USN-1548-1 fixed vulnerabilities in Firefox. The new package caused a regression in Private Browsing which could leak sites visited to the browser cache. This update fixes the problem.

Gary Kwong, Christian Holler, Jesse Ruderman, Steve Fink, Bob Clary, Andrew Sutherland, Jason Smith, John Schoenick, Vladimir Vukicevic and Daniel Holbert discovered memory safety issues affecting Firefox. If the user were tricked into opening a specially crafted page, an attacker could exploit these to cause a denial of service via application crash, or potentially execute code with the privileges of the user invoking Firefox. (CVE-2012-1970, CVE-2012-1971)

Abhishek Arya discovered multiple use-after-free vulnerabilities. If the user were tricked into opening a specially crafted page, an attacker could exploit these to cause a denial of service via application crash, or potentially execute code with the privileges of the user invoking Firefox. (CVE-2012-1972, CVE-2012-1973, CVE-2012-1974, CVE-2012-1975, CVE-2012-1976, CVE-2012-3956, CVE-2012-3957, CVE-2012-3958, CVE-2012-3959, CVE-2012-3960, CVE-2012-3961, CVE-2012-3962, CVE-2012-3963, CVE-2012-3964)

Mariusz Mlynsk discovered that it is possible to shadow the location object using Object.defineProperty. This could potentially result in a cross-site scripting (XSS) attack against plugins. With cross-site scripting vulnerabilities, if a user were tricked into viewing a specially crafted page, a remote attacker could exploit this to modify the contents or steal confidential data within the same domain.
(CVE-2012-1956)

Mariusz Mlynski discovered an escalation of privilege vulnerability through about:newtab. This could possibly lead to potentially code execution with the privileges of the user invoking Firefox. (CVE-2012-3965)

Frederic Hoguin discovered that bitmap format images with a negative height could potentially result in memory corruption. If the user were tricked into opening a specially crafted image, an attacker could exploit this to cause a denial of service via application crash, or potentially execute code with the privileges of the user invoking Firefox. (CVE-2012-3966)

It was discovered that Firefox's WebGL implementation was vulnerable to multiple memory safety issues. If the user were tricked into opening a specially crafted page, an attacker could exploit these to cause a denial of service via application crash, or potentially execute code with the privileges of the user invoking Firefox. (CVE-2012-3967, CVE-2012-3968)

Arthur Gerkis discovered multiple memory safety issues in Firefox's Scalable Vector Graphics (SVG) implementation. If the user were tricked into opening a specially crafted image, an attacker could exploit these to cause a denial of service via application crash, or potentially execute code with the privileges of the user invoking Firefox.
(CVE-2012-3969, CVE-2012-3970)

Christoph Diehl discovered multiple memory safety issues in the bundled Graphite 2 library. If the user were tricked into opening a specially crafted page, an attacker could exploit these to cause a denial of service via application crash, or potentially execute code with the privileges of the user invoking Firefox. (CVE-2012-3971)

Nicolas Gregoire discovered an out-of-bounds read in the format-number feature of XSLT. This could potentially cause inaccurate formatting of numbers and information leakage.
(CVE-2012-3972)

Mark Goodwin discovered that under certain circumstances, Firefox's developer tools could allow remote debugging even when disabled. (CVE-2012-3973)

It was discovered that when the DOMParser is used to parse text/html data in a Firefox extension, linked resources within this HTML data will be loaded. If the data being parsed in the extension is untrusted, it could lead to information leakage and potentially be combined with other attacks to become exploitable. (CVE-2012-3975)

Mark Poticha discovered that under certain circumstances incorrect SSL certificate information can be displayed on the addressbar, showing the SSL data for a previous site while another has been loaded. This could potentially be used for phishing attacks. (CVE-2012-3976)

It was discovered that, in some instances, certain security checks in the location object could be bypassed. This could allow for the loading of restricted content and can potentially be combined with other issues to become exploitable. (CVE-2012-3978)

