similar to: [Bug 304] New: ssh-keysign memory freeing bug

Hello Steve, Hello OpenSSH-portable developers, I am building OpenSSH for our (EBCDIC-based) BS2000 mainframe operating system, and I noticed you do the same for OS/390. Because my initial ssh port was based on IBM's OSS port (ssh-1.2.2 or some such), I thought it was fair enough to help with a little co-operation; we might come up with a unified EBCDIC patch which could be contributed to

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

The latter versions of openssh (3.4,3.5 and 3.6.1) all seem to suffer from a broken ssh-keysign binary. This causes HostbasedAuthentication to fail. We have installed 3.6.1p1 on a Solaris 8 machine using openssl-0.9.6i. This fails thusly ssh server <......some \digits removed - a key perhaps?> ssh_keysign: no reply key_sign failed a at server's password For version 3.4p1 we patched

Hi, At the n2k10 OpenBSD network hackathon, I finally got some time to clean up and rewrite the ssh(1) client multiplexing code. The attached diffs (one for portable OpenSSH, one for OpenBSD) are the result, and they need some testing. The revised multiplexing code uses a better protocol between the master and slave processes and I even bothered to write it up :) It tracks the control sockets

The included patch for openssh 3.0.2p1 implements overlapping read requests for the sftp client. It should be able to handle weird cases such as shriking files and reordered responses. This is only the first shot, and I'd be happy for any comments. I plan to implement something similar for the write path if this works out well. The maximum number of outstanding requests is quite high at

key is freed outside of the if that checks if key is NULL therefore, NULL could be sent to the key_free function which will not handle it correctly. The fix is to move key_free to a place where you know key is not NULL. This patch moves the key_free call. This entire set of patches passed the regression tests on my system. Bug found by Coverity.

The problem I am seeing was introduced between 6.4p1 and 6.5p1 (and still exists in 6.6p1). With HostbasedAuthentication/EnableSSHKeysign turned on, I am seeing one of two sets of messages: no matching hostkey found ssh_keysign: no reply key_sign failed and not a valid request ssh_keysign: no reply key_sign failed Then in either case two password prompts: bowman at HOST.math.utah.edu's

Hi all, I recently made a patch to openssh 4.1p1 to allow it to use the in-kernel key management provided by 2.6.12 or later Linux kernels. I've attached the patch (which is still only a proof-of-concept, for instance its very verbose right now) to this mail. Now, my question is, is this a completely insane idea and would (a later version of) the patch have a chance of making it into the

Hi, I applied the following minor diff to preserve the value of the extern variable across calls to process_sign_request2() in ssh-agent.c. I've no idea if the attachment of the attachment will come out correctly so a cvs diff is also attached. Regards, Alistair -------------- next part -------------- An embedded message was scrubbed...

this is the proposed gssapi diff against OpenSSH-current (non-portable). note: if this goes in, the old krb5 auth (ssh.com compatible) will be removed. please comment. jakob Index: auth.h =================================================================== RCS file: /home/hack/jakob/mycvs/sshgss/auth.h,v retrieving revision 1.1.1.2 retrieving revision 1.3 diff -u -r1.1.1.2 -r1.3 --- auth.h

I use ssh in a batch environment (www.pbspro.com) and am using host based authentication to allow sshes between some resources. When I converted from openssh 3.1 to newer versions (up to an including 3.8 where ssh-keysign was moved to a standalone binary) I had issues with ssh-keysign failing with the error "bad fd". A little exploring showed that this was happening because in the
