The installed version of Firefox is earlier than 21.0 and is, therefore, potentially affected by multiple vulnerabilities :

  - Various memory safety issues exist. (CVE-2013-0801,     CVE-2013-1669)

  - It is possible to call a content level constructor that     allows for the constructor to have chrome privileged     access. (CVE-2013-1670)

  - An information leakage exists because the file input     control has access to the full path. (CVE-2013-1671)

  - A local privilege escalation issues exists in the     Mozilla Maintenance Service. (CVE-2013-1672)

  - The Mozilla Maintenance Service on Windows is vulnerable     to a previously fixed privilege escalation attack.  Note     that new installations of Firefox after version 12 are     not affected by this issue. (CVE-2013-1673,     CVE-2012-1942)

  - A use-after-free vulnerability exists when resizing     video while playing. (CVE-2013-1674)

  - Some 'DOMSVGZoomEvent' functions are used without being     properly initialized, which could lead to information     disclosure. (CVE-2013-1675)

  - Multiple memory corruption issues exist. (CVE-2013-1676,     CVE-2013-1677, CVE-2013-1678, CVE-2013-1679,     CVE-2013-1680, CVE-2013-1681)

Mozilla Firefox has been updated to the 17.0.7 ESR version, which fixes bugs and security fixes.

  - 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 2013-49)

    Gary Kwong, Jesse Ruderman, and Andrew McCreight     reported memory safety problems and crashes that affect     Firefox ESR 17, and Firefox 21. (CVE-2013-1682)

  - Security researcher Abhishek Arya (Inferno) of the     Google Chrome Security Team used the Address Sanitizer     tool to discover a series of use-after-free problems     rated critical as 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 additional     use-after-free and buffer overflow flaws in code     introduced during Firefox development. These were fixed     before general release. (MFSA 2013-50)

  - Heap-use-after-free in     mozilla::dom::HTMLMediaElement::LookupMediaElementURITab     le. (CVE-2013-1684)

  - Heap-use-after-free in nsIDocument::GetRootElement.
    (CVE-2013-1685)

  - Heap-use-after-free in mozilla::ResetDir.
    (CVE-2013-1686)

  - Security researcher Mariusz Mlynski reported that it is     possible to compile a user-defined function in the XBL     scope of a specific element and then trigger an event     within this scope to run code. In some circumstances,     when this code is run, it can access content protected     by System Only Wrappers (SOW) and chrome-privileged     pages. This could potentially lead to arbitrary code     execution. Additionally, Chrome Object Wrappers (COW)     can be bypassed by web content to access privileged     methods, leading to a cross-site scripting (XSS) attack     from privileged pages. (MFSA 2013-51 / CVE-2013-1687)

  - Security researcher Nils reported that specially crafted     web content using the onreadystatechange event and     reloading of pages could sometimes cause a crash when     unmapped memory is executed. This crash is potentially     exploitable. (MFSA 2013-53 / CVE-2013-1690)

  - Security researcher Johnathan Kuskos reported that     Firefox is sending data in the body of XMLHttpRequest     (XHR) HEAD requests, which goes against the XHR     specification. This can potentially be used for     Cross-Site Request Forgery (CSRF) attacks against sites     which do not distinguish between HEAD and POST requests.
    (MFSA 2013-54 / CVE-2013-1692)

  - Security researcher Paul Stone of Context Information     Security discovered that timing differences in the     processing of SVG format images with filters could allow     for pixel values to be read. This could potentially     allow for text values to be read across domains, leading     to information disclosure. (MFSA 2013-55 /     CVE-2013-1693)

  - Mozilla security researcher moz_bug_r_a4 reported that     XrayWrappers can be bypassed to call content-defined     toString and valueOf methods through DefaultValue. This     can lead to unexpected behavior when privileged code     acts on the incorrect values. (MFSA 2013-59 /     CVE-2013-1697)

  - 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 2013-30)

    Olli Pettay, Jesse Ruderman, Boris Zbarsky, Christian     Holler, Milan Sreckovic, and Joe Drew reported memory     safety problems and crashes that affect Firefox ESR 17,     and Firefox 19. (CVE-2013-0788)

