Comments: To: scientific-linux-errata@fnal.gov

Synopsis:	Moderate: cyrus-sasl security update and bug fix update
Issue date:	2007-09-04
CVE Names:	CVE-2006-1721

A bug was found in cyrus-sasl's DIGEST-MD5 authentication mechanism. As
part of the DIGEST-MD5 authentication exchange, the client is expected to
send a specific set of information to the server. If one of these items
(the "realm") was not sent or was malformed, it was possible for a remote
unauthenticated attacker to cause a denial of service (segmentation fault)
on the server. (CVE-2006-1721)

This errata also fixes the following bugs in Scientific Linux 4:

* the Kerberos 5 library included in Red Hat Enterprise Linux 4 was not
thread safe. This update adds functionality which allows it to be used
safely in a threaded application.

* several memory leak bugs were fixed in cyrus-sasl's DIGEST-MD5
authentication plug-in.

* /dev/urandom is now used by default on systems which don't support
hwrandom. Previously, dev/random was the default.

* cyrus-sasl needs zlib-devel to build properly. This dependency
information is now included in the package.
