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

2.  Impact Information


FreeRADIUS is an open source RADIUS authentication server.


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


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

3.  Resolution Information


There is no known workaround at this time.


All FreeRADIUS users should upgrade to the latest version:

Code Listing 3.1: Resolution

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