A vulnerability in FreeRADIUS can lead to arbitrary code execution or Denial of Service by authenticated users.
|Package||net-dialup/freeradius on all architectures|
|Affected versions||< 2.2.5|
|Unaffected versions||>= 2.2.5|
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.
There is no known workaround at this time.
All FreeRADIUS users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-dialup/freeradius-2.2.5"
