CVE-2024-12133 [MEDIUM] CVE-2024-12133: libtasn1-6 - A flaw in libtasn1 causes inefficient handling of specific certificate data. Whe... A flaw in libtasn1 causes inefficient handling of specific certificate data. When processing a large number of elements in a certificate, libtasn1 takes much longer than expected, which can slow down or even crash the system. This flaw allows an attacker to send a specially crafted certificate, causing a denial of service attack. Scope: local bookworm: resolved
