Several flaws were found in the processing of malformed HTML mail content. An HTML mail message containing malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code as the user running Thunderbird. (CVE-2008-5500, CVE-2008-5501, CVE-2008-5502, CVE-2008-5511, CVE-2008-5512, CVE-2008-5513)

Several flaws were found in the way malformed content was processed.
An HTML mail message containing specially crafted content could potentially trick a Thunderbird user into surrendering sensitive information. (CVE-2008-5503, CVE-2008-5506, CVE-2008-5507)

Note: JavaScript support is disabled by default in Thunderbird; the above issues are not exploitable unless JavaScript is enabled.

A flaw was found in the way malformed URLs were processed by Thunderbird. This flaw could prevent various URL sanitization mechanisms from properly parsing a malicious URL. (CVE-2008-5508)

All running instances of Thunderbird must be restarted for the update to take effect.

Several flaws were discovered in the browser engine. These problems could allow an attacker to crash the browser and possibly execute arbitrary code with user privileges. (CVE-2008-5500)

Boris Zbarsky discovered that the same-origin check in Firefox could be bypassed by utilizing XBL-bindings. An attacker could exploit this to read data from other domains. (CVE-2008-5503)

Marius Schilder discovered that Firefox did not properly handle redirects to an outside domain when an XMLHttpRequest was made to a same-origin resource. It's possible that sensitive information could be revealed in the XMLHttpRequest response. (CVE-2008-5506)

Chris Evans discovered that Firefox did not properly protect a user's data when accessing a same-domain JavaScript URL that is redirected to an unparsable JavaScript off-site resource. If a user were tricked into opening a malicious website, an attacker may be able to steal a limited amount of private data. (CVE-2008-5507)

Several flaws were discovered in the JavaScript engine. If a user were tricked into opening a malicious website, an attacker could exploit this to execute arbitrary JavaScript code within the context of another website or with chrome privileges. (CVE-2008-5511, CVE-2008-5512).

The Mozilla Firefox browser was updated to version 2.0.0.19, fixing various security issues and stability problems.

The following security issues were fixed :

MFSA 2008-69 / CVE-2008-5513: Mozilla security researcher moz_bug_r_a4 reported vulnerabilities in the session-restore feature by which content could be injected into an incorrect document storage location, including storage locations for other domains. An attacker could utilize these issues to violate the browser's same-origin policy and perform an XSS attack while SessionStore data is being restored.
moz_bug_r_a4 also reported that one variant could be used by an attacker to run arbitrary JavaScript with chrome privileges.

MFSA 2008-68 / CVE-2008-5512 / CVE-2008-5511: Mozilla security researcher moz_bug_r_a4 reported that an XBL binding, when attached to an unloaded document, can be used to violate the same-origin policy and execute arbitrary JavaScript within the context of a different website. moz_bug_r_a4 also reported two vulnerabilities by which page content can pollute XPCNativeWrappers and run arbitary JavaScript with chrome priviliges. Thunderbird shares the browser engine with Firefox and could be vulnerable if JavaScript were to be enabled in mail. This is not the default setting and we strongly discourage users from running JavaScript in mail. Workaround Disable JavaScript until a version containing these fixes can be installed.

MFSA 2008-67 / CVE-2008-5510: Kojima Hajime reported that unlike literal null characters which were handled correctly, the escaped form '\0' was ignored by the CSS parser and treated as if it was not present in the CSS input string. This issue could potentially be used to bypass script sanitization routines in web applications. The severity of this issue was determined to be low.

MFSA 2008-66 / CVE-2008-5508: Perl developer Chip Salzenberg reported that certain control characters, when placed at the beginning of a URL, would lead to incorrect parsing resulting in a malformed URL being output by the parser. IBM researchers Justin Schuh, Tom Cross, and Peter William also reported a related symptom as part of their research that resulted in MFSA 2008-37. There was no direct security impact from this issue and its effect was limited to the improper rendering of hyperlinks containing specific characters. The severity of this issue was determined to be low.

MFSA 2008-65 / CVE-2008-5507: Google security researcher Chris Evans reported that a website could access a limited amount of data from a different domain by loading a same-domain JavaScript URL which redirects to an off-domain target resource containing data which is not parsable as JavaScript. Upon attempting to load the data as JavaScript a syntax error is generated that can reveal some of the file context via the window.onerror DOM API. This issue could be used by a malicious website to steal private data from users who are authenticated on the redirected website. How much data could be at risk would depend on the format of the data and how the JavaScript parser attempts to interpret it. For most files the amount of data that can be recovered would be limited to the first word or two. Some data files might allow deeper probing with repeated loads. Thunderbird shares the browser engine with Firefox and could be vulnerable if JavaScript were to be enabled in mail. This is not the default setting and we strongly discourage users from running JavaScript in mail.
Workaround Disable JavaScript until a version containing these fixes can be installed.

