Several vulnerabilities were found and fixed in Mozilla
Thunderbird.
Impact
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.
Workaround
There are no known workarounds for all the issues at this time.
Resolution
All Mozilla Thunderbird users should upgrade to the latest
version:
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.
