Synopsis ========
A memory leak has been discovered in FreeRADIUS, possibly allowing for a Denial of Service.
Background ==========
FreeRADIUS is an open source RADIUS authentication server implementation.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-dialup/freeradius < 1.1.6 >= 1.1.6
Description ===========
The Coverity Scan project has discovered a memory leak within the handling of certain malformed Diameter format values inside an EAP-TTLS tunnel.
Impact ======
A remote attacker could send a large amount of specially crafted packets to a FreeRADIUS server using EAP-TTLS authentication and exhaust all memory, possibly resulting in a Denial of Service.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All FreeRADIUS users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-dialup/freeradius-1.1.6"
