| Description: |
Mozilla Firefox has been updated to the 17.0.7 ESR version, which fixes bugs and security fixes.
*
MFSA 2013-49: 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.
* Gary Kwong, Jesse Ruderman, and Andrew McCreight reported memory safety problems and crashes that affect Firefox ESR 17, and Firefox 21. (CVE-2013-1682)
*
MFSA 2013-50: 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.
o Heap-use-after-free in mozilla::dom::HTMLMediaElement::LookupMediaElementURITable (CVE-2013-1684) o Heap-use-after-free in nsIDocument::GetRootElement (CVE-2013-1685) o Heap-use-after-free in mozilla::ResetDir (CVE-2013-1686) *
MFSA 2013-51 / CVE-2013-1687: 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 2013-53 / CVE-2013-1690: 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 2013-54 / CVE-2013-1692: Security researcher Johnathan Kuskos reported that Firefox is sending data in the body of XMLHttpRequest (XHR) HEAD requests, which goes agains 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 2013-55 / CVE-2013-1693: 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 2013-59 / CVE-2013-1697: 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 2013-30: 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.
* 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)
*
MFSA 2013-31 / CVE-2013-0800: 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 2013-32 / CVE-2013-0799: 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 2013-34 / CVE-2013-0797: 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 2013-35 / CVE-2013-0796: 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 2013-36 / CVE-2013-0795: 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 2013-37 / CVE-2013-0794: 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 2013-38 / CVE-2013-0793: 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 2013-39 / CVE-2013-0792: 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 2013-40 / CVE-2013-0791: 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 2013-41: 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 2013-42 / CVE-2013-1670: Security researcher Cody Crews reported a method to call a content level constructor that allows for this constructor to have chrome privileged accesss. This affects chrome object wrappers (COW) and allows for write actions on objects when only read actions should be allowed. This can lead to cross-site scripting (XSS) attacks.
*
MFSA 2013-43 / CVE-2013-1671: Mozilla security researcher moz_bug_r_a4 reported a mechanism to exploit the control when set to the file type in order to get the full path. This can lead to information leakage and could be combined with other exploits to target attacks on the local file system.
*
MFSA 2013-44 / CVE-2013-1672: 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 2013-45: 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.

MFSA 2013-46 / CVE-2013-1674: Security researcher Nils reported a use-after-free when resizing video while playing. This could allow for arbitrary code execution.
*
MFSA 2013-47 / CVE-2013-1675: Mozilla community member Ms2ger discovered that some DOMSVGZoomEvent functions are used without being properly initialized, causing uninitialized memory to be used when they are called by web content. This could lead to a information leakage to sites depending on the contents of this uninitialized memory.
*
MFSA 2013-48: 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 invalid write problems rated as moderate to 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 flaws in dir=auto code introduced during Firefox development. These were fixed before general release.
