The Mozilla Foundation reports of multiple security issues in Firefox, SeaMonkey, and Thunderbird. Several of these issues can probably be used to run arbitrary code with the privilege of the user running the program.

- Web forgery overwrite with div overlay

- URL token stealing via stylesheet redirect

- Mishandling of locally-saved plain text files

- File action dialog tampering

- Possible information disclosure in BMP decoder

- Web browsing history and forward navigation stealing

- Directory traversal via chrome: URI

- Stored password corruption

- Privilege escalation, XSS, Remote Code Execution

- Multiple file input focus stealing vulnerabilities

- Crashes with evidence of memory corruption (rv:1.8.1.12)

This update of the Mozilla XULRunner engine catches up on all previous security problems found in the XULRunner engine.

Following security problems were fixed :

  - MFSA 2008-11/CVE-2008-0594 Web forgery overwrite with     div overlay

Updated thunderbird 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.

[Updated 27th February 2008] The erratum text has been updated to include the details of additional issues that were fixed by these erratum packages, but which were not public at the time of release. No changes have been made to the packages.

Mozilla Thunderbird is a standalone mail and newsgroup client.

A heap-based buffer overflow flaw was found in the way Thunderbird processed messages with external-body Multipurpose Internet Message Extensions (MIME) types. A HTML mail message containing malicious content could cause Thunderbird to execute arbitrary code as the user running Thunderbird. (CVE-2008-0304)

Several flaws were found in the way Thunderbird processed certain malformed HTML mail content. A HTML mail message containing malicious content could cause Thunderbird to crash, or potentially execute arbitrary code as the user running Thunderbird. (CVE-2008-0412, CVE-2008-0413, CVE-2008-0415, CVE-2008-0419)

Several flaws were found in the way Thunderbird displayed malformed HTML mail content. A HTML mail message containing specially crafted content could trick a user into surrendering sensitive information.
(CVE-2008-0420, CVE-2008-0591, CVE-2008-0593)

A flaw was found in the way Thunderbird handles certain chrome URLs.
If a user has certain extensions installed, it could allow a malicious HTML mail message to steal sensitive session data. Note: this flaw does not affect a default installation of Thunderbird. (CVE-2008-0418)

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 Thunderbird saves certain text files. If a remote site offers a file of type 'plain/text', rather than 'text/plain', Thunderbird will not show future 'text/plain' content to the user, forcing them to save those files locally to view the content. (CVE-2008-0592)

Users of thunderbird are advised to upgrade to these updated packages, which contain backported patches to resolve these issues.

The remote host is affected by the vulnerability described in GLSA-200805-18 (Mozilla products: Multiple vulnerabilities)

    The following vulnerabilities were reported in all mentioned Mozilla     products:

    Gerry Eisenhaur discovered a directory traversal vulnerability when     using 'flat' addons (CVE-2008-0418).
    Alexey Proskuryakov, Yosuke Hasegawa and Simon Montagu reported     multiple character handling flaws related to the backspace character,     the '0x80' character, involving zero-length non-ASCII sequences in     multiple character sets, that could facilitate Cross-Site Scripting     attacks (CVE-2008-0416).
    The following vulnerability was reported in Thunderbird and SeaMonkey:
    regenrecht (via iDefense) reported a heap-based buffer overflow when     rendering an email message with an external MIME body (CVE-2008-0304).
    The following vulnerabilities were reported in Firefox, SeaMonkey and     XULRunner:
    The fix for CVE-2008-1237 in Firefox 2.0.0.13     and SeaMonkey 1.1.9 introduced a new crash vulnerability     (CVE-2008-1380).
    hong and Gregory Fleischer each reported a     variant on earlier reported bugs regarding focus shifting in file input     controls (CVE-2008-0414).
    Gynvael Coldwind (Vexillium) discovered that BMP images could be used     to reveal uninitialized memory, and that this data could be extracted     using a 'canvas' feature (CVE-2008-0420).
    Chris Thomas reported that background tabs could create a borderless     XUL pop-up in front of pages in other tabs (CVE-2008-1241).
    oo.rio.oo discovered that a plain text file with a     'Content-Disposition: attachment' prevents Firefox from rendering     future plain text files within the browser (CVE-2008-0592).
    Martin Straka reported that the '.href' property of stylesheet DOM     nodes is modified to the final URI of a 302 redirect, bypassing the     same origin policy (CVE-2008-0593).
    Gregory Fleischer discovered that under certain circumstances, leading     characters from the hostname part of the 'Referer:' HTTP header are     removed (CVE-2008-1238).
    Peter Brodersen and Alexander Klink reported that the browser     automatically selected and sent a client certificate when SSL Client     Authentication is requested by a server (CVE-2007-4879).
    Gregory Fleischer reported that web content fetched via the 'jar:'     protocol was not subject to network access restrictions     (CVE-2008-1240).
    The following vulnerabilities were reported in Firefox:
    Justin Dolske discovered a CRLF injection vulnerability when storing     passwords (CVE-2008-0417).
    Michal Zalewski discovered that Firefox does not properly manage a     delay timer used in confirmation dialogs (CVE-2008-0591).
    Emil Ljungdahl and Lars-Olof Moilanen discovered that a web forgery     warning dialog is not displayed if the entire contents of a web page     are in a DIV tag that uses absolute positioning (CVE-2008-0594).
  Impact :

    A remote attacker could entice a user to view a specially crafted web     page or email that will trigger one of the vulnerabilities, possibly     leading to the execution of arbitrary code or a Denial of Service. It     is also possible for an attacker to trick a user to upload arbitrary     files when submitting a form, to corrupt saved passwords for other     sites, to steal login credentials, or to conduct Cross-Site Scripting     and Cross-Site Request Forgery attacks.
  Workaround :

    There is no known workaround at this time.

A number of security vulnerabilities have been discovered and corrected in the latest Mozilla Thunderbird program, version 2.0.0.12.

This update provides the latest Thunderbird to correct these issues.

The installed version of Firefox is affected by various security issues :

 - Several stability bugs leading to crashes that, in some cases, show traces of memory corruption
 - Several file input focus stealing vulnerabilities that could result in uploading of arbitrary files provided their full path and file names are known.
 - Several issues that allow scripts from page content to escape from their sandboxed context and/or run with chrome privileges, resulting in privilege escalation, XSS and/or remote code execution.
 - An issue that could allow a malicious site to inject newlines into the application's password store when a user saves his password, resulting in corruption of saved passwords for other sites.
 - A directory traversal vulnerability via the 'chrome:' URI.
 - A vulnerability involving 'designMode' frames that may result in web browsing history and forward navigation stealing.
 - A file action dialog tampering vulnerability involving timer-enabled security dialogs.
