Updated firefox packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having critical security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Mozilla Firefox is an open source web browser. XULRunner provides the XUL Runtime environment for Mozilla Firefox.

Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2011-3101, CVE-2012-1937, CVE-2012-1938, CVE-2012-1939, CVE-2012-1940, CVE-2012-1941, CVE-2012-1946, CVE-2012-1947)

Note: CVE-2011-3101 only affected users of certain NVIDIA display drivers with graphics cards that have hardware acceleration enabled.

It was found that the Content Security Policy (CSP) implementation in Firefox no longer blocked Firefox inline event handlers. A remote attacker could use this flaw to possibly bypass a web application's intended restrictions, if that application relied on CSP to protect against flaws such as cross-site scripting (XSS). (CVE-2012-1944)

If a web server hosted HTML files that are stored on a Microsoft Windows share, or a Samba share, loading such files with Firefox could result in Windows shortcut files (.lnk) in the same share also being loaded. An attacker could use this flaw to view the contents of local files and directories on the victim's system. This issue also affected users opening HTML files from Microsoft Windows shares, or Samba shares, that are mounted on their systems. (CVE-2012-1945)

For technical details regarding these flaws, refer to the Mozilla security advisories for Firefox 10.0.5 ESR. You can find a link to the Mozilla advisories in the References section of this erratum.

All Firefox users should upgrade to these updated packages, which contain Firefox version 10.0.5 ESR, which corrects these issues. After installing the update, Firefox must be restarted for the changes to take effect.

The installed version of Firefox 10.0.x is potentially affected by the following security issues :

  - An error exists in the ASN.1 decoder when handling zero     length items that can lead to application crashes.
    (CVE-2012-0441)

  - Multiple memory corruption errors exist. (CVE-2012-1937,     CVE-2012-1939)

  - Two heap-based buffer overflows and one heap-based use-     after-free error exist and are potentially exploitable.
    (CVE-2012-1940, CVE-2012-1941, CVE-2012-1947)

  - The inline-script blocking feature of the 'Content     Security Policy' (CSP) does not properly block inline     event handlers. This error allows remote attackers to     more easily carry out cross-site scripting attacks.
    (CVE-2012-1944)

  - A use-after-free error exists related to replacing or     inserting a node into a web document. (CVE-2012-1946)

An updated thunderbird package that fixes multiple security issues is now available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having critical security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Mozilla Thunderbird is a standalone mail and newsgroup client.

Several flaws were found in the processing of malformed content.
Malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2011-3101, CVE-2012-1937, CVE-2012-1938, CVE-2012-1939, CVE-2012-1940, CVE-2012-1941, CVE-2012-1946, CVE-2012-1947)

Note: CVE-2011-3101 only affected users of certain NVIDIA display drivers with graphics cards that have hardware acceleration enabled.

It was found that the Content Security Policy (CSP) implementation in Thunderbird no longer blocked Thunderbird inline event handlers.
Malicious content could possibly bypass intended restrictions if that content relied on CSP to protect against flaws such as cross-site scripting (XSS). (CVE-2012-1944)

If a web server hosted content that is stored on a Microsoft Windows share, or a Samba share, loading such content with Thunderbird could result in Windows shortcut files (.lnk) in the same share also being loaded.

Note: None of the issues in this advisory can be exploited by a specially crafted HTML mail message as JavaScript is disabled by default for mail messages. They could be exploited another way in Thunderbird, for example, when viewing the full remote content of an RSS feed.

All Thunderbird users should upgrade to this updated package, which contains Thunderbird version 10.0.5 ESR, which corrects these issues.
After installing the update, Thunderbird must be restarted for the changes to take effect.

MozillaFirefox has been updated to 10.0.5ESR fixing various bugs and security issues.

  - 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 2012-34)

    In general these flaws cannot be exploited through email     in the Thunderbird and SeaMonkey products because     scripting is disabled, but are potentially a risk in     browser or browser-like contexts in those products.

