-----BEGIN PGP SIGNED MESSAGE-----
Sendmail, Inc., and the Sendmail Consortium announce the availability
of sendmail 8.11.6 and 8.12.0.Beta19.
These new versions fix a security problem reported by SecurityFocus
regarding command line processing. This vulnerability is present in
sendmail open source versions between 8.10.0 and 8.11.5 as well as all
8.12.0.Beta versions. Therefore, sendmail 8.12.0.Beta users should upgrade
to 8.12.0.Beta19.
The problem was not present in 8.10 or earlier versions. However, as
always, we recommend using the latest version. Note that this problem is
not remotely exploitable.
Please send bug reports to sendmail-bugs
sendmail.org and general
feedback to sendmail
sendmail.org.
The versions can be found at:

You need either the gzip'ed version (.gz) or the compressed version
(.Z). The .sig files contain the PGP signature of the tar files
(after uncompressing). The PGP signatures were created using the
Sendmail Signing Key/2001, available on the web site
(http://www.sendmail.org/) or on the public key servers.

8.11.6/8.11.6 2001/08/20
SECURITY: Fix a possible memory access violation when specifying
out-of-bounds debug parameters. Problem detected by
Cade Cairns of SecurityFocus.
Avoid leaking recipient information in unrelated DSNs. This could
happen if a connection is aborted, several mails had been
scheduled for delivery via that connection, and the timeout
is reached such that several DSNs are sent next. Problem
noted by Dileepan Moorkanat of Hewlett-Packard.
Fix a possible segmentation violation when specifying too many
wildcard operators in a rule. Problem detected by
Werner Wiethege.
Avoid a segmentation fault on non-matching Hesiod lookups. Problem
noted by Russell McOrmond of flora.ca
