Name of the Vulnerable Software and Affected Versions Enigmail versions prior to 1.9.9

Description An issue in Enigmail allows signature spoofing because the UI does not properly distinguish between an attachment signature and a signature that applies to the entire containing message. This can be demonstrated by an e-mail message with an attachment that is a signed e-mail message in message/rfc822 format.

Recommendations For versions prior to 1.9.9, update to version 1.9.9 or later to resolve the issue.