Colby Russell discovered that eval in the web console can execute injected code with chrome privileges, leading to the running of malicious code in a privileged context. If the user were tricked into opening a specially crafted page, an attacker could exploit this to cause a denial of service via application crash, or potentially execute code with the privileges of the user invoking Firefox. (CVE-2012-3980).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The installed version of Firefox is earlier than 15.0 and thus, is potentially affected by the following security issues :

  - An error exists related to 'Object.defineProperty'     and the location object that could allow cross-site     scripting attacks. (CVE-2012-1956)

  - Unspecified memory safety issues exist. (CVE-2012-1970,     CVE-2012-1971)

  - Multiple use-after-free errors exist. (CVE-2012-1972,     CVE-2012-1973, CVE-2012-1974, CVE-2012-1975,     CVE-2012-1976, CVE-2012-3956, CVE-2012-3957,     CVE-2012-3958, CVE-2012-3959, CVE-2012-3960,     CVE-2012-3961, CVE-2012-3962, CVE-2012-3963,     CVE-2012-3964)

  - An error exists related to 'about:newtab' and the     browser's history. This error can allow a newly opened     tab to further open a new window and navigate to the     privileged 'about:newtab' page leading to possible     privilege escalation. (CVE-2012-3965)

  - An error exists related to bitmap (BMP) and icon (ICO)     file decoding that can lead to memory corruption     causing application crashes and potentially arbitrary     code execution. (CVE-2012-3966)

  - A use-after-free error exists related to WebGL shaders.
    (CVE-2012-3968)

  - A buffer overflow exists related to SVG filters.

    (CVE-2012-3971)

  - An XSLT out-of-bounds read error exists related to     'format-number'. (CVE-2012-3972)

  - Remote debugging is possible even when disabled and the     'HTTPMonitor' extension is enabled. (CVE-2012-3973)

  - The DOM parser can unintentionally load linked     resources in extensions. (CVE-2012-3975)

  - Incorrect SSL certificate information can be displayed     in the address bar when two 'onLocationChange' events     fire out of order. (CVE-2012-3976)

  - Security checks related to location objects can be     bypassed if crafted calls are made to the browser     chrome code. (CVE-2012-3978)

  - Calling 'eval' in the web console can allow injected     code to be executed with browser chrome privileges.
    (CVE-2012-3980)

  - SPDY's request header compression leads to information     leakage, which can allow private data such as session     cookies to be extracted, even over an SSL connection.
    (CVE-2012-4930)

Security issues were identified and fixed in mozilla firefox :

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 (CVE-2012-1971).

Security researcher Abhishek Arya (Inferno) of Google Chrome Security Team discovered a series of use-after-free issues using the Address Sanitizer tool. Many of these issues are potentially exploitable, allowing for remote code execution (CVE-2012-1972, CVE-2012-1973, CVE-2012-1974, CVE-2012-1975, CVE-2012-1976, CVE-2012-3956, CVE-2012-3957, CVE-2012-3958, CVE-2012-3959, CVE-2012-3960, CVE-2012-3961, CVE-2012-3962, CVE-2012-3963, CVE-2012-3964).

Security researcher Mariusz Mlynski reported that it is possible to shadow the location object using Object.defineProperty. This could be used to confuse the current location to plugins, allowing for possible cross-site scripting (XSS) attacks (CVE-2012-1956).

Security researcher Mariusz Mlynski reported that when a page opens a new tab, a subsequent window can then be opened that can be navigated to about:newtab, a chrome privileged page. Once about:newtab is loaded, the special context can potentially be used to escalate privilege, allowing for arbitrary code execution on the local system in a maliciously crafted attack (CVE-2012-3965).

Security researcher Frederic Hoguin reported two related issues with the decoding of bitmap (.BMP) format images embedded in icon (.ICO) format files. When processing a negative height header value for the bitmap image, a memory corruption can be induced, allowing an attacker to write random memory and cause a crash. This crash may be potentially exploitable (CVE-2012-3966).

Security researcher miaubiz used the Address Sanitizer tool to discover two WebGL issues. The first issue is a use-after-free when WebGL shaders are called after being destroyed. The second issue exposes a problem with Mesa drivers on Linux, leading to a potentially exploitable crash (CVE-2012-3968, CVE-2012-3967).

