This version changes the way how the 'ntsec' setting is figured out. This is needed to accomplish newer (developer) versions of Cygwin which have set 'ntsec' by default. These versions are identifiable by a API version greater than or equal to 0.56 (see first number in parenthesis on `uname -r'). IMPORTANT NOTICE: ======================================================================== Today, 2002-08-01, there is evidence that the official OpenSSH-3.4p1 source tar archive on ftp.openbsd.org has been trojaned. This tar archive hasn't been used to create the Cygwin version in the official Cygwin net distribution. The Cygwin version is created from the tar archive I downloaded on 2002-06-26 which was not trojaned. All versions of OpenSSH as part of the Cygwin net distribution are unaffected by the problem on ftp.openssh.org. ======================================================================== The following comment from the 3.4p1-1 announcement still applies: ======================================================================== This version allows to use privilege separation in a slightly restricted way. Since privilege separation is consisting of two independent parts (preauth, postauth) and only the postauth part requires descriptors passing, this version enables the usage of preauth privilege separation in Cygwin. Note that this doesn't create an additional sshd process as described in the README.privsep file and note that this isn't still as secure as fully-fledged privilege separation but it's a good start. ======================================================================== Official Release Message: ==================================================================== OpenSSH 3.4 has just been released. It will be available from the mirrors listed at http://www.openssh.com/ shortly. OpenSSH is a 100% complete SSH protocol version 1.3, 1.5 and 2.0 implementation and includes sftp client and server support. We would like to thank the OpenSSH community for their continued support and encouragement. Changes since OpenSSH 3.3: ============================ Security Changes: ================= All versions of OpenSSH's sshd between 2.9.9 and 3.3 contain an input validation error that can result in an integer overflow and privilege escalation. OpenSSH 3.4 fixes this bug. In addition, OpenSSH 3.4 adds many checks to detect invalid input and mitigate resource exhaustion attacks. OpenSSH 3.2 and later prevent privilege escalation if UsePrivilegeSeparation is enabled in sshd_config. OpenSSH 3.3 enables UsePrivilegeSeparation by default. Reporting Bugs: =============== - please read http://www.openssh.com/report.html and http://bugzilla.mindrot.org/ OpenSSH is brought to you by Markus Friedl, Niels Provos, Theo de Raadt, Kevin Steves, Damien Miller and Ben Lindstrom. ==================================================================== To update your installation, click on the "Install Cygwin now" link on the http://cygwin.com/ web page.
