Debian DSA-3658-1 : libidn - security update

Medium Nessus Plugin ID 93254


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


Hanno Boeck discovered multiple vulnerabilities in libidn, the GNU library for Internationalized Domain Names (IDNs), allowing a remote attacker to cause a denial of service against an application using the libidn library (application crash).


Upgrade the libidn packages.

For the stable distribution (jessie), these problems have been fixed in version 1.29-1+deb8u2.