MFSA 2008-64 / CVE-2008-5506: Marius Schilder of Google Security reported that when a XMLHttpRequest is made to a same-origin resource which 302 redirects to a resource in a different domain, the response from the cross-domain resource is readable by the site issuing the XHR. Cookies marked HttpOnly were not readable, but other potentially sensitive data could be revealed in the XHR response including URL parameters and content in the response body. Thunderbird shares the browser engine with Firefox and could be vulnerable if JavaScript were to be enabled in mail. This is not the default setting and we strongly discourage users from running JavaScript in mail. Workaround Disable JavaScript until a version containing these fixes can be installed.

MFSA 2008-62 / CVE-2008-5504: Mozilla security researcher moz_bug_r_a4 reported an additional variation on the feed preview vulnerabilities fixed in Firefox 2.0.0.17. moz_bug_r_a4 demonstrated that it was still possible to use the feed preview as a vector for JavaScript privilege escalation. An attacker could use this issue to run arbitrary JavaScript with chrome privileges. Firefox 3 is not affected by this issue. Workaround Disable JavaScript until a version containing these fixes can be installed.

MFSA 2008-61 / CVE-2008-5503: Mozilla developer Boris Zbarsky reported that XBL bindings could be used to read data from other domains, a violation of the same-origin policy. The severity of this issue was determined to be moderate due to several mitigating factors: The target document requires a <bindingsi> element in the XBL namespace in order to be read. The reader of the data needs to know the id attribute of the binding being read in advance. It is unlikely that web services will expose private data in the manner described above.
Firefox 3 is not affected by this issue. Thunderbird shares the browser engine with Firefox and could be vulnerable if JavaScript were to be enabled in mail. This is not the default setting and we strongly discourage users from running JavaScript in mail. Workaround Products built from the Mozilla 1.9.0 branch and later, Firefox 3 for example, are not affected by this issue. Upgrading to one of these products is a reliable workaround for this particular issue and it is also Mozilla's recommendation that the most current version of any Mozilla product be used. Alternatively, you can disable JavaScript until a version containing these fixes can be installed.

MFSA 2008-60 / CVE-2008-5500: Mozilla developers identified and fixed several stability bugs in the browser engine used in Firefox and other Mozilla-based products. Some of these crashes 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. Thunderbird shares the browser engine with Firefox and could be vulnerable if JavaScript were to be enabled in mail. This is not the default setting and we strongly discourage users from running JavaScript in mail. Without further investigation we cannot rule out the possibility that for some of these an attacker might be able to prepare memory for exploitation through some means other than JavaScript such as large images. Workaround Disable JavaScript until a version containing these fixes can be installed.

Several remote vulnerabilities have been discovered in the Iceweasel web browser, an unbranded version of the Firefox browser. The Common Vulnerabilities and Exposures project identifies the following problems :

    (MFSA 2008-66)

  - CVE-2008-5510     Kojima Hajime and Jun Muto discovered that escaped null     characters were ignored by the CSS parser and could lead     to the bypass of protection mechanisms (MFSA 2008-67)

  - CVE-2008-5511     It was discovered that it is possible to perform     cross-site scripting attacks via an XBL binding to an     'unloaded document.' (MFSA 2008-68)

  - CVE-2008-5512     It was discovered that it is possible to run arbitrary     JavaScript with chrome privileges via unknown vectors.
    (MFSA 2008-68)

  - CVE-2008-5513     moz_bug_r_a4 discovered that the session-restore feature     does not properly sanitise input leading to arbitrary     injections. This issue could be used to perform an XSS     attack or run arbitrary JavaScript with chrome     privileges. (MFSA 2008-69)

Security vulnerabilities have been discovered and corrected in the latest Mozilla Firefox 2.x, version 2.0.0.19 (CVE-2008-5500, CVE-2008-5503, CVE-2008-5504, CVE-2008-5506, CVE-2008-5507, CVE-2008-5508, CVE-2008-5510, CVE-2008-5511, CVE-2008-5512, CVE-2008-5513).

MFSA 2008-63 / CVE-2008-5505: Security researcher Hish reported that the persist attribute in XUL elements can be used to store cookie-like information on a user's computer which could later be read by a website. This creates a privacy issue for users who have a non-standard cookie preference and wish to prevent sites from setting cookies on their machine. Even with cookies turned off, this issue could be used by a website to write persistent data in a user's browser and track the user across browsing sessions. Additionally, this issue could allow a website to bypass the limits normally placed on cookie size and number.
