| radius-radprintrequest-dos (15046) |  Medium Risk |
Description:
GNU Radius (Remote Authentication Dial In User Service) is vulnerable to a denial of service attack, caused by a vulnerability in the rad_print_request function of the lib/logger.c file. By sending a specially-crafted UDP packet that contains only an Acct-Status-Type attribute, a remote attacker could cause the Radius daemon (radiusd) to crash.
Platforms Affected:
- Digital, OSF/1
- GNU, Radius 1.1
Remedy:
Upgrade to the latest version of GNU Radius (1.2 or later), available from the GNU Radius Web page. See References.
