Summary
libtasn1 security update
Details

Libtasn1 is the ASN.1 library used by GnuTLS, p11-kit and some other packages. The goal of this implementation is to be highly portable, and only require an ANSI C99 platform.This library provides Abstract Syntax Notation One (ASN.1, as specified by the X.680 ITU-T recommendation) parsing and structures management, and Distinguished Encoding Rules (DER, as per X.690) encoding and decoding functions.

Security Fix(es):

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.(CVE-2024-12133)
