similar to: ssh.c - allocated wrong size for sensitive_data.keys?

Hi, Is there any way to store HostKey in hardware (and delegate the related processing)? I have been using Roumen Petrov's x509 patch for clients, which works via an OpenSSL engine, but it does not seem to support server HostKey: http://roumenpetrov.info/pipermail/ssh_x509_roumenpetrov.info/2012q4/000019.html For PKCS#11, I have found an email on this list from a year back suggesting this

Hello, The following patch avoids a warnign message when using hostbased authentication as root and protocol v1 support has been disabled.

In the current implementation, ssh always uses the hostname supplied by the user directly for the SSHFP DNS record lookup. This causes problems when using the domain search path, e.g. I have "search example.com" in my resolv.conf and then do a "ssh host", I will connect to host.example.com, but ssh will query the DNS for an SSHFP record of "host.", not

Hello all, I recently found myself wanting to run sshd with passphrase-protected host keys rather than the usual unencrypted format, and was somewhat surprised to discover that sshd did not support this. I'm not sure if there's any particular reason for that, but I've developed the below patch (relative to current CVS at time of writing) that implements this. It prompts for the

Hi list, I have no idea if Damien Miller had the time to work on that. I have an initial patch to authenticate using PKCS#11 and ECDSA keys. This requires OpenSSL 1.0.2, prior OpenSSL versions do not expose the required interfaces to override the signature function pointer for ECDSA. The only limitation is that the OpenSSL API misses some cleanup function (finish, for instance), hence I have yet

Hi, About a year and a half ago I brought up the topic of encrypted hostkeys and posted a patch (http://marc.info/?l=openssh-unix-dev&m=132774431906364&w=2), and while the general reaction seemed receptive to the idea, a few problems were pointed out with the implementation (UI issues, ssh-keysign breakage). I've finally had some spare time in which to get back to this, and I've

Below is a patch against the current OpenBSD OpenSSH CVS to workaround a behavior I have observed when converting from SSH 1.2.27 to OpenSSH while using the same old RSA1 host key for protocol 1. In several cases I saw that old SSH sshd reported a host key size of 1024 bits when OpenSSH saw it as 1023 bits. Without the patch, when OpenSSH's ssh client connects to an old SSH sshd it warns

Hello, I need to allow for some people to execute ssh with one shared private key for remote executing command on various machines. However, it is not possible to set group permissions for private keys and it is possible to have just one private key file for one user. Please, is it possible to add patches into openssh development tree like these, so that standard behavior of ssh is not changed,

Hi All. While wandering in auth-pam.c I noticed that there's a few Portable-specific escapees from the xmalloc(foo * bar) cleanup. There's also a "probably can't happen" integer overflow in ssh-rand-helper.c with the memset: num_cmds = 64; - entcmd = xmalloc(num_cmds * sizeof(entropy_cmd_t)); + entcmd = xcalloc(num_cmds, sizeof(entropy_cmd_t));

Hi, experimenting with openssh_cvs on my SCO Unix 3.2v4.2 machine, I had sshd core dumping on me. Tracking this, I found that if a host key is specified in the sshd_config that does not exist (I used "./sshd -d -d -d -f sshd_config" with the shipped sshd_config file, to work around incompatibilities with the installed sshd.com's sshd_config, and I do not have ssh2 host keys on

I'm seeing some extremely odd behavior with solaris. I have a suspicion it's me, but here's the story and maybe someone can suggest an avenue of investigation. This seems to be happening with any release of openssh since at least 2.5.2p1. 1) Problem #1: If SSH protocol 1 is enabled then sshd segfaults right off. This turns out to be because the call to arc4random_stir is

Hello, Due to patent concerns, I compiled a version of openssl with the no-rsa, no-idea, no-rc5 options. I was able to then take this compile of openssl, with the standard openssh-2.1.0 rpms and run it on another machine. Most things seemed to work fine, except I was unable to ssh into the machine. After applying the following patch to the sshd code, a quick test with an ssh session worked:

I'm looking at the code from CVS as of May 21. The statement to allocate the mux state is allocating the size of a pointer, instead of the size of the struct being pointed to. The bug is benign in the original code because the struct has only an int element inside it, but it would corrupt memory if the struct were to be extended. Simple fix here: diff --git a/mux.c b/mux.c index

Hi, OpenSSH 6.9 is almost ready for release, so we would appreciate testing on as many platforms and systems as possible. This release contains some substantial new features and a number of bugfixes. Snapshot releases for portable OpenSSH are available from http://www.mindrot.org/openssh_snap/ The OpenBSD version is available in CVS HEAD: http://www.openbsd.org/anoncvs.html Portable OpenSSH is

I am testing out the grid-plots, but get into a problem making a legend. I have a line plot and some points, following the model in grid.plot.and.legend() i manage to get the points correctly in the legend, but what do I do with the line?

We've run into an interesting dilemma regarding last log information and ssh 4.2p1. In 3.8, we didn't see this problem, but now has cropped up in 4.2. When a user logs in, sshd seems to call 'last' to get the last log information. 'last' then opens the /var/log/wtmp file and processes the information. On some systems, this file can be quite large, and we're seeing
