Debian DSA-4348-1 : openssl - security update

medium Nessus Plugin ID 119313

Language:

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 openssl packages.

For the stable distribution (stretch), these problems have been fixed in version 1.1.0j-1~deb9u1. Going forward, openssl security updates for stretch will be based on the 1.1.0x upstream releases.
