| CVE-2026-57062 | Low | 0.19 | 2.9 | 0.00 | Jun 23, 2026 | CMS (Cryptographic Message Syntax) parsing in gpgsm in GnuPG through 2.5.20 mishandles the CMS format for AES-GCM because aes-ICVlen is supposed to be 12 bytes but 4 bytes is accepted. NOTE: this is related to CVE-2026-34182. | ||
| CVE-2025-30258 | Low | 0.18 | 2.7 | 0.00 | Mar 19, 2025 | In GnuPG before 2.5.5, if a user chooses to import a certificate with certain crafted subkey data that lacks a valid backsig or that has incorrect usage flags, the user loses the ability to verify signatures made from certain other signing keys, aka a "verification DoS." | ||

| CVE-2007-1263 | 0.03 | — | 0.05 | Mar 6, 2007 | GnuPG 1.4.6 and earlier and GPGME before 1.1.4, when run from the command line, does not visually distinguish signed and unsigned portions of OpenPGP messages with multiple components, which might allow remote attackers to forge the contents of a message without detection. | |||
