Updated thunderbird packages that fix several security bugs are now available for Red Hat Enterprise Linux 4.

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

[Updated 06 March 2007] Updated text description to add CVE-2007-1282 and remove CVE-2007-0994, which was mistakenly listed as affecting Thunderbird. No changes have been made to these erratum packages.

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 mail message could execute JavaScript code in such a way that may result in Thunderbird crashing or executing 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-2007-0775, CVE-2007-0777, CVE-2007-1092)

A flaw was found in the way Thunderbird processed text/enhanced and text/richtext formatted mail message. A specially crafted mail message could execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2007-1282)

Several cross-site scripting (XSS) flaws were found in the way Thunderbird processed certain malformed HTML mail messages. A malicious HTML mail message could display misleading information which may result in a user unknowingly divulging sensitive information such as a password. (CVE-2006-6077, CVE-2007-0995, CVE-2007-0996)

A flaw was found in the way Thunderbird cached web content on the local disk. A malicious HTML mail message may be able to inject arbitrary HTML into a browsing session if the user reloads a targeted site. (CVE-2007-0778)

A flaw was found in the way Thunderbird displayed certain web content.
A malicious HTML mail message could generate content which could overlay user interface elements such as the hostname and security indicators, tricking a user into thinking they are visiting a different site. (CVE-2007-0779)

Two flaws were found in the way Thunderbird displayed blocked popup windows. If a user can be convinced to open a blocked popup, it is possible to read arbitrary local files, or conduct an XSS attack against the user. (CVE-2007-0780, CVE-2007-0800)

Two buffer overflow flaws were found in the Network Security Services (NSS) code for processing the SSLv2 protocol. Connecting to a malicious secure web server could cause the execution of arbitrary code as the user running Thunderbird. (CVE-2007-0008, CVE-2007-0009)

A flaw was found in the way Thunderbird handled the 'location.hostname' value during certain browser domain checks. This flaw could allow a malicious HTML mail message to set domain cookies for an arbitrary site, or possibly perform an XSS attack.
(CVE-2007-0981)

Users of Thunderbird are advised to apply this update, which contains Thunderbird version 1.5.0.10 that corrects these issues.

This update brings Mozilla Firefox to security update version 1.5.0.10.

  - As part of the Firefox 2.0.0.2 and 1.5.0.10 update     releases several bugs were fixed to improve the     stability of the browser. Some of these were crashes     that showed evidence of memory corruption and we presume     that with enough effort at least some of these could be     exploited to run arbitrary code. These fixes affected     the layout engine (CVE-2007-0775), SVG renderer     (CVE-2007-0776) and JavaScript engine. (CVE-2007-0777).
    (MFSA 2007-01)

  - Various enhancements were done to make XSS exploits     against websites less effective. These included fixes     for invalid trailing characters (CVE-2007-0995), child     frame character set inheritance (CVE-2007-0996),     password form injection (CVE-2006-6077), and the Adobe     Reader universal XSS problem. (MFSA 2007-02)

  - AAd reported a potential disk cache collision that could     be exploited by remote attackers to steal confidential     data or execute code. (MFSA 2007-03 / CVE-2007-0778)

  - David Eckel reported that browser UI elements--such as     the host name and security indicators--could be spoofed     by using a large, mostly transparent, custom cursor and     adjusting the CSS3 hotspot property so that the visible     part of the cursor floated outside the browser content     area. (MFSA 2007-04 / CVE-2007-0779)

  - Manually opening blocked popups could be exploited by     remote attackers to allow XSS attacks (CVE-2007-0780) or     to execute code in local files. (CVE-2007-0800). (MFSA     2007-05)

  - Two buffer overflows were found in the NSS handling of     Mozilla. (MFSA 2007-06)

  - SSL clients such as Firefox and Thunderbird can suffer a     buffer overflow if a malicious server presents a     certificate with a public key that is too small to     encrypt the entire 'Master Secret'. Exploiting this     overflow appears to be unreliable but possible if the     SSLv2 protocol is enabled. (CVE-2007-0008)

  - Servers that use NSS for the SSLv2 protocol can be     exploited by a client that presents a 'Client Master     Key' with invalid length values in any of several fields     that are used without adequate error checking. This can     lead to a buffer overflow that presumably could be     exploitable. (CVE-2007-0009)

  - Michal Zalewski demonstrated that setting     location.hostname to a value with embedded null     characters can confuse the browsers domain checks.
    Setting the value triggers a load, but the networking     software reads the hostname only up to the null     character while other checks for 'parent domain' start     at the right and so can have a completely different idea     of what the current host is. (MFSA 2007-06 /     CVE-2007-0981)

Versions of Mozilla Firefox 1.5.x prior ot 1.5.0.10, or 2.x prior to 2.0.0.2 are affected by various security issues, some of which may lead to execution of arbitrary code on the affected host subject to the user's privileges.

The remote host is running LedgerSMB or SQL-Ledger, a web-based double-entry accounting system.  The version of LedgerSMB or SQL-Ledger on the remote host contains a design flaw that can be leveraged by a remote attacker to bypass authentication and can gain administrative access of the application.

 The remote version of Mozilla Thunderbird suffers from various security issues, at least one of which may lead to execution of arbitrary code on the affected host subject to the user's privileges. 

The installed version of SeaMonkey contains various security issues, some 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, some of which may lead to execution of arbitrary code on the affected host subject to the user's privileges.

The remote version of Mozilla Thunderbird suffers from various security issues, at least one of which may lead to execution of arbitrary code on the affected host subject to the user's privileges.