Security researcher Arthur Gerkis used the Address Sanitizer tool to find two issues involving Scalable Vector Graphics (SVG) files. The first issue is a buffer overflow in Gecko's SVG filter code when the sum of two values is too large to be stored as a signed 32-bit integer, causing the function to write past the end of an array. The second issue is a use-after-free when an element with a requiredFeatures attribute is moved between documents. In that situation, the internal representation of the requiredFeatures value could be freed prematurely. Both issues are potentially exploitable (CVE-2012-3969, CVE-2012-3970).

Using the Address Sanitizer tool, Mozilla security researcher Christoph Diehl discovered two memory corruption issues involving the Graphite 2 library used in Mozilla products. Both of these issues can cause a potentially exploitable crash. These problems were fixed in the Graphite 2 library, which has been updated for Mozilla products (CVE-2012-3971).

Security research Nicolas Gregoire used the Address Sanitizer tool to discover an out-of-bounds read in the format-number feature of XSLT, which can cause inaccurate formatting of numbers and information leakage. This is not directly exploitable (CVE-2012-3972).

Mozilla security researcher Mark Goodwin discovered an issue with the Firefox developer tools' debugger. If remote debugging is disabled, but the experimental HTTPMonitor extension has been installed and enabled, a remote user can connect to and use the remote debugging service through the port used by HTTPMonitor. A remote-enabled flag has been added to resolve this problem and close the port unless debugging is explicitly enabled (CVE-2012-3973).

Security researcher Masato Kinugawa reported that if a crafted executable is placed in the root partition on a Windows file system, the Firefox and Thunderbird installer will launch this program after a standard installation instead of Firefox or Thunderbird, running this program with the user's privileges (CVE-2012-3974).

Security researcher vsemozhetbyt reported that when the DOMParser is used to parse text/html data in a Firefox extension, linked resources within this HTML data will be loaded. If the data being parsed in the extension is untrusted, it could lead to information leakage and can potentially be combined with other attacks to become exploitable (CVE-2012-3975).

Security researcher Mark Poticha reported an issue where incorrect SSL certificate information can be displayed on the addressbar, showing the SSL data for a previous site while another has been loaded. This is caused by two onLocationChange events being fired out of the expected order, leading to the displayed certificate data to not be updated. This can be used for phishing attacks by allowing the user to input form or other data on a newer, attacking, site while the credentials of an older site appear on the addressbar (CVE-2012-3976).

Mozilla security researcher moz_bug_r_a4 reported that certain security checks in the location object can be bypassed if chrome code is called content in a specific manner. This allowed for the loading of restricted content. This can be combined with other issues to become potentially exploitable (CVE-2012-3978).

Security researcher Colby Russell discovered that eval in the web console can execute injected code with chrome privileges, leading to the running of malicious code in a privileged context. This allows for arbitrary code execution through a malicious web page if the web console is invoked by the user (CVE-2012-3980).

The mozilla firefox packages has been upgraded to the latest versions which is unaffected by these security flaws.

Additionally the sqlite3 packages has been upgraded to the 3.7.13 version as firefox 15.0 requires the 3.7.12.1+ version.

  - use after free, webgl fragment shader deleted by     accessor. (CVE-2012-3968)

  - stack scribbling with 4-byte values choosable among a     few values, when using more than 16 sampler uniforms, on     Mesa, with all drivers CVE-2012-3967

  - Security researcher Arthur Gerkis used the Address     Sanitizer tool to find two issues involving Scalable     Vector Graphics (SVG) files. The first issue is a buffer     overflow in Gecko's SVG filter code when the sum of two     values is too large to be stored as a signed 32-bit     integer, causing the function to write past the end of     an array. The second issue is a use-after-free when an     element with a 'requiredFeatures' attribute is moved     between documents. In that situation, the internal     representation of the 'requiredFeatures' value could be     freed prematurely. Both issues are potentially     exploitable. (MFSA 2012-63)

