Several remote vulnerabilities have been discovered in Xulrunner, a runtime environment for XUL applications, such as the Iceweasel web browser. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2009-1392     Several issues in the browser engine have been     discovered, which can result in the execution of     arbitrary code. (MFSA 2009-24)

  - CVE-2009-1832     It is possible to execute arbitrary code via vectors     involving 'double frame construction.' (MFSA 2009-24)

  - CVE-2009-1833     Jesse Ruderman and Adam Hauner discovered a problem in     the JavaScript engine, which could lead to the execution     of arbitrary code. (MFSA 2009-24)

  - CVE-2009-1834     Pavel Cvrcek discovered a potential issue leading to a     spoofing attack on the location bar related to certain     invalid unicode characters. (MFSA 2009-25)

  - CVE-2009-1835     Gregory Fleischer discovered that it is possible to read     arbitrary cookies via a crafted HTML document. (MFSA     2009-26)

  - CVE-2009-1836     Shuo Chen, Ziqing Mao, Yi-Min Wang and Ming Zhang     reported a potential man-in-the-middle attack, when     using a proxy due to insufficient checks on a certain     proxy response. (MFSA 2009-27)

  - CVE-2009-1837     Jakob Balle and Carsten Eiram reported a race condition     in the NPObjWrapper_NewResolve function that can be used     to execute arbitrary code. (MFSA 2009-28)

  - CVE-2009-1838     moz_bug_r_a4 discovered that it is possible to execute     arbitrary JavaScript with chrome privileges due to an     error in the garbage-collection implementation. (MFSA     2009-29)

  - CVE-2009-1839     Adam Barth and Collin Jackson reported a potential     privilege escalation when loading a file::resource via     the location bar. (MFSA 2009-30)

  - CVE-2009-1840     Wladimir Palant discovered that it is possible to bypass     access restrictions due to a lack of content policy     check, when loading a script file into a XUL document.
    (MFSA 2009-31)

  - CVE-2009-1841     moz_bug_r_a4 reported that it is possible for scripts     from page content to run with elevated privileges and     thus potentially executing arbitrary code with the     object's chrome privileges. (MFSA 2009-32)

The installed version of Thunderbird is earlier than 2.0.0.22.  Such versions are potentially affected by the following security issues :

  - Multiple memory corruption vulnerabilities could     potentially be exploited to execute arbitrary code     provided JavaScript is enabled in mail.     (MFSA 2009-14)

  - When an Adobe Flash file is loaded via the     'view-source:' scheme, the Flash plugin misinterprets     the origin of the content as localhost. An attacker can     leverage this to launch cross-site request forgery     attacks. It is also possible to exploit this to place     cookie-like objects on victim's computers.
    (MFSA 2009-17)

  - Multiple memory corruption vulnerabilities could     potentially be exploited to execute arbitrary code.
    (MFSA 2009-24)

  - It may be possible to tamper with SSL data via non-200     responses to proxy CONNECT requests. (MFSA 2009-27)

  - If the owner document of an element becomes null after     garbage collection, then it may be possible to execute     the event listeners within the wrong JavaScript context.
    An attacker can potentially exploit this vulnerability     to execute arbitrary JavaScript with chrome privileges,     provided JavaScript is enabled in mail. (MFSA 2009-29)

  - It may be possible for scripts from page content to     run with elevated privileges. Thunderbird installs are     not affected by default, however if an add-on is     installed that implements functionality similar to     sidebar or BrowserFeedWriter, and also enables     JavaScript then the install could be vulnerable.
    (MFSA 2009-32)

  - It may be possible to crash Thunderbird while viewing a     'multipart/alternative' mail message with a     'text/enhanced' part. (MFSA 2009-33)

New seamonkey packages are available for Slackware 11.0, 12.0, 12.1, 12.2, and -current to fix security issues.

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

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

Mozilla Thunderbird is a standalone mail and newsgroup client.

