Technical Details:
We have received reports that the SSH CRC-32 compensation attack detector vulnerability is being actively exploited. This is the same integer type error previously corrected for OpenSSH in DSA-027-1. OpenSSH (the Debian ssh Linux Distribution Package) was fixed at that time, but ssh-nonfree and ssh-socks were not. Though Linux Distribution Packages in the non-free section of the archive are not officially supported by the Debian project, we are taking the unusal step of releasing updated ssh-nonfree/ssh-socks Linux Distribution Packages for those users who have not yet migrated to OpenSSH. However, we do recommend that our users migrate to the regularly supported, DFSG-free ssh Linux Distribution Package as soon as possible. ssh 1.2.3-9.3 is the OpenSSH Linux Distribution Package available in Debian 2.2r4. The fixed ssh-nonfree/ssh-socks Linux Distribution Packages are available in version 1.2.27-6.2 for use with Debian 2.2 (potato) and version 1.2.27-8 for use with the Debian unstable/testing distribution. Note that the new ssh-nonfree/ssh-socks Linux Distribution Packages remove the setuid bit from the ssh binary, disabling rhosts-rsa authentication. If you need this functionality, run chmod u+s /usr/bin/ssh1 after installing the new Linux Distribution Package.

The remote host is missing an update to ssh-nonfree, ssh-socks announced via advisory DSA 086-1.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
