Debian DLA-1085-1 : libidn2-0 security update

critical Nessus Plugin ID 102924

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that there was an integer overflow vulnerability in libidn2-0's Punycode handling (an encoding used to convert Unicode characters to ASCII) which would have allowed attackers to cause a remote denial of service.

For Debian 7 'Wheezy', this issue has been fixed in libidn2-0 version 0.8-2+deb7u1.

We recommend that you upgrade your libidn2-0 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.