  - Security researcher James Forshaw of Context Information     Security found two issues with the Mozilla updater and     the Mozilla updater service introduced in Firefox 12 for     Windows. The first issue allows Mozilla's updater to     load a local DLL file in a privileged context. The     updater can be called by the Updater Service or     independently on systems that do not use the service.
    The second of these issues allows for the updater     service to load an arbitrary local DLL file, which can     then be run with the same system privileges used by the     service. Both of these issues require local file system     access to be exploitable. (MFSA 2012-35)

    Possible Arbitrary Code Execution by Update Service     (CVE-2012-1942) Updater.exe loads wsock32.dll from     application directory. (CVE-2012-1943)

  - Security researcher Adam Barth found that inline event     handlers, such as onclick, were no longer blocked by     Content Security Policy's (CSP) inline-script blocking     feature. Web applications relying on this feature of CSP     to protect against cross-site scripting (XSS) were not     fully protected. (CVE-2012-1944). (MFSA 2012-36)

  - Security researcher Paul Stone reported an attack where     an HTML page hosted on a Windows share and then loaded     could then load Windows shortcut files (.lnk) in the     same share. These shortcut files could then link to     arbitrary locations on the local file system of the     individual loading the HTML page. That page could show     the contents of these linked files or directories from     the local file system in an iframe, causing information     disclosure. (MFSA 2012-37)

    This issue could potentially affect Linux machines with     samba shares enabled. (CVE-2012-1945)

  - Security researcher Arthur Gerkis used the Address     Sanitizer tool to find a use-after-free while     replacing/inserting a node in a document. This     use-after-free could possibly allow for remote code     execution. (CVE-2012-1946). (MFSA 2012-38)

  - Security researcher Kaspar Brand found a flaw in how the     Network Security Services (NSS) ASN.1 decoder handles     zero length items. Effects of this issue depend on the     field. One known symptom is an unexploitable crash in     handling OCSP responses. NSS also mishandles zero-length     basic constraints, assuming default values for some     types that should be rejected as malformed. These issues     have been addressed in NSS 3.13.4, which is now being     used by Mozilla. (CVE-2012-0441). (MFSA 2012-39)

  - Security researcher Abhishek Arya of Google used the     Address Sanitizer tool to uncover several issues: two     heap buffer overflow bugs and a use-after-free problem.
    The first heap buffer overflow was found in conversion     from unicode to native character sets when the function     fails. The use-after-free occurs in nsFrameList when     working with column layout with absolute positioning in     a container that changes size. The second buffer     overflow occurs in nsHTMLReflowState when a window is     resized on a page with nested columns and a combination     of absolute and relative positioning. All three of these     issues are potentially exploitable. (MFSA 2012-40)

    Heap-buffer-overflow in utf16_to_isolatin1     (CVE-2012-1947) Heap-use-after-free in     nsFrameList::FirstChild. (CVE-2012-1940)

    Heap-buffer-overflow in     nsHTMLReflowState::CalculateHypotheticalBox, with nested     multi-column, relative position, and absolute position.

  - A use-after-free error exists related to replacing or     inserting a node into a web document. (CVE-2012-1946)

Security issues were identified and fixed in mozilla firefox and thunderbird :

Heap-based buffer overflow in the utf16_to_isolatin1 function in Mozilla Firefox 4.x through 12.0, Firefox ESR 10.x before 10.0.5, Thunderbird 5.0 through 12.0, Thunderbird ESR 10.x before 10.0.5, and SeaMonkey before 2.10 allows remote attackers to execute arbitrary code via vectors that trigger a character-set conversion failure (CVE-2012-1947)

Use-after-free vulnerability in the nsFrameList::FirstChild function in Mozilla Firefox 4.x through 12.0, Firefox ESR 10.x before 10.0.5, Thunderbird 5.0 through 12.0, Thunderbird ESR 10.x before 10.0.5, and SeaMonkey before 2.10 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption and application crash) by changing the size of a container of absolutely positioned elements in a column (CVE-2012-1940).

Heap-based buffer overflow in the nsHTMLReflowState::CalculateHypotheticalBox function in Mozilla Firefox 4.x through 12.0, Firefox ESR 10.x before 10.0.5, Thunderbird 5.0 through 12.0, Thunderbird ESR 10.x before 10.0.5, and SeaMonkey before 2.10 allows remote attackers to execute arbitrary code by resizing a window displaying absolutely positioned and relatively positioned elements in nested columns (CVE-2012-1941).

