Gentoo Linux Security Advisory

Title: FreeRADIUS: Arbitrary code execution (GLSA 201406-12)
Severity: high
Exploitable: remote
Date: June 15, 2014
Bug(s): #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: net-dialup/freeradius
Vulnerable: < 2.2.5
Unaffected: >= 2.2.5
Architectures: 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:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=net-dialup/freeradius-2.2.5"
