Fedora Core 6: FEDORA-2007-550 Critical: Thunderbird JavaScript Flaws

Mozilla Thunderbird is a standalone mail and newsgroup client.

Updated thunderbird packages that fix several security bugs

are now available for Fedora Core.

This update has been rated as having critical security

impact by the Fedora 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 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.
