Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 27.0 and SeaMonkey before 2.24 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to the MPostWriteBarrier class in js/src/jit/MIR.h and stack alignment in js/src/jit/AsmJS.cpp in OdinMonkey, and unknown other vectors.

Versions of Mozilla Firefox ESR prior to 24.3 are prone to the following vulnerabilities :

 - Memory issues exist in the browser engine that could result in a denial of service or arbitrary code execution. (CVE-2014-1477, CVE-2014-1478)
 - An error exists related to System Only Wrappers (SOW) and the XML Binding Language (XBL) that could allow XUL content to be disclosed. (CVE-2014-1479)
 - An error exists related to the 'open file' dialog that could allow users to take unintended actions. (CVE-2014-1480)
 - An error exists related to the JavaScript engine and 'window' object handling that has unspecified impact. (CVE-2014-1481)
 - An error exists related to 'RasterImage' and image decoding that could allow application crashes and possibly arbitrary code execution. (CVE-2014-1482)
 - Errors exist related to IFrames, 'document.caretPositionFromPoint' and 'document.elementFromPoint' that could allow cross-origin information disclosure. (CVE-2014-1483)
 - An error exists related to the Content Security Policy (CSP) and XSLT stylesheets that could allow unintended script execution. (CVE-2014-1485)
 - A use-after-free error exists related to image handling and 'imgRequestProxy' that could allow application crashes and possibly arbitrary code execution. (CVE-2014-1486)
 - An error exists related to 'web workers' that could allow cross-origin information disclosure. (CVE-2014-1487)
 - An error exists related to 'web workers' and 'asm.js' that could allow application crashes and possibly arbitrary code execution. (CVE-2014-1488)
 - An error exists that could allow webpages to access activate content from the 'about:home' page that could lead to data loss. (CVE-2014-1489)
 - Errors exist related to the included Network Security Services (NSS) libraries, 'NewSessionTicket' handshakes and public Diffie-Hellman values that could allow application crashes and possibly arbitrary code execution. (CVE-2014-1490, CVE-2014-1491)

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.

Mozilla Firefox was updated to version 27. Mozilla SeaMonkey was updated to 2.24, fixing similar issues as Firefox 27. Mozilla Thunderbird was updated to 24.3.0, fixing similar issues as Firefox 27.

The Firefox 27 release brings TLS 1.2 support as a major security feature.

It also fixes following security issues :

  - MFSA 2014-01/CVE-2014-1477/CVE-2014-1478 Miscellaneous     memory safety hazards (rv:27.0 / rv:24.3)

  - MFSA 2014-02/CVE-2014-1479 (bmo#911864) Clone protected     content with XBL scopes

  - MFSA 2014-10/CVE-2014-1489 (bmo#959531) Firefox default     start page UI content invokable by script

  - MFSA 2014-11/CVE-2014-1488 (bmo#950604) Crash when using     web workers with asm.js

  - MFSA 2014-12/CVE-2014-1490/CVE-2014-1491 (bmo#934545,     bmo#930874, bmo#930857) NSS ticket handling issues

  - MFSA 2014-13/CVE-2014-1481(bmo#936056) Inconsistent     JavaScript handling of access to Window objects

Mozilla NSS was updated to 3.15.4 :

  - required for Firefox 27

  - regular CA root store update (1.96)

  - Reordered the cipher suites offered in SSL/TLS client     hello messages to match modern best practices.

  - Improved SSL/TLS false start. In addition to enabling     the SSL_ENABLE_FALSE_START option, an application must     now register a callback using the     SSL_SetCanFalseStartCallback function.

  - When false start is enabled, libssl will sometimes     return unencrypted, unauthenticated data from PR_Recv     (CVE-2013-1740, bmo#919877)

  - MFSA 2014-12/CVE-2014-1490/CVE-2014-1491 NSS ticket     handling issues New functionality

  - Implemented OCSP querying using the HTTP GET method,     which is the new default, and will fall back to the HTTP     POST method.

  - Implemented OCSP server functionality for testing     purposes (httpserv utility).

  - Support SHA-1 signatures with TLS 1.2 client     authentication.

  - Added the --empty-password command-line option to     certutil, to be used with -N: use an empty password when     creating a new database.

  - Added the -w command-line option to pp: don't wrap long     output lines.

USN-2102-1 fixed vulnerabilities in Firefox. The update introduced a regression which could make Firefox crash under some circumstances.
This update fixes the problem.
