Assertion failure: ss->ssl3.hs.hashType == handshakehashunknown(CVE-2014-1495)

Versions of Mozilla Firefox ESR earlier than 24.4 are unpatched for a flaw that exists in the 'checkHandshake()' function in 'security/manager/ssl/src/nsNSSIOLayer.cpp'.  The issue is triggered as user-supplied input is not properly validated.  This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.

The installed version of Firefox ESR 24.x is a version prior to 24.4.
It is, therefore, potentially affected by the following vulnerabilities :

  - Memory issues exist that could lead to arbitrary code     execution. (CVE-2014-1493, CVE-2014-1494)

  - A flaw exists in the checkHandshake() function due to     improper validation of user-supplied input. An     unauthenticated, remote attacker can exploit this to     corrupt memory, resulting in the execution of arbitrary     code. (CVE-2014-1495)

  - An issue exists where extracted files for updates are     not read-only while updating.  An attacker may be able     to modify these extracted files resulting in privilege     escalation. (CVE-2014-1496)

  - An out-of-bounds read error exists when decoding WAV     format audio files that could lead to a denial of     service attack or information disclosure.
    (CVE-2014-1497)

  - An out-of-bounds read error exists when polygons are     rendered in 'MathML' that could lead to information     disclosure. (CVE-2014-1508)

  - A memory corruption issue exists in the Cairo graphics     library when rendering a PDF file that could lead to     arbitrary code execution or a denial of service attack.
    (CVE-2014-1509)

  - An issue exists in the SVG filters and the     feDisplacementMap element that could lead to     information disclosure via timing attacks.
    (CVE-2014-1505)

  - An issue exists that could allow malicious websites to     load chrome-privileged pages when JavaScript     implemented WebIDL calls the 'window.open()' function,     which could result in arbitrary code execution.
    (CVE-2014-1510)

  - An issue exists that could allow a malicious website to     bypass the pop-up blocker. (CVE-2014-1511)

  - A use-after-free memory issue exists in 'TypeObjects'     in the JavaScript engine during Garbage Collection     that could lead to arbitrary code execution.
    (CVE-2014-1512)

  - An out-of-bounds write error exists due to     'TypedArrayObject' improperly handling 'ArrayBuffer'     objects that could result in arbitrary code execution.
    (CVE-2014-1513)

  - An out-of-bounds write error exists when copying values     from one array to another that could result in arbitrary     code execution. (CVE-2014-1514)
