RHEL 4 : thunderbird (RHSA-2005:791)

high Nessus Plugin ID 19995


The remote Red Hat host is missing a security update.


An updated thunderbird package that fixes various bugs is now available for Red Hat Enterprise Linux 4.

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

Mozilla Thunderbird is a standalone mail and newsgroup client.

A bug was found in the way Thunderbird processes certain international domain names. An attacker could create a specially crafted HTML mail, which when viewed by the victim would cause Thunderbird to crash or possibly execute arbitrary code. Thunderbird as shipped with Red Hat Enterprise Linux 4 must have international domain names enabled by the user in order to be vulnerable to this issue. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-2871 to this issue.

A bug was found in the way Thunderbird processes certain Unicode sequences. It may be possible to execute arbitrary code as the user running Thunderbird if the user views a specially crafted HTML mail containing Unicode sequences. (CVE-2005-2702)

A bug was found in the way Thunderbird makes XMLHttp requests. It is possible that a malicious HTML mail could leverage this flaw to exploit other proxy or server flaws from the victim's machine. It is also possible that this flaw could be leveraged to send XMLHttp requests to hosts other than the originator; the default behavior of Thunderbird is to disallow such actions. (CVE-2005-2703)

A bug was found in the way Thunderbird implemented its XBL interface.
It may be possible for a malicious HTML mail to create an XBL binding in such a way that would allow arbitrary JavaScript execution with chrome permissions. Please note that in Thunderbird 1.0.6 this issue is not directly exploitable and will need to leverage other unknown exploits. (CVE-2005-2704)

An integer overflow bug was found in Thunderbird's JavaScript engine.
Under favorable conditions, it may be possible for a malicious mail message to execute arbitrary code as the user running Thunderbird.
Please note that JavaScript support is disabled by default in Thunderbird. (CVE-2005-2705)

A bug was found in the way Thunderbird displays about: pages. It is possible for a malicious HTML mail to open an about: page, such as about:mozilla, in such a way that it becomes possible to execute JavaScript with chrome privileges. (CVE-2005-2706)

A bug was found in the way Thunderbird opens new windows. It is possible for a malicious HTML mail to construct a new window without any user interface components, such as the address bar and the status bar. This window could then be used to mislead the user for malicious purposes. (CVE-2005-2707)

A bug was found in the way Thunderbird processes URLs passed to it on the command line. If a user passes a malformed URL to Thunderbird, such as clicking on a link in an instant messaging program, it is possible to execute arbitrary commands as the user running Thunderbird. (CVE-2005-2968)

Users of Thunderbird are advised to upgrade to this updated package, which contains Thunderbird version 1.0.7 and is not vulnerable to these issues.
