CVE-2019-11755

Priority
Description
A crafted S/MIME message consisting of an inner encryption layer and an
outer SignedData layer was shown as having a valid digital signature,
although the signer might have had no access to the contents of the
encrypted message, and might have stripped a different signature from the
encrypted message. Previous versions had only suppressed showing a digital
signature for messages with an outer multipart/signed layer. This
vulnerability affects Thunderbird < 68.1.1.
