Debian DLA-1763-1 : putty security update

critical Nessus Plugin ID 124283

Synopsis

The remote Debian host is missing a security update.

Description

Multiple vulnerabilities were found in the PuTTY SSH client, which could result in denial of service and potentially the execution of arbitrary code. In addition, in some situations random numbers could potentially be re-used.

For Debian 8 'Jessie', these problems have been fixed in version 0.63-10+deb8u2.

We recommend that you upgrade your putty packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
