Vulnerability from osv_openeuler – Published: 2025-04-03 11:08 – Updated: 2026-08-06 11:08 – Source website

Summary

gnupg2 security update

Details

GnuPG is a complete and free implementation of the OpenPGP standard as defined by RFC4880 (also known as PGP). GnuPG enables encryption and signing of data and communication, and features a versatile key management system as well as access modules for public key directories.

Security Fix(es):

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-2025-30258)

Severity

2.7 (Low)
