NVD Description

Note: Versions mentioned in the description apply only to the upstream gnutls package and not the gnutls package as distributed by Alpine. See How to fix? for Alpine:3.21 relevant fixed versions and status.

A flaw was found in GnuTLS, which relies on libtasn1 for ASN.1 data processing. Due to an inefficient algorithm in libtasn1, decoding certain DER-encoded certificate data can take excessive time, leading to increased resource consumption. This flaw allows a remote attacker to send a specially crafted certificate, causing GnuTLS to become unresponsive or slow, resulting in a denial-of-service condition.
