Debian Security Advisory DSA-2573-1 security@debian.org
http://www.debian.org/security/ Luciano Bello
November 10, 2012 http://www.debian.org/security/faq
- - -------------------------------------------------------------------------
Package : radsecproxy
Vulnerability : SSL certificate verification weakness
Problem type : remote
Debian-specific: no
CVE ID : CVE-2012-4523 CVE-2012-4566
Ralf Paffrath reported that Radsecproxy, a RADIUS protocol proxy, mixed up
pre- and post-handshake verification of clients. This vulnerability may
wrongly accept clients without checking their certificate chain under
certain configurations.
Raphael Geissert spotted that the fix for CVE-2012-4523 was incomplete,
giving origin to CVE-2012-4566. Both vulnerabilities are fixed with this
update.
Notice that this fix may make Radsecproxy reject some clients that are
currently (erroneously) being accepted.
For the stable distribution (squeeze), these problems have been fixed in
version 1.4-1+squeeze1.
For the testing distribution (wheezy), these problems have been fixed in
version 1.6.2-1.
For the unstable distribution (sid), these problems have been fixed in
version 1.6.2-1.
We recommend that you upgrade your radsecproxy packages.
