Severity:high
Title:FreeRADIUS: Arbitrary code execution
Date:06/15/2014
Bugs: #501754
ID:201406-12

Synopsis

A vulnerability in FreeRADIUS can lead to arbitrary code execution or Denial of Service by authenticated users.

Background

FreeRADIUS is an open source RADIUS authentication server.

Affected packages

Package Vulnerable Unaffected Architecture(s)
net-dialup/freeradius < 2.2.5 >= 2.2.5 All supported architectures

Description

Large passwords can trigger a stack-based buffer overflow in FreeRADIUS’s rlm_pap module when authenticating against an LDAP server.

Impact

An authenticated user could set a specially crafted long password, possibly leading to arbitrary code execution or a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All FreeRADIUS users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=net-dialup/freeradius-2.2.5"
