RedHat: Moderate: freeradius security update RHSA-2009:1451-01
Summary
FreeRADIUS is a high-performance and highly configurable free Remote
Authentication Dial In User Service (RADIUS) server, designed to allow
centralized authentication and authorization for a network.
An input validation flaw was discovered in the way FreeRADIUS decoded
specific RADIUS attributes from RADIUS packets. A remote attacker could use
this flaw to crash the RADIUS daemon (radiusd) via a specially-crafted
RADIUS packet. (CVE-2009-3111)
Users of FreeRADIUS are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. After installing the
update, radiusd will be restarted automatically.
Summary
