Name of the Vulnerable Software and Affected Versions
openssl encrypt versions prior to 1.4.9
Description
The software fails to prevent namespace collisions between own identities and contacts within the IdentityStore. This allows attackers to create shadowed contact entries that remain invisible as long as the corresponding own identity exists. Once the own identity is deleted, the shadowed contact becomes visible and resolves to the attacker's keys, which enables silent key substitution for encrypted files.
Recommendations
Update to version 1.4.9 or later.
