Mozilla Thunderbird is a standalone mail and newsgroup client.

This update upgrades Thunderbird to version 38.8.0.

Security Fix(es):

• Two flaws were found in the processing of malformed web content. A web page
  containing malicious content could cause Thunderbird to crash or, potentially,
  execute arbitrary code with the privileges of the user running Thunderbird.

Red Hat would like to thank the Mozilla project for reporting these issues.
