NVD Description

Note: Versions mentioned in the description apply only to the upstream gnupg2 package and not the gnupg2 package as distributed by Ubuntu. See How to fix? for Ubuntu:21.10 relevant fixed versions and status.

GnuPG through 2.3.6, in unusual situations where an attacker possesses any secret-key information from a victim's keyring and other constraints (e.g., use of GPGME) are met, allows signature forgery via injection into the status line.
