GHSA-CQJ4-FP95-JQXQ
Vulnerability from github – Published: 2025-02-10 18:30 – Updated: 2026-05-12 12:32
VLAI
Details
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.
Severity
5.3 (Medium)