  - Security researcher Abhishek Arya (Inferno) of the     Google Chrome Security Team used the Address Sanitizer     tool to discover an out-of-bounds write in Cairo     graphics library. When certain values are passed to it     during rendering, Cairo attempts to use negative     boundaries or sizes for boxes, leading to a potentially     exploitable crash in some instances. (MFSA 2013-31 /     CVE-2013-0800)

  - Security researcher Frederic Hoguin discovered that the     Mozilla Maintenance Service on Windows was vulnerable to     a buffer overflow. This system is used to update     software without invoking the User Account Control (UAC)     prompt. The Mozilla Maintenance Service is configured to     allow unprivileged users to start it with arbitrary     arguments. By manipulating the data passed in these     arguments, an attacker can execute arbitrary code with     the system privileges used by the service. This issue     requires local file system access to be exploitable.
    (MFSA 2013-32 / CVE-2013-0799)

  - Security researcher Ash reported an issue with the     Mozilla Updater. The Mozilla Updater can be made to load     a malicious local DLL file in a privileged context     through either the Mozilla Maintenance Service or     independently on systems that do not use the service.
    This occurs when the DLL file is placed in a specific     location on the local system before the Mozilla Updater     is run. Local file system access is necessary in order     for this issue to be exploitable. (MFSA 2013-34 /     CVE-2013-0797)

  - Security researcher miaubiz used the Address Sanitizer     tool to discover a crash in WebGL rendering when memory     is freed that has not previously been allocated. This     issue only affects Linux users who have Intel Mesa     graphics drivers. The resulting crash could be     potentially exploitable. (MFSA 2013-35 / CVE-2013-0796)

  - Security researcher Cody Crews reported a mechanism to     use the cloneNode method to bypass System Only Wrappers     (SOW) and clone a protected node. This allows violation     of the browser's same origin policy and could also lead     to privilege escalation and the execution of arbitrary     code. (MFSA 2013-36 / CVE-2013-0795)

  - Security researcher shutdown reported a method for     removing the origin indication on tab-modal dialog boxes     in combination with browser navigation. This could allow     an attacker's dialog to overlay a page and show another     site's content. This can be used for phishing by     allowing users to enter data into a modal prompt dialog     on an attacking, site while appearing to be from the     displayed site. (MFSA 2013-37 / CVE-2013-0794)

  - Security researcher Mariusz Mlynski reported a method to     use browser navigations through history to load an     arbitrary website with that page's baseURI property     pointing to another site instead of the seemingly loaded     one. The user will continue to see the incorrect site in     the addressbar of the browser. This allows for a     cross-site scripting (XSS) attack or the theft of data     through a phishing attack. (MFSA 2013-38 /     CVE-2013-0793)

  - Mozilla community member Tobias Schula reported that if     gfx.color_management.enablev4 preference is enabled     manually in about:config, some grayscale PNG images will     be rendered incorrectly and cause memory corruption     during PNG decoding when certain color profiles are in     use. A crafted PNG image could use this flaw to leak     data through rendered images drawing from random memory.
    By default, this preference is not enabled. (MFSA     2013-39 / CVE-2013-0792)

  - Mozilla community member Ambroz Bizjak reported an     out-of-bounds array read in the CERT_DecodeCertPackage     function of the Network Security Services (NSS) libary     when decoding a certificate. When this occurs, it will     lead to memory corruption and a non-exploitable crash.
    (MFSA 2013-40 / CVE-2013-0791)

  - 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 2013-43 / CVE-2013-1671)

  - Security researcher Seb Patane reported an issue with     the Mozilla Maintenance Service on Windows. This issue     allows unprivileged users to local privilege escalation     through the system privileges used by the service when     interacting with local malicious software. This allows     the user to bypass integrity checks leading to local     privilege escalation. Local file system access is     necessary in order for this issue to be exploitable and     it cannot be triggered through web content. (MFSA     2013-44 / CVE-2013-1672)

  - Security researcher Robert Kugler discovered that in     some instances the Mozilla Maintenance Service on     Windows will be vulnerable to some previously fixed     privilege escalation attacks that allowed for local     privilege escalation. This was caused by the Mozilla     Updater not updating Windows Registry entries for the     Mozilla Maintenance Service, which fixed the earlier     issues present if Firefox 12 had been installed. New     installations of Firefox after version 12 are not     affected by this issue. Local file system access is     necessary in order for this issue to be exploitable and     it cannot be triggered through web content. References:
