CVE-2006-0049: GNU Privacy Guard

Medium severity, CVSS 5.0. EPSS: 2.4% chance of exploitation in the next 30 days.

gpg in GnuPG before 1.4.2.2 does not properly verify non-detached signatures, which allows attackers to inject unsigned data via a data packet that is not associated with a control packet, which causes the check for concatenated signatures to report that the signature is valid, a different vulnerability than CVE-2006-0455.
