From Red Hat Security Advisory 2012:0516 :

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.

A flaw was found in Sanitiser for OpenType (OTS), used by Thunderbird to help prevent potential exploits in malformed OpenType fonts.
Malicious content could cause Thunderbird to crash or, under certain conditions, possibly execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2011-3062)

Malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2012-0467, CVE-2012-0468, CVE-2012-0469)

Content containing a malicious Scalable Vector Graphics (SVG) image file could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird.
(CVE-2012-0470)

A flaw was found in the way Thunderbird used its embedded Cairo library to render certain fonts. Malicious content could cause Thunderbird to crash or, under certain conditions, possibly execute arbitrary code with the privileges of the user running Thunderbird.
(CVE-2012-0472)

A flaw was found in the way Thunderbird rendered certain images using WebGL. Malicious content could cause Thunderbird to crash or, under certain conditions, possibly execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2012-0478)

A cross-site scripting (XSS) flaw was found in the way Thunderbird handled certain multibyte character sets. Malicious content could cause Thunderbird to run JavaScript code with the permissions of different content. (CVE-2012-0471)

A flaw was found in the way Thunderbird rendered certain graphics using WebGL. Malicious content could cause Thunderbird to crash.
(CVE-2012-0473)

A flaw in the built-in feed reader in Thunderbird allowed the Website field to display the address of different content than the content the user was visiting. An attacker could use this flaw to conceal a malicious URL, possibly tricking a user into believing they are viewing a trusted site, or allowing scripts to be loaded from the attacker's site, possibly leading to cross-site scripting (XSS) attacks. (CVE-2012-0474)

A flaw was found in the way Thunderbird decoded the ISO-2022-KR and ISO-2022-CN character sets. Malicious content could cause Thunderbird to run JavaScript code with the permissions of different content.
(CVE-2012-0477)

A flaw was found in the way the built-in feed reader in Thunderbird handled RSS and Atom feeds. Invalid RSS or Atom content loaded over HTTPS caused Thunderbird to display the address of said content, but not the content. The previous content continued to be displayed. An attacker could use this flaw to perform phishing attacks, or trick users into thinking they are visiting the site reported by the Website field, when the page is actually content controlled by an attacker.
(CVE-2012-0479)

Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Mateusz Jurczyk of the Google Security Team as the original reporter of CVE-2011-3062; Aki Helin from OUSPG as the original reporter of CVE-2012-0469; Atte Kettunen from OUSPG as the original reporter of CVE-2012-0470; wushi of team509 via iDefense as the original reporter of CVE-2012-0472; Ms2ger as the original reporter of CVE-2012-0478; Anne van Kesteren of Opera Software as the original reporter of CVE-2012-0471; Matias Juntunen as the original reporter of CVE-2012-0473; Jordi Chancel and Eddy Bordi, and Chris McGowen as the original reporters of CVE-2012-0474; Masato Kinugawa as the original reporter of CVE-2012-0477; and Jeroen van der Gun as the original reporter of CVE-2012-0479.

Note: All issues except CVE-2012-0470, CVE-2012-0472, and CVE-2011-3062 cannot be exploited by a specially crafted HTML mail message as JavaScript is disabled by default for mail messages. It could be exploited another way in Thunderbird, for example, when viewing the full remote content of an RSS feed.

For technical details regarding these flaws, refer to the Mozilla security advisories for Firefox 10.0.4 ESR. You can find a link to the Mozilla advisories in the References section of this erratum.

MozillaFirefox was updated to the 10.0.4 ESR release to fix 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 2012-20)

    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.

o

Christian Holler a reported memory safety and security problem affecting Firefox 11. (CVE-2012-0468)

o

Bob Clary, Christian Holler, Brian Hackett, Bobby Holley, Gary Kwong, Hilary Hall, Honza Bambas, Jesse Ruderman, Julian Seward, and Olli Pettay reported memory safety problems and crashes that affect Firefox ESR and Firefox 11.
(CVE-2012-0467)

  - Using the Address Sanitizer tool, security researcher     Aki Helin from OUSPG found that IDBKeyRange of indexedDB     remains in the XPConnect hashtable instead of being     unlinked before being destroyed. When it is destroyed,     this causes a use-after-free, which is potentially     exploitable. (MFSA 2012-22 / CVE-2012-0469)

  - Using the Address Sanitizer tool, security researcher     Atte Kettunen from OUSPG found a heap corruption in     gfxImageSurface which allows for invalid frees and     possible remote code execution. This happens due to     float error, resulting from graphics values being passed     through different number systems. (MFSA 2012-23 /     CVE-2012-0470)

  - Anne van Kesteren of Opera Software found a multi-octet     encoding issue where certain octets will destroy the     following octets in the processing of some multibyte     character sets. This can leave users vulnerable to     cross-site scripting (XSS) attacks on maliciously     crafted web pages. (MFSA 2012-24 / CVE-2012-0471)

  - Security research firm iDefense reported that researcher     wushi of team509 discovered a memory corruption on     Windows Vista and Windows 7 systems with hardware     acceleration disabled or using incompatible video     drivers. This is created by using cairo-dwrite to     attempt to render fonts on an unsupported code path.
    This corruption causes a potentially exploitable crash     on affected systems. (MFSA 2012-25 / CVE-2012-0472)

