Debian DSA-3578-1 : libidn - security update

High Nessus Plugin ID 91140

Synopsis

The remote Debian host is missing a security-related update.

Description

It was discovered that libidn, the GNU library for Internationalized Domain Names (IDNs), did not correctly handle invalid UTF-8 input, causing an out-of-bounds read. This could allow attackers to disclose sensitive information from an application using the libidn library.

Solution

Upgrade the libidn packages.

For the stable distribution (jessie), this problem has been fixed in version 1.29-1+deb8u1.
