thunderbird security update

CentOS Errata and Security Advisory CESA-2007:0723

Mozilla Thunderbird is a standalone mail and newsgroup client.

Several flaws were found in the way Thunderbird processed certain malformed
JavaScript code. A malicious HTML email message containing JavaScript code
could cause Thunderbird to crash or potentially execute arbitrary code as
the user running Thunderbird. JavaScript support is disabled by default in
Thunderbird; these issues are not exploitable unless the user has enabled
JavaScript. (CVE-2007-3089, CVE-2007-3734, CVE-2007-3735, CVE-2007-3736,
CVE-2007-3737, CVE-2007-3738)

Users of Thunderbird are advised to upgrade to these erratum packages,
which contain backported patches that correct these issues.
