Markus Friedl announced the release of OpenSSH 3.5 today, the first release since version 3.4 which was made available in late June after the discovery of an input validation error [story]. This error resulted in the "One remote hole in the default install, in nearly 6 years!" referred to on the OpenBSD home page [story]. OpenSSH 3.4 has had no known security holes.
OpenSSH 3.5 is available for download now, and will also be part of the upcoming OpenBSD 3.2 release available on November 1'st. Read on for the release announcement, detailing what's new in this verison.
From: Markus Friedl To: announce AT openbsd.org Subject: OpenSSH 3.5 released Date: Tue, 15 Oct 2002 20:58:07 +0200 OpenSSH 3.5 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 3.4: ============================ * Improved support for Privilege Separation (Portability, Kerberos, PermitRootLogin handling). * ssh(1) prints out all known host keys for a host if it receives an unknown host key of a different type. * Fixed AES/Rijndael EVP integration for OpenSSL < 0.9.7 (caused problems with bounds checking patches for gcc). * ssh-keysign(8) is disabled by default and only enabled if the HostbasedAuthentication option is enabled in the global ssh_config(5) file. * ssh-keysign(8) uses RSA blinding in order to avoid timing attacks against the RSA host key. * A use-after-free bug was fixed in ssh-keysign(8). This bug broke hostbased authentication on several platforms. * ssh-agent(1) is now installed setgid in order to avoid ptrace(2) attacks. * ssh-agent(1) now restricts the access with getpeereid(2) (or equivalent, where available). * sshd(8) no longer uses the ASN.1 parsing code from libcrypto when verifying RSA signatures. * sshd(8) now sets the SSH_CONNECTION environment variable. * Enhanced "ls" support for the sftp(1) client, including globbing and detailed listings. * ssh(1) now always falls back to uncompressed sessions, if the server does not support compression. * The default behavior of sshd(8) with regard to user settable environ variables has changed: the new option PermitUserEnvironment is disabled by default, see sshd_config(5). * The default value for LoginGraceTime has been changed from 600 to 120 seconds, see sshd_config(5). * Removed erroneous SO_LINGER handling.
