Descriptions

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.

All versions of gnupg prior to 1.4.2.2 do not detect injection of unsigned data. Signature verification of non-detached signatures may give a positive result but when extracting the signed data, this data may be prepended or appended with extra data not covered by the signature. Thus it is possible for an attacker to take any signed message and inject extra arbitrary data.
