-1565)
 - Incomplete memory initialization when rendering a malformed GIF image could expose that memory to scripts via web content using the '<canvas>' feature, resulting in information disclosure (CVE-2014-1564)
 - Other undisclosed memory issues that have since been patched (CVE-2014-1553, CVE-2014-1554, CVE-2014-1562)

Versions of Mozilla Firefox earlier than 32.0 are unpatched for the following vulnerabilities :

 - Use-after-free vulnerabilities -- when setting text direction, and when interacting with SVG content through the DOM -- which can be leveraged for arbitrary code execution (CVE-2014-1567, CVE-2014-1563)
 - Out-of-bounds read in the Web Audio audio timeline that can trigger a crash and potentially disclose memory content (CVE-2014-1565)
 - Incomplete memory initialization when rendering a malformed GIF image could expose that memory to scripts via web content using the '<canvas>' feature, resulting in information disclosure (CVE-2014-1564)
 - Other undisclosed memory issues that have since been patched (CVE-2014-1553, CVE-2014-1554, CVE-2014-1562)
