CVE-2024-12133

Name of the Vulnerable Software and Affected Versions libtasn1 (affected versions not specified)

Description 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. The issue is related to the handling of numerous SEQUENCE OF or SET OF elements in DER data, which results in quadratic time complexity.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
