Debian DLA-347-1 : putty security update

medium Nessus Plugin ID 87068

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that PuTTY's terminal emulator did not properly validate the parameter to the ECH (erase characters) control sequence, allowing a denial of service and possibly remote code execution.

For the oldoldstable distribution (squeeze), this problem has been fixed in version 0.60+2010-02-20-1+squeeze4.

For the oldstable (wheezy) and stable (jessie) distributions, this problem will be fixed soon.

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.
