thunderbird security update

CentOS Errata and Security Advisory CESA-2008:0616

Mozilla Thunderbird is a standalone mail and newsgroup client.

Multiple flaws were found in the processing of malformed JavaScript
content. An HTML mail containing such malicious content could cause
Thunderbird to crash or, potentially, execute arbitrary code as the user
running Thunderbird. (CVE-2008-2801, CVE-2008-2802, CVE-2008-2803)

Several flaws were found in the processing of malformed HTML content. An
HTML mail containing malicious content could cause Thunderbird to crash or,
potentially, execute arbitrary code as the user running Thunderbird.
(CVE-2008-2785, CVE-2008-2798, CVE-2008-2799, CVE-2008-2811)

Several flaws were found in the way malformed HTML content was displayed.
An HTML mail containing specially-crafted content could, potentially, trick
a Thunderbird user into surrendering sensitive information. (CVE-2008-2800)

Two local file disclosure flaws were found in Thunderbird. An HTML mail
containing malicious content could cause Thunderbird to reveal the contents
of a local file to a remote attacker. (CVE-2008-2805, CVE-2008-2810)

A flaw was found in the way a malformed .properties file was processed by
Thunderbird. A malicious extension could read uninitialized memory,
possibly leaking sensitive data to the extension. (CVE-2008-2807)

A flaw was found in the way Thunderbird escaped a listing of local file
names. If a user could be tricked into listing a local directory containing
malicious file names, arbitrary JavaScript could be run with the
permissions of the user running Thunderbird. (CVE-2008-2808)

A flaw was found in the way Thunderbird displayed information about
self-signed certificates. It was possible for a self-signed certificate to
contain multiple alternate name entries, which were not all displayed to
the user, allowing them to mistakenly extend trust to an unknown site.
(CVE-2008-2809)

Note: JavaScript support is disabled by default in Thunderbird. The above
issues are not exploitable unless JavaScript is enabled.

All Thunderbird users should upgrade to these updated packages, which
contain backported patches to resolve these issues.
