Debian DLA-1064-1 : freeradius security update

critical Nessus Plugin ID 102784

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Guido Vranken discovered that FreeRADIUS, an open source implementation of RADIUS, the IETF protocol for AAA (Authorisation, Authentication, and Accounting), did not properly handle memory when processing packets. This would allow a remote attacker to cause a denial of service by application crash, or potentially execute arbitrary code.

For Debian 7 'Wheezy', these problems have been fixed in version 2.1.12+dfsg-1.2+deb7u2.

We recommend that you upgrade your freeradius 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.
