Debian DLA-476-1 : libidn security update

High Nessus Plugin ID 91196


The remote Debian host is missing a security update.


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.

For Debian 7 'Wheezy', these problems have been fixed in version 1.25-2+deb7u1.

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.


Upgrade the affected packages.
