It was discovered that FreeRADIUS did not correctly handle certain malformed attributes. A remote attacker could exploit this flaw and cause the FreeRADIUS server to crash, resulting in a denial of service.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
