Amazon Linux 2 Security Advisory: ALAS2-2025-2885
Advisory Released Date: 2025-06-12
Advisory Updated Date: 2025-06-12
Severity:
Medium
Issue Overview:
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. (CVE-2024-12243)