Use-after-free vulnerability in the nsINode::ReplaceOrInsertBefore function in Mozilla Firefox 4.x through 12.0, Firefox ESR 10.x before 10.0.5, Thunderbird 5.0 through 12.0, Thunderbird ESR 10.x before 10.0.5, and SeaMonkey before 2.10 might allow remote attackers to execute arbitrary code via document changes involving replacement or insertion of a node (CVE-2012-1946).

Mozilla Firefox 4.x through 12.0, Firefox ESR 10.x before 10.0.5, Thunderbird 5.0 through 12.0, Thunderbird ESR 10.x before 10.0.5, and SeaMonkey before 2.10 allow local users to obtain sensitive information via an HTML document that loads a shortcut (aka .lnk) file for display within an IFRAME element, as demonstrated by a network share implemented by (1) Microsoft Windows or (2) Samba (CVE-2012-1945).

The Content Security Policy (CSP) implementation in Mozilla Firefox 4.x through 12.0, Firefox ESR 10.x before 10.0.5, Thunderbird 5.0 through 12.0, Thunderbird ESR 10.x before 10.0.5, and SeaMonkey before 2.10 does not block inline event handlers, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via a crafted HTML document (CVE-2012-1944).

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 13.0, Thunderbird before 13.0, and SeaMonkey before 2.10 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to (1) methodjit/ImmutableSync.cpp, (2) the JSObject::makeDenseArraySlow function in js/src/jsarray.cpp, and unknown other components (CVE-2012-1938).

jsinfer.cpp in Mozilla Firefox ESR 10.x before 10.0.5 and Thunderbird ESR 10.x before 10.0.5 does not properly determine data types, which allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via crafted JavaScript code (CVE-2012-1939).

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox 4.x through 12.0, Firefox ESR 10.x before 10.0.5, Thunderbird 5.0 through 12.0, Thunderbird ESR 10.x before 10.0.5, and SeaMonkey before 2.10 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors (CVE-2012-1937).

Ken Russell of Google reported a bug in NVIDIA graphics drivers that they needed to work around in the Chromium WebGL implementation.
Mozilla has done the same in Firefox 13 and ESR 10.0.5 (CVE-2011-3101).

The ASN.1 decoder in the QuickDER decoder in Mozilla Network Security Services (NSS) before 3.13.4, as used in Firefox 4.x through 12.0, Firefox ESR 10.x before 10.0.5, Thunderbird 5.0 through 12.0, Thunderbird ESR 10.x before 10.0.5, and SeaMonkey before 2.10, allows remote attackers to cause a denial of service (application crash) via a zero-length item, as demonstrated by (1) a zero-length basic constraint or (2) a zero-length field in an OCSP response (CVE-2012-0441). NOTE: This flaw was addressed earlier with the MDVA-2012:036 advisory.

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

Additionally the NSPR and the NSS packages has been upgraded to the latest versions which resolves various upstream bugs.

    Possible Arbitrary Code Execution by Update Service     (CVE-2012-1942) Updater.exe loads wsock32.dll from     application directory. (CVE-2012-1943)

  - Security researcher Adam Barth found that inline event     handlers, such as onclick, were no longer blocked by     Content Security Policy's (CSP) inline-script blocking     feature. Web applications relying on this feature of CSP     to protect against cross-site scripting (XSS) were not     fully protected. (CVE-2012-1944). (MFSA 2012-36)

  - Security researcher Paul Stone reported an attack where     an HTML page hosted on a Windows share and then loaded     could then load Windows shortcut files (.lnk) in the     same share. These shortcut files could then link to     arbitrary locations on the local file system of the     individual loading the HTML page. That page could show     the contents of these linked files or directories from     the local file system in an iframe, causing information     disclosure. (MFSA 2012-37)

    This issue could potentially affect Linux machines with     samba shares enabled. (CVE-2012-1945)

  - Security researcher Arthur Gerkis used the Address     Sanitizer tool to find a use-after-free while     replacing/inserting a node in a document. This     use-after-free could possibly allow for remote code     execution. (CVE-2012-1946). (MFSA 2012-38)

  - Security researcher Kaspar Brand found a flaw in how the     Network Security Services (NSS) ASN.1 decoder handles     zero length items. Effects of this issue depend on the     field. One known symptom is an unexploitable crash in     handling OCSP responses. NSS also mishandles zero-length     basic constraints, assuming default values for some     types that should be rejected as malformed. These issues     have been addressed in NSS 3.13.4, which is now being     used by Mozilla. (CVE-2012-0441). (MFSA 2012-39)

