Package : libtasn1-6 Version : 4.16.0-2+deb11u2 CVE ID : CVE-2024-12133 Debian Bug : 1095406

Bing Shi discovered that libtasn1-6, a runtime library to manage ASN.1 structures, had inefficient handling of certificate data with a large number of names or name constraints, potentially leading to Denial of Service upon specially crafted certificates.

For Debian 11 bullseye, this problem has been fixed in version 4.16.0-2+deb11u2.

We recommend that you upgrade your libtasn1-6 packages.
