Overview
openpgp is a JavaScript implementation of the OpenPGP protocol.
Affected versions of this package are vulnerable to Improper Authentication. OpenPGP signature subpackets contain information related to a signature (e.g. the creation timestamp). These subpackets may appear in a “hashed” and “unhashed” subpacket container. While the information in the hashed subpackets is signed, the unhashed subpackets are not cryptographically protected.
An attacker could arbitrarily modify the contents of e.g. a key certification signature or revocation signature. As a result, the attacker could e.g. convince a victim to use an obsolete key for encryption.
