The version of Firefox installed on the remote Mac OS X host is prior to 38.0. It is, therefore, affected by the following vulnerabilities :

  - Multiple memory corruption issues exist within the     browser engine. A remote attacker can exploit these to     corrupt memory and execute arbitrary code.
    (CVE-2015-2708, CVE-2015-2709)

  - A buffer overflow condition exists in SVGTextFrame.cpp     when rendering SVG graphics that are combined with     certain CSS properties due to improper validation of     user-supplied input. A remote attacker can exploit this     to cause a heap-based buffer overflow, resulting in the     execution of arbitrary code. (CVE-2015-2710)

  - A security bypass vulnerability exists due to the     referrer policy not being enforced in certain situations     when opening links (e.g. using the context menu or a     middle-clicks by mouse). A remote attacker can exploit     this to bypass intended policy settings. (CVE-2015-2711)

  - An out-of-bounds read and write issue exists in the     CheckHeapLengthCondition() function due to improper     JavaScript validation of heap lengths. A remote attacker     can exploit this, via a specially crafted web page, to     disclose memory contents. (CVE-2015-2712)

  - A use-after-free error exists due to improper processing     of text when vertical text is enabled. A remote attacker     can exploit this to dereference already freed memory.
    (CVE-2015-2713)

  - A use-after-free error exists in the     RegisterCurrentThread() function in nsThreadManager.cpp     due to a race condition related to media decoder threads     created during the shutdown process. A remote attacker     can exploit this to dereference already freed memory.
    (CVE-2015-2715)

  - A buffer overflow condition exists in the     XML_GetBuffer() function in xmlparse.c due to improper     validation of user-supplied input when handling     compressed XML content. An attacker can exploit this to     cause a buffer overflow, resulting in the execution of     arbitrary code. (CVE-2015-2716)

  - An integer overflow condition exists in the parseChunk()     function in MPEG4Extractor.cpp due to improper handling     of MP4 video metadata in chunks. A remote attacker can     exploit this, via specially crafted media content, to     cause a heap-based buffer overflow, resulting in the     execution of arbitrary code. (CVE-2015-2717)

  - A security bypass vulnerability exists in WebChannel.jsm     due to improper handling of message traffic. An     untrusted page hosting a trusted page within an iframe     can intercept webchannel responses for the trusted page.
    This allows a remote attacker, via a specially crafted     web page, to bypass origin restrictions, resulting in     the disclosure of sensitive information. (CVE-2015-2718)

  - Multiple integer overflow conditions exist in the     bundled libstagefright component due to improper     validation of user-supplied input when processing MPEG4     sample metadata. A remote attacker can exploit this, via     specially crafted media content, to execute arbitrary     code. (CVE-2015-4496)

The version of Firefox installed on the remote Windows host is prior to 38.0. It is, therefore, affected by the following vulnerabilities :

  - A privilege escalation vulnerability exists in the     Inter-process Communications (IPC) implementation due     to a failure to validate the identity of a listener     process. (CVE-2011-3079)

  - An issue exists in the Mozilla updater in which DLL     files in the current working directory or Windows     temporary directories will be loaded, allowing the     execution of arbitrary code. (CVE-2015-0833 /     CVE-2015-2720)

  - Multiple memory corruption issues exist within the     browser engine. A remote attacker can exploit these to     corrupt memory and execute arbitrary code.
    (CVE-2015-2708, CVE-2015-2709)

Changes in Mozilla NSS :

  - update to 3.18.1

  - Firefox target release 38

  - No new functionality is introduced in this release.
    Notable Changes :

  - The following CA certificate had the Websites and Code     Signing trust bits restored to their original state to     allow more time to develop a better transition strategy     for affected sites :

  - OU = Equifax Secure Certificate Authority

  - The following CA certificate was removed :

  - CN = e-Guven Kok Elektronik Sertifika Hizmet Saglayicisi

  - The following intermediate CA certificate has been added     as actively distrusted because it was mis-used to issue     certificates for domain names the holder did not own or     control :

  - CN=MCSHOLDING TEST, O=MCSHOLDING, C=EG

  - The version number of the updated root CA list has been     set to 2.4

  - update to 3.18

  - Firefox target release 38 New functionality :

  - When importing certificates and keys from a PKCS#12     source, it's now possible to override the nicknames,     prior to importing them into the NSS database, using new     API SEC_PKCS12DecoderRenameCertNicknames.

  - The tstclnt test utility program has new command-line     options

    -C, -D, -b and -R. Use -C one, two or three times to     print information about the certificates received from a     server, and information about the locally found and     trusted issuer certificates, to diagnose server side     configuration issues. It is possible to run tstclnt

The remote host is affected by the vulnerability described in GLSA-201605-06 (Mozilla Products: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Firefox, NSS, NSPR, and       Thunderbird. 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       impacts.
  Workaround :

    There is no known workaround at this time.
