Gentoo Linux Security Advisory
Title: FreeRADIUS: Denial of Service (GLSA 200704-14)
Severity: normal
Exploitable: remote
Date: April 17, 2007
Bug(s): #174292
ID: 200704-14
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: net-dialup/freeradius
Vulnerable: < 1.1.6
Unaffected: >= 1.1.6
Architectures: All supported architectures
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: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=net-dialup/freeradius-1.1.6" |
