CVE-2017-17847 not yet assigned priority: Debian including 1 source packages (enigmail), 1 status rows across 1 suites (bullseye): resolved 1.
An issue was discovered in Enigmail before 1.9.9. Signature spoofing is possible because the UI does not properly distinguish between an attachment signature, and a signature that applies to the entire containing message, aka TBE-01-021. This is demonstrated by an e-mail message with an attachment that is a signed e-mail message in message/rfc822 format.