  - Mozilla community member Matias Juntunen discovered an     error in WebGLBuffer where FindMaxElementInSubArray     receives wrong template arguments from     FindMaxUshortElement. This bug causes maximum index to     be computed incorrectly within WebGL.drawElements,     allowing the reading of illegal video memory. (MFSA     2012-26 / CVE-2012-0473)

  - Security researchers Jordi Chancel and Eddy Bordi     reported that they could short-circuit page loads to     show the address of a different site than what is loaded     in the window in the addressbar. Security researcher     Chris McGowen independently reported the same flaw, and     further demonstrated that this could lead to loading     scripts from the attacker's site, leaving users     vulnerable to cross-site scripting (XSS) attacks. (MFSA     2012-27 / CVE-2012-0474)

  - Security researcher Simone Fabiano reported that if a     cross-site XHR or WebSocket is opened on a web server on     a non-standard port for web traffic while using an IPv6     address, the browser will send an ambiguous origin     headers if the IPv6 address contains at least 2     consecutive 16-bit fields of zeroes. If there is an     origin access control list that uses IPv6 literals, this     issue could be used to bypass these access controls on     the server. (MFSA 2012-28 / CVE-2012-0475)

  - Security researcher Masato Kinugawa found that during     the decoding of ISO-2022-KR and ISO-2022-CN character     sets, characters near 1024 bytes are treated     incorrectly, either doubling or deleting bytes. On     certain pages it might be possible for an attacker to     pad the output of the page such that these errors fall     in the right place to affect the structure of the page,     allowing for cross-site script (XSS) injection. (MFSA     2012-29 / CVE-2012-0477)

  - Mozilla community member Ms2ger found an image rendering     issue with WebGL when texImage2D uses use     JSVAL_TO_OBJECT on arbitrary objects. This can lead to a     crash on a maliciously crafted web page. While there is     no evidence that this is directly exploitable, there is     a possibility of remote code execution. (MFSA 2012-30 /     CVE-2012-0478)

  - Mateusz Jurczyk of the Google Security Team discovered     an off-by-one error in the OpenType Sanitizer using the     Address Sanitizer tool. This can lead to an     out-of-bounds read and execution of an uninitialized     function pointer during parsing and possible remote code     execution. (MFSA 2012-31 / CVE-2011-3062)

  - Security researcher Daniel Divricean reported that a     defect in the error handling of JavaScript errors can     leak the file names and location of JavaScript files on     a server, leading to inadvertent information disclosure     and a vector for further attacks. (MFSA 2012-32 /     CVE-2011-1187)

  - Security researcher Jeroen van der Gun reported that if     RSS or Atom XML invalid content is loaded over HTTPS,     the addressbar updates to display the new location of     the loaded resource, including SSL indicators, while the     main window still displays the previously loaded     content. This allows for phishing attacks where a     malicious page can spoof the identify of another     seemingly secure site. (MFSA 2012-33 / CVE-2012-0479)

(CVE-2012-0472)

A flaw was found in the way Thunderbird rendered certain images using WebGL. Malicious content could cause Thunderbird to crash or, under certain conditions, possibly execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2012-0478)

A cross-site scripting (XSS) flaw was found in the way Thunderbird handled certain multibyte character sets. Malicious content could cause Thunderbird to run JavaScript code with the permissions of different content. (CVE-2012-0471)

A flaw was found in the way Thunderbird rendered certain graphics using WebGL. Malicious content could cause Thunderbird to crash.
(CVE-2012-0473)

A flaw in the built-in feed reader in Thunderbird allowed the Website field to display the address of different content than the content the user was visiting. An attacker could use this flaw to conceal a malicious URL, possibly tricking a user into believing they are viewing a trusted site, or allowing scripts to be loaded from the attacker's site, possibly leading to cross-site scripting (XSS) attacks. (CVE-2012-0474)

A flaw was found in the way Thunderbird decoded the ISO-2022-KR and ISO-2022-CN character sets. Malicious content could cause Thunderbird to run JavaScript code with the permissions of different content.
(CVE-2012-0477)

A flaw was found in the way the built-in feed reader in Thunderbird handled RSS and Atom feeds. Invalid RSS or Atom content loaded over HTTPS caused Thunderbird to display the address of said content, but not the content. The previous content continued to be displayed. An attacker could use this flaw to perform phishing attacks, or trick users into thinking they are visiting the site reported by the Website field, when the page is actually content controlled by an attacker.
(CVE-2012-0479)

Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Mateusz Jurczyk of the Google Security Team as the original reporter of CVE-2011-3062; Aki Helin from OUSPG as the original reporter of CVE-2012-0469; Atte Kettunen from OUSPG as the original reporter of CVE-2012-0470; wushi of team509 via iDefense as the original reporter of CVE-2012-0472; Ms2ger as the original reporter of CVE-2012-0478; Anne van Kesteren of Opera Software as the original reporter of CVE-2012-0471; Matias Juntunen as the original reporter of CVE-2012-0473; Jordi Chancel and Eddy Bordi, and Chris McGowen as the original reporters of CVE-2012-0474; Masato Kinugawa as the original reporter of CVE-2012-0477; and Jeroen van der Gun as the original reporter of CVE-2012-0479.

Note: All issues except CVE-2012-0470, CVE-2012-0472, and CVE-2011-3062 cannot be exploited by a specially crafted HTML mail message as JavaScript is disabled by default for mail messages. It could be exploited another way in Thunderbird, for example, when viewing the full remote content of an RSS feed.
