RHSA-2007:0401 - Critical: thunderbird security update

Synopsis

Critical: thunderbird security update

Type/Severity

Security Advisory Critical

Topic

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 critical security impact by the Red Hat Security Response Team.

Description

Mozilla Thunderbird is a standalone mail and newsgroup client.

Several flaws were found in the way Thunderbird processed certain malformed JavaScript code. A web page containing malicious JavaScript code could cause Thunderbird to crash or potentially execute arbitrary code as the user running Thunderbird. (CVE-2007-2867, CVE-2007-2868)

Several denial of service flaws were found in the way Thunderbird handled certain form and cookie data. A malicious web site that is able to set arbitrary form and cookie data could prevent Thunderbird from functioning properly. (CVE-2007-1362, CVE-2007-2869)

A flaw was found in the way Thunderbird processed certain APOP authentication requests. By sending certain responses when Thunderbird attempted to authenticate against an APOP server, a remote attacker could potentially acquire certain portions of a user's authentication credentials. (CVE-2007-1558)

A flaw was found in the way Thunderbird displayed certain web content. A malicious web page could generate content which could overlay user interface elements such as the hostname and security indicators, tricking users into thinking they are visiting a different site. (CVE-2007-2871)

Users of Thunderbird are advised to apply this update, which contains Thunderbird version 1.5.0.12 that corrects these issues.
