libtasn1: Inefficient DER Decoding in libtasn1 Leading to Potential Remote DoS

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,...

Moderate: libtasn1 security update

A library that 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 Fixes: libtasn1: Inefficient DER Decoding in libtasn1 Leading ...

Medium: gnutls

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...
