|Gentoo Linux Security Advisory
Title: FreeRADIUS: Denial of Service (GLSA 200704-14)
Date: April 17, 2007
A memory leak has been discovered in FreeRADIUS, possibly allowing for a Denial of Service.
FreeRADIUS is an open source RADIUS authentication server implementation.
Vulnerable: < 1.1.6
Unaffected: >= 1.1.6
Architectures: All supported architectures
The Coverity Scan project has discovered a memory leak within the handling of certain malformed Diameter format values inside an EAP-TTLS tunnel.
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.
There is no known workaround at this time.
All FreeRADIUS users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=net-dialup/freeradius-1.1.6"