  - Security researcher Abhishek Arya of Google used the     Address Sanitizer tool to uncover several issues: two     heap buffer overflow bugs and a use-after-free problem.
    The first heap buffer overflow was found in conversion     from unicode to native character sets when the function     fails. The use-after-free occurs in nsFrameList when     working with column layout with absolute positioning in     a container that changes size. The second buffer     overflow occurs in nsHTMLReflowState when a window is     resized on a page with nested columns and a combination     of absolute and relative positioning. All three of these     issues are potentially exploitable. (MFSA 2012-40)

    Heap-buffer-overflow in utf16_to_isolatin1     (CVE-2012-1947) Heap-use-after-free in     nsFrameList::FirstChild. (CVE-2012-1940)

    Heap-buffer-overflow in     nsHTMLReflowState::CalculateHypotheticalBox, with nested     multi-column, relative position, and absolute position.
    (CVE-2012-1941)

Jesse Ruderman, Igor Bukanov, Bill McCloskey, Christian Holler, Andrew McCreight, Olli Pettay, Boris Zbarsky, and Brian Bondy discovered memory safety issues affecting Firefox. If the user were tricked into opening a specially crafted page, an attacker could possibly exploit these to cause a denial of service via application crash, or potentially execute code with the privileges of the user invoking Firefox. (CVE-2012-1937, CVE-2012-1938)

It was discovered that Mozilla's WebGL implementation exposed a bug in certain NVIDIA graphics drivers. The impact of this issue has not been disclosed at this time. (CVE-2011-3101)

Adam Barth discovered that certain inline event handlers were not being blocked properly by the Content Security Policy's (CSP) inline-script blocking feature. Web applications relying on this feature of CSP to protect against cross-site scripting (XSS) were not fully protected. 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-2012-1944)

Paul Stone discovered that a viewed HTML page hosted on a Windows or Samba share could load Windows shortcut files (.lnk) in the same share. These shortcut files could then link to arbitrary locations on the local file system of the individual loading the HTML page. An attacker could potentially use this vulnerability to show the contents of these linked files or directories in an iframe, resulting in information disclosure. (CVE-2012-1945)

Arthur Gerkis discovered a use-after-free vulnerability while replacing/inserting a node in a document. If the user were tricked into opening a specially crafted page, an attacker could possibly exploit this to cause a denial of service via application crash, or potentially execute code with the privileges of the user invoking Firefox. (CVE-2012-1946)

Kaspar Brand discovered a vulnerability in how the Network Security Services (NSS) ASN.1 decoder handles zero length items. If the user were tricked into opening a specially crafted page, an attacker could possibly exploit this to cause a denial of service via application crash. (CVE-2012-0441)

Abhishek Arya discovered two buffer overflow and one use-after-free vulnerabilities. If the user were tricked into opening a specially crafted page, an attacker could possibly exploit these to cause a denial of service via application crash, or potentially execute code with the privileges of the user invoking Firefox. (CVE-2012-1940, CVE-2012-1941, CVE-2012-1947).

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 Thunderbird is earlier than 13.0 and thus, is potentially affected by the following security issues :

  - An error exists in the ASN.1 decoder when handling zero     length items that can lead to application crashes.
    (CVE-2012-0441)

  - Multiple memory corruption errors exist. (CVE-2012-1937,     CVE-2012-1938)

  - Two heap-based buffer overflows and one heap-based use-     after-free error exist and are potentially exploitable.
    (CVE-2012-1940, CVE-2012-1941, CVE-2012-1947)

  - Two arbitrary DLL load issues exist related to the     application update and update service functionality.
    (CVE-2012-1942, CVE-2012-1943)

  - The inline-script blocking feature of the 'Content     Security Policy' (CSP) does not properly block inline     event handlers. This error allows remote attackers to     more easily carry out cross-site scripting attacks.
    (CVE-2012-1944)

  - A use-after-free error exists related to replacing or     inserting a node into a web document. (CVE-2012-1946)

  - An error exists related to the certificate warning page     that can allow 'clickjacking' thereby tricking a user     into accepting unintended certificates. (CVE-2012-1964)
