SynopsisThe remote Red Hat host is missing a security update.
DescriptionUpdated 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.
Mozilla Thunderbird is a standalone mail and newsgroup client.
The Mozilla Foundation has discontinued support for the Mozilla Thunderbird 1.0 branch. This update deprecates the Mozilla Thunderbird 1.0 branch in Red Hat Enterprise Linux 4 in favor of the supported Mozilla Thunderbird 1.5 branch.
This update also resolves a number of outstanding Thunderbird security issues :
(CVE-2006-2776, CVE-2006-2784, CVE-2006-2785, CVE-2006-2787, CVE-2006-3807, CVE-2006-3809)
Several denial of service flaws were found in the way Thunderbird processed certain mail messages. A malicious web page could crash the browser or possibly execute arbitrary code as the user running Thunderbird. (CVE-2006-2779, CVE-2006-2780, CVE-2006-3801, CVE-2006-3677, CVE-2006-3113, CVE-2006-3803, CVE-2006-3805, CVE-2006-3806, CVE-2006-3811)
Two flaws were found in the way Thunderbird displayed malformed inline vcard attachments. If a victim viewed an email message containing a carefully crafted vcard it was possible to execute arbitrary code as the user running Thunderbird. (CVE-2006-2781, CVE-2006-3804)
A cross site scripting flaw was found in the way Thunderbird processed Unicode Byte-order-Mark (BOM) markers in UTF-8 mail messages. A malicious web page could execute a script within the browser that a web input sanitizer could miss due to a malformed 'script' tag.
Two HTTP response smuggling flaws were found in the way Thunderbird processed certain invalid HTTP response headers. A malicious website could return specially crafted HTTP response headers which may bypass HTTP proxy restrictions. (CVE-2006-2786)
A double free flaw was found in the way the nsIX509::getRawDER method was called. If a victim visited a carefully crafted web page, it was possible to crash Thunderbird. (CVE-2006-2788)
Users of Thunderbird are advised to upgrade to this update, which contains Thunderbird version 18.104.22.168 that corrects these issues.
SolutionUpdate the affected thunderbird package.
