CWEhttps://cwe.mitre.org/data/definitions/706.html

mainproc.c in GnuPG before 2.2.8 mishandles the original filename during decryption and verification actions, which allows remote attackers to spoof the output that GnuPG sends on file descriptor 2 to other programs that use the –status-fd 2 option. For example, the OpenPGP data might represent an original filename that contains line feed characters in conjunction with GOODSIG or VALIDSIG status codes.

Weakness

The product uses a name or reference to access a resource, but the name/reference resolves to a resource that is outside of the intended control sphere.
