freeradius vulnerabilities


A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 17.04
  • Ubuntu 16.04 LTS
  • Ubuntu 14.04 LTS
Summary


Several security issues were fixed in FreeRADIUS.

Software description

  • freeradius - high-performance and highly configurable RADIUS server
Details


Guido Vranken discovered that FreeRADIUS incorrectly handled memory when
decoding packets. A remote attacker could use this issue to cause
FreeRADIUS to crash or hang, resulting in a denial of service, or possibly
execute arbitrary code.
