Synopsis

The remote Debian host is missing a security update.

Description

A vulnerability has been discovered in Libtasn1, a library to manage ASN.1 structures, allowing a remote attacker to cause a denial of service against an application using the Libtasn1 library.

For Debian 8 'Jessie', this problem has been fixed in version 4.2-3+deb8u4.

We recommend that you upgrade your libtasn1-6 packages.