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-2009-1392, CVE-2009-1303, CVE-2009-1305, CVE-2009-1833, CVE-2009-1838)

Several flaws were found in the way malformed HTML mail content was processed. An HTML mail message containing malicious content could execute arbitrary JavaScript in the context of the mail message, possibly presenting misleading data to the user, or stealing sensitive information such as login credentials. (CVE-2009-1306, CVE-2009-1307, CVE-2009-1308, CVE-2009-1309)

A flaw was found in the way Thunderbird handled error responses returned from proxy servers. If an attacker is able to conduct a man-in-the-middle attack against a Thunderbird instance that is using a proxy server, they may be able to steal sensitive information from the site Thunderbird is displaying. (CVE-2009-1836)

Note: JavaScript support is disabled by default in Thunderbird. None of the above issues are exploitable unless JavaScript is enabled.

All Thunderbird users should upgrade to this updated package, which resolves these issues. All running instances of Thunderbird must be restarted for the update to take effect.

From Red Hat Security Advisory 2009:1095 :

Updated firefox packages that fix several security issues are now available for Red Hat Enterprise Linux 4 and 5.

This update has been rated as having critical security impact by the Red Hat Security Response Team.

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 as the user running Firefox.
(CVE-2009-1392, CVE-2009-1832, CVE-2009-1833, CVE-2009-1837, CVE-2009-1838, CVE-2009-1841)

Multiple flaws were found in the processing of malformed, local file content. If a user loaded malicious, local content via the file:// URL, it was possible for that content to access other local data.
(CVE-2009-1835, CVE-2009-1839)

A script, privilege elevation flaw was found in the way Firefox loaded XML User Interface Language (XUL) scripts. Firefox and certain add-ons could load malicious content when certain policy checks did not happen. (CVE-2009-1840)

A flaw was found in the way Firefox displayed certain Unicode characters in International Domain Names (IDN). If an IDN contained invalid characters, they may have been displayed as spaces, making it appear to the user that they were visiting a trusted site.
(CVE-2009-1834)

A flaw was found in the way Firefox handled error responses returned from proxy servers. If an attacker is able to conduct a man-in-the-middle attack against a Firefox instance that is using a proxy server, they may be able to steal sensitive information from the site the user is visiting. (CVE-2009-1836)

For technical details regarding these flaws, refer to the Mozilla security advisories for Firefox 3.0.11. You can find a link to the Mozilla advisories in the References section of this errata.

All Firefox users should upgrade to these updated packages, which contain Firefox version 3.0.11, which corrects these issues. After installing the update, Firefox must be restarted for the changes to take effect.

The version of Google Chrome installed on the remote host is earlier than 1.0.154.53. Such versions are reportedly affected by a multiple vulnerabilities : 

  - The browser uses the HTTP Host header to determine the context of a 4xx/5xx CONNECT response from a proxy server. This could allow a man-in-the-middle attacker to execute arbitrary script code in the context of a legitimate server. (CVE-2009-2060)

  - The browser displays a cached certificate for 4xx/5xx CONNECT response pages from a proxy server. A man-in-the-middle attacker could exploit this by displaying a spoofed web page with the valid certificate of a legitimate website.

Versions of Firefox prior to 3.0.11 are affected by the following security issues : 

 - Multiple memory corruption vulnerabilities could potentially be exploited to execute arbitrary code. (MFSA 2009-24)
 - Certain invalid Unicode characters, when used as a part of IDN, can be displayed as a whitespace in the location bar. An attacker can exploit this vulnerability to spoof the location bar. (MFSA 2009-25)
 - It may be possible for local resources loaded via 'file: ' protocol to access any domain's cookies saved on a user's system. (MFSA 2009-26)
 - It may be possible to tamper with SSL date via non-200 responses to proxy CONNECT requests. (MFSA 2009-27)
 - A race condition exists in 'NPObjWrapper_NewResolve' when accessing the properties of a NPObject, a wrapped JSObject. (MFSA 2009-28)
 - If the owner document of an element becomes a null after garbage collection, then it may be possible to execute the event listeners within the wrong JavaScript context. An attacker can potentially exploit this vulnerability to execute arbitrary JavaScript with chrome privileges. (MFSA 2009-29)
 - When the 'file: ' resource is loaded from the location bar, the resource inherits principal of the previously loaded document. This could potentially allow unauthorized access to local files. (MFSA-2009-30)
 - While loading external scripts into XUL documents content-loading policies are not checked. (MFSA 2009-31)
 - It may also be possible for scripts from page content to run with elevated privileges. (MFSA 2009-32)
