Debian DSA-4355-1 : openssl1.0 - security update

medium Nessus Plugin ID 119792
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

Several local side channel attacks and a denial of service via large Diffie-Hellman parameters were discovered in OpenSSL, a Secure Sockets Layer toolkit.

Solution

Upgrade the openssl1.0 packages.

For the stable distribution (stretch), these problems have been fixed in version 1.0.2q-1~deb9u1. Going forward, openssl1.0 security updates for stretch will be based on the 1.0.2x upstream releases.
