Debian DLA-291-1 : libidn security update

High Nessus Plugin ID 85418


The remote Debian host is missing a security update.


Adam Sampson found a vulnerability in GNU Libidn, library that implements the IETF IDN specifications. Libdin incorrectly handled invalid UTF-8 input, causing it to bad free(). This issue was introduced by the fix for CVE-2015-2059.

For Debian 6 'Squeeze', this issue has been fixed in the 1.15-2+deb6u2 version of libidn.

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.


Upgrade the affected packages.
