This update fixes several security problems in Mozilla Thunderbird 1.5.0.12.

Following security problems were fixed :

  - MFSA 2007-18: Crashes with evidence of memory corruption

    The usual collection of stability fixes for crashes that     look suspicious but haven't been proven to be     exploitable.

    25 were in the browser engine, reported by Mozilla     developers and community members Bernd Mielke, Boris     Zbarsky, David Baron, Daniel Veditz, Jesse Ruderman,     Lukas Loehrer, Martijn Wargers, Mats Palmgren, Olli     Pettay, Paul Nickerson,and Vladimir Sukhoy     (CVE-2007-3734)

    7 were in the JavaScript engine reported by Asaf Romano,     Jesse Ruderman, Igor Bukanov (CVE-2007-3735)

  - MFSA 2007-19 / CVE-2007-3736: XSS using addEventListener     and setTimeout

    moz_bug_r_a4 reported that scripts could be injected     into another site's context by exploiting a timing issue     using addEventLstener or setTimeout.

  - MFSA 2007-20 / CVE-2007-3089: frame spoofing

    Ronen Zilberman and Michal Zalewski both reported that     it was possible to exploit a timing issue to inject     content into about:blank frames in a page.

  - MFSA 2007-21 / CVE-2007-3737: Privilege escalation using     an event handler attached to an element not in the     document

    Reported by moz_bug_r_a4.

  - MFSA 2007-22 / CVE-2007-3285: File type confusion due to     %00 in name

    Ronald van den Heetkamp reported that a filename URL     containing %00 (encoded null) can cause Firefox to     interpret the file extension differently than the     underlying Windows operating system potentially leading     to unsafe actions such as running a program.

  - MFSA 2007-23 / CVE-2007-3670: Remote code execution by     launching Firefox from Internet Explorer

    Greg MacManus of iDefense and Billy Rios of Verisign     independently reported that links containing a quote (')     character could be used in Internet Explorer to launch     registered URL Protocol handlers with extra command-line     parameters. Firefox and Thunderbird are among those     which can be launched, and both support a '-chrome'     option that could be used to run malware.

    This problem does not affect Linux.

  - MFSA 2007-24 / CVE-2007-3656: unauthorized access to     wyciwyg:// documents

    Michal Zalewski reported that it was possible to bypass     the same-origin checks and read from cached (wyciwyg)     documents

  - MFSA 2007-25 / CVE-2007-3738: XPCNativeWrapper pollution

    shutdown and moz_bug_r_a4 reported two separate ways to     modify an XPCNativeWrapper such that subsequent access     by the browser would result in executing user-supplied     code.

Updated Firefox packages that fix several security bugs are now available for Fedora 7.

Users of epiphany-extensions are advised to upgrade to this errata package, which has been rebuilt against the updated Firefox package.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Various flaws were discovered in the layout and JavaScript engines. By tricking a user into opening a malicious web page, an attacker could execute arbitrary code with the user's privileges. (CVE-2007-3734, CVE-2007-3735)

Flaws were discovered in the JavaScript methods addEventListener and setTimeout which could be used to inject script into another site in violation of the browser's same-origin policy. A malicious website could exploit this to modify the contents, or steal confidential data (such as passwords), of other web pages. (CVE-2007-3736)

Ronen Zilberman and Michal Zalewski discovered timing attacks in the JavaScript engine's use of about:blank frames. A malicious website could exploit this to modify the contents, or steal confidential data (such as passwords), of other web pages. (CVE-2007-3089)

A flaw was discovered in the JavaScript event handling code. By tricking a user into opening a malicious web page, an attacker could execute arbitrary code with the user's privileges. (CVE-2007-3737)

Ronald van den Heetkamp discovered that filename URLs including an encoded null byte could confuse the extension matching code. By tricking a user into opening a malicious web page, an attacker could execute arbitrary helper programs. (CVE-2007-3285)

Michal Zalewski discovered flaws in the same-origin handling of cached 'wyciwyg://' documents. A malicious website could exploit this to modify the contents, or steal confidential data (such as passwords), of other web pages. (CVE-2007-3656)

Various flaws were discovered in the XPCNativeWrapper method. By tricking a user into opening a malicious web page, an attacker could execute arbitrary code with the user's privileges. (CVE-2007-3738).

From Red Hat Security Advisory 2007:0723 :

Updated thunderbird packages that fix several security bugs are now available for Red Hat Enterprise Linux 4 and 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 way Thunderbird processed certain malformed JavaScript code. A malicious HTML email message containing JavaScript code could cause Thunderbird to crash or potentially execute arbitrary code as the user running Thunderbird. JavaScript support is disabled by default in Thunderbird; these issues are not exploitable unless the user has enabled JavaScript. (CVE-2007-3089, CVE-2007-3734, CVE-2007-3735, CVE-2007-3736, CVE-2007-3737, CVE-2007-3738)

Users of Thunderbird are advised to upgrade to these erratum packages, which contain backported patches that correct these issues.

The remote version of Mozilla Thunderbird suffers from various security issues, including at least one that could lead to execution of arbitrary code.

A number of security vulnerabilities have been discovered and corrected in the latest Mozilla Firefox program, version 2.0.0.6.

This update provides the latest Firefox to correct these issues. As well, it provides Firefox 2.0.0.6 for older products.

Versions of Mozilla Firefox prior to 2.0.0.5 are affected by various security issues, one of which may lead to execution of arbitrary code on the affected host subject to the user's privileges.

The installed version of Firefox is affected by various security issues, one of which may lead to execution of arbitrary code on the affected host subject to the user's privileges.
