Debian DSA-3256-1 : libtasn1-6 - security update

medium Nessus Plugin ID 83308
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security-related update.

Description

Hanno Boeck discovered a heap-based buffer overflow flaw in the way Libtasn1, a library to manage ASN.1 structures, decoded certain DER-encoded input. A specially crafted DER-encoded input could cause an application using the Libtasn1 library to crash, or potentially to execute arbitrary code.

Solution

Upgrade the libtasn1-6 packages.

For the stable distribution (jessie), this problem has been fixed in version 4.2-3+deb8u1.
