Mozilla Thunderbird is the next-generation mail client from the Mozilla project.
Several vulnerabilities were found and fixed in Mozilla Thunderbird.
A remote attacker could craft malicious emails that would leverage these issues to inject and execute arbitrary script code with elevated privileges, steal local files or other information from emails, and spoof content. Some of these vulnerabilities might even be exploited to execute arbitrary code with the rights of the user running Thunderbird.
There are no known workarounds for all the issues at this time.
All Mozilla Thunderbird users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/mozilla-thunderbird-1.0.8"
All Mozilla Thunderbird binary users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/mozilla-thunderbird-bin-1.0.8"
Note: There is no stable fixed version for the ALPHA architecture yet. Users of Mozilla Thunderbird on ALPHA should consider unmerging it until such a version is available.