  - Heap-buffer-overflow in     nsSVGFEMorphologyElement::Filter. (CVE-2012-3969)

  - Heap-use-after-free in nsTArray_base::Length().
    (CVE-2012-3970)

  - Using the Address Sanitizer tool, Mozilla security     researcher Christoph Diehl discovered two memory     corruption issues involving the Graphite 2 library used     in Mozilla products. Both of these issues can cause a     potentially exploitable crash. These problems were fixed     in the Graphite 2 library, which has been updated for     Mozilla products. (MFSA 2012-64 / CVE-2012-3971)

  - Security research Nicolas Gregoire used the Address     Sanitizer tool to discover an out-of-bounds read in the     format-number feature of XSLT, which can cause     inaccurate formatting of numbers and information     leakage. This is not directly exploitable. (MFSA 2012-65     / CVE-2012-3972)

  - Mozilla security researcher Mark Goodwin discovered an     issue with the Firefox developer tools' debugger. If     remote debugging is disabled, but the experimental     HTTPMonitor extension has been installed and enabled, a     remote user can connect to and use the remote debugging     service through the port used by HTTPMonitor. A     remote-enabled flag has been added to resolve this     problem and close the port unless debugging is     explicitly enabled. (MFSA 2012-66 / CVE-2012-3973)

  - Security researcher Masato Kinugawa reported that if a     crafted executable is placed in the root partition on a     Windows file system, the Firefox and Thunderbird     installer will launch this program after a standard     installation instead of Firefox or Thunderbird, running     this program with the user's privileges. (MFSA 2012-67 /     CVE-2012-3974)

  - Security researcher vsemozhetbyt reported that when the     DOMParser is used to parse text/html data in a Firefox     extension, linked resources within this HTML data will     be loaded. If the data being parsed in the extension is     untrusted, it could lead to information leakage and can     potentially be combined with other attacks to become     exploitable. (MFSA 2012-68 / CVE-2012-3975)

  - Security researcher Mark Poticha reported an issue where     incorrect SSL certificate information can be displayed     on the addressbar, showing the SSL data for a previous     site while another has been loaded. This is caused by     two onLocationChange events being fired out of the     expected order, leading to the displayed certificate     data to not be updated. This can be used for phishing     attacks by allowing the user to input form or other data     on a newer, attacking, site while the credentials of an     older site appear on the addressbar. (MFSA 2012-69 /     CVE-2012-3976)

  - Mozilla security researcher moz_bug_r_a4 reported that     certain security checks in the location object can be     bypassed if chrome code is called content in a specific     manner. This allowed for the loading of restricted     content. This can be combined with other issues to     become potentially exploitable. (MFSA 2012-70 /     CVE-2012-3978)

  - Mozilla developer Blake Kaplan reported that
    __android_log_print is called insecurely in places. If a     malicious web page used a dump() statement with a     specially crafted string, it can trigger a potentially     exploitable crash. (MFSA 2012-71 / CVE-2012-3979)

    This vulnerability only affects Firefox for Android.

  - Security researcher Colby Russell discovered that eval     in the web console can execute injected code with chrome     privileges, leading to the running of malicious code in     a privileged context. This allows for arbitrary code     execution through a malicious web page if the web     console is invoked by the user. (MFSA 2012-72 /     CVE-2012-3980)

The remote host is affected by the vulnerability described in GLSA-201301-01 (Mozilla Products: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Mozilla Firefox,       Thunderbird, SeaMonkey, NSS, GNU IceCat, and XULRunner. 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,       bypass restrictions and protection mechanisms, force file downloads,       conduct XML injection attacks, conduct XSS attacks, bypass the Same       Origin Policy, spoof URL&rsquo;s for phishing attacks, trigger a vertical       scroll, spoof the location bar, spoof an SSL indicator, modify the       browser&rsquo;s font, conduct clickjacking attacks, or have other unspecified       impact.
    A local attacker could gain escalated privileges, obtain sensitive       information, or replace an arbitrary downloaded file.
  Workaround :

    There is no known workaround at this time.
