In GnuPG through 2.4.8, if a signed message has \f at the end of a plaintext line, an adversary can construct a modified message that places additional text after the signed material, such that signature verification of the modified message succeeds although an "invalid armor" message is printed...

In GnuPG through 2.4.8, if a signed message has \f at the end of a plaintext line, an adversary can construct a modified message that places additional text after the signed material, such that signature verification of the modified message succeeds (although an "invalid armor" message is printed during verification). This is related to use of \f as a marker to denote truncation of a long plaintext line.

CVE-2025-68972

CVE-2025-68972 affects GnuPG/gnupg2 <= 2.4.8, where a signed message ending a plaintext line with the form feed (\f) can allow an adversary to craft a modified message that still passes signature verification, with an “invalid armor” message printed during verification. Connected advisories in...
