GLSA-200704-14 : FreeRADIUS: Denial of Service
Medium Nessus Plugin ID 25059
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200704-14 (FreeRADIUS: Denial of Service)
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.
SolutionAll FreeRADIUS users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-dialup/freeradius-1.1.6'
