Use-after-free vulnerability in the FontTableRec destructor in Mozilla Firefox before 31.0, Firefox ESR 24.x before 24.7, and Thunderbird before 24.7 on Windows allows remote attackers to execute arbitrary code via crafted use of fonts in MathML content, leading to improper handling of a DirectWrite font-face object.

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.

The remote Solaris system is missing necessary patches to address security updates.

Mozilla Firefox has been updated to the 24.7ESR security release.

Security issues fixed in this release :

The version of Thunderbird installed on the remote host is a version prior to 31.0. It is, therefore, affected by the following vulnerabilities :

  - When a pair of NSSCertificate structures are added to a     trust domain and then one of them is removed during use,     a use-after-free error occurs which may cause the     application to crash. This crash is potentially     exploitable. (CVE-2014-1544)

  - There are multiple memory safety hazards within the     browser engine. These hazards may lead to memory     corruption vulnerabilities, which may allow attackers     to execute arbitrary code. (CVE-2014-1547,     CVE-2014-1548)

  - A buffer overflow exists when interacting with the Web     Audio buffer during playback due to an error with the     allocation of memory for the buffer. This may lead to     a potentially exploitable crash. (CVE-2014-1549)

  - A use-after-free exists in Web Audio due to the way     control messages are handled. This may lead to a     potentially exploitable crash. (CVE-2014-1550)

  - There is a potential use-after-free issue in     DirectWrite font handling. This may allow an attacker     to potentially execute arbitrary code within the context     of the user running the application. (CVE-2014-1551)

  - There is an issue with the IFRAME sandbox same-origin     access policy which allows sandboxed content to access     other content from the same origin without approval.
    This may lead to a same-origin-bypass vulnerability.
    (CVE-2014-1552)

  - Triggering the FireOnStateChange event has the     potential to crash the application. This may lead to     a use-after-free and an exploitable crash.
    (CVE-2014-1555)

  - When using the Cesium JavaScript library to generate     WebGL content, the application may crash. This crash     is potentially exploitable. (CVE-2014-1556)

  - There is a flaw in the Skia library when scaling images     of high quality. If the image data is discarded while     being processed, the library may crash. This crash     is potentially exploitable. (CVE-2014-1557)

  - There are multiple issues with using invalid     characters in various certificates. These invalid     characters may cause certificates to be parsed     incorrectly which may lead to the inability to use     valid SSL certificates. (CVE-2014-1558, CVE-2014-1559,     CVE-2014-1560)
