The remote host is affected by the vulnerability described in GLSA-201309-23 (Mozilla Products: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Mozilla 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. Further, a remote attacker could conduct XSS       attacks, spoof URLs, bypass address space layout randomization, conduct       clickjacking attacks, obtain potentially sensitive information, bypass       access restrictions, modify the local filesystem, or conduct other       unspecified attacks.
  Workaround :

    There is no known workaround at this time.

MozillaFirefox has been updated to the 17.0.4ESR release. Besides the major version update from the 10ESR stable release line to the 17ESR stable release line, this update brings critical security and bugfixes :

  - VUPEN Security, via TippingPoint's Zero Day Initiative,     reported a use-after-free within the HTML editor when     content script is run by the document.execCommand()     function while internal editor operations are occurring.
    This could allow for arbitrary code execution. (MFSA     2013-29 / CVE-2013-0787)

The Firefox 17.0.3ESR release also contains lots of security fixes :

  - Security researcher Abhishek Arya (Inferno) of the     Google Chrome Security Team used the Address Sanitizer     tool to discover a series of use-after-free, out of     bounds read, and buffer overflow problems rated as low     to critical security issues in shipped software. Some of     these issues are potentially exploitable, allowing for     remote code execution. We would also like to thank     Abhishek for reporting four additional use-after-free     and out of bounds write flaws introduced during Firefox     development that were fixed before general release.
    (MFSA 2013-28)

The following issues have been fixed in Firefox 19 and ESR 17.0.3 :

  - Heap-use-after-free in     nsOverflowContinuationTracker::Finish, with

    -moz-columns. (CVE-2013-0780)

  - Heap-buffer-overflow WRITE in     nsSaveAsCharset::DoCharsetConversion. (CVE-2013-0782)

  - Google security researcher Michal Zalewski reported an     issue where the browser displayed the content of a     proxy's 407 response if a user canceled the proxy's     authentication prompt. In this circumstance, the     addressbar will continue to show the requested site's     address, including HTTPS addresses that appear to be     secure. This spoofing of addresses can be used for     phishing attacks by fooling users into entering     credentials, for example. (MFSA 2013-27 / CVE-2013-0776)

  - Security researcher Nils reported a use-after-free in     nsImageLoadingContent when content script is executed.
    This could allow for arbitrary code execution. (MFSA     2013-26 / CVE-2013-0775)

  - Mozilla security researcher Frederik Braun discovered     that since Firefox 15 the file system location of the     active browser profile was available to JavaScript     workers. While not dangerous by itself, this could     potentially be combined with other vulnerabilities to     target the profile in an attack. (MFSA 2013-25 /     CVE-2013-0774)

  - Mozilla developer Bobby Holley discovered that it was     possible to bypass some protections in Chrome Object     Wrappers (COW) and System Only Wrappers (SOW), making     their prototypes mutable by web content. This could be     used leak information from chrome objects and possibly     allow for arbitrary code execution. (MFSA 2013-24 /     CVE-2013-0773)

  - Mozilla developer Boris Zbarsky reported that in some     circumstances a wrapped WebIDL object can be wrapped     multiple times, overwriting the existing wrapped state.
    This could lead to an exploitable condition in rare     cases. (MFSA 2013-23 / CVE-2013-0765)

  - Using the Address Sanitizer tool, security researcher     Atte Kettunen from OUSPG found an out-of-bounds read     while rendering GIF format images. This could cause a     non-exploitable crash and could also attempt to render     normally inaccesible data as part of the image. (MFSA     2013-22 / CVE-2013-0772)

  - Mozilla developers identified and fixed several memory     safety bugs in the browser engine used in Firefox and     other Mozilla-based products. Some of these bugs showed     evidence of memory corruption under certain     circumstances, and we presume that with enough effort at     least some of these could be exploited to run arbitrary     code. (MFSA 2013-21)

    Olli Pettay, Christoph Diehl, Gary Kwong, Jesse     Ruderman, Andrew McCreight, Joe Drew, and Wayne Mery     reported memory safety problems and crashes that affect     Firefox ESR 17, and Firefox 18.

  - Memory safety bugs fixed in Firefox ESR 17.0.3, and     Firefox 19. (CVE-2013-0783)

Mozilla Firefox has been updated to the 17.0.3ESR release.

Important: due to compatibility issues, the Beagle plug-in for MozillaFirefox is temporarily disabled by this update.

Besides the major version update from the 10ESR stable release line to the 17ESR stable release line, this update brings critical security and bugfixes :
