Debian DLA-2116-1 : libpam-radius-auth security update

high Nessus Plugin ID 133877

Synopsis

The remote Debian host is missing a security update.

Description

A vulnerability was found in pam_radius: the password length check was done incorrectly in the add_password() function in pam_radius_auth.c, resulting in a stack based buffer overflow.

This could be used to crash (DoS) an application using the PAM stack for authentication.

For Debian 8 'Jessie', this problem has been fixed in version 1.3.16-4.4+deb8u1.

We recommend that you upgrade your libpam-radius-auth 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 libpam-radius-auth package.
