Debian DLA-1084-1 : libidn security update

critical Nessus Plugin ID 102923

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that there was an integer overflow vulnerability in libidn's Punycode handling (an encoding used to convert Unicode characters to ASCII) which would have allowed remote attackers to cause a denial of service.

For Debian 7 'Wheezy', this issue has been fixed in libidn version 1.25-2+deb7u3.

We recommend that you upgrade your libidn 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.
