similar to: [PATCH] kbdintctxt->nreq test

The following patch (relative to -current) makes PAM a proper kbd-interactive citizen. There are a few limitations (grep for todo), but the code seems to work OK for protocols 1 & 2 with and without privsep. Please have a play! auth2-pam.c is based on code from FreeBSD. Index: auth2-chall.c =================================================================== RCS file:

Below is a new PAM kbd-int diff based on FreeBSD's code. This code makes PAM kbd-int work with privilege separation. Contrary to what I have previously stated - it *does* handle multiple prompts. What it does not handle is multiple passes through the PAM conversation function, which would be required for expired password changing. I would really appreciate some additional eyes over the

The following is a patch (based on FreeBSD code) which gets kbd-int working with privsep. It moves the kbd-int PAM conversation to a child process and communicates with it over a socket. The patch has a limitation: it does not handle multiple prompts - I have no idea how common these are in real-life. Furthermore it is not well tested at all (despite my many requests on openssh-unix-dev@). -d

1. Versions affected: 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 and later are not affected. OpenSSH 3.2 and later prevent privilege escalation if UsePrivilegeSeparation is enabled in sshd_config. OpenSSH 3.3 enables

I'm trying to understand the code around PAM support in auth2.c and auth2-chall.c. I'm working with the OpenSSH 3.7.1p2 sources on FreeBSD 4.x. The scenario I'm trying to make work is SSH login to a captive accout for users in a RADIUS database but whose login does not appear in /etc/passwd or getpwnam(). I understand that if the username is not found in getpwnam(), then the

Hello all, during tests of my SecurID patch I found a small mistake (maybe) in initialization of kbd-int devices. When kbdintctxt->device->init_ctx(authctxt) returns NULL whole challenge response authentication is stopped regardless availability of next devices. Small patch solving this situation is attached. ____________________________________________________________ Vyzkou?ejte pohodl?

-----BEGIN PGP SIGNED MESSAGE----- Hi, I''ve got several replies, thank you for them. Let me summarize: o Many people say there is a PAMified version of ssh available at ftp://ftp.replay.com/pub/crypto/redhat/SRPMS (the source) ftp://ftp.replay.com/pub/crypto/redhat/i386 (Intel binaries) (there are analogous paths for the other architectures). The packages are made by Jan

When we installed OpenSSH 2.1.1p4 on our Solaris systems, our users noticed that it did not honor password expiration consistently with other Solaris login services. The patch below is against OpenSSH 2.2.0p1 and adds support for PAM password changes on expiration via pam_chauthtok(). A brief summary of changes: auth-pam.c: * change declaration of pamh to "static pam_handle_t *pamh",

Hi Timo, Periodic segfaults with doveadm proxy list: root at director1:~) doveadm proxy list doveadm(root): Error: LIST failed: Disconnected Segmentation fault (core dumped) Sometimes it's just the 'LIST failed' error, other times it's the error with the segfault. Usually the first attempt to call it works, subsequent attempts fail. I've attached a strace log of it in

Hello, in the BSD Authentication system the login script can request environment variables to be set/unset. The call to auth_close() in auth-passwd.c does change the current environment, but those changes are lost for the child environment. It would be really useful to add some kind of mechanism to get those changes into the child environment. I've added two possible solutions. Both

As posted, here is an updated patch which allows openssh to be built with non-selinux config. (Hi openssh guys, forwarding this to you incase you interested including it into the devel version of openssh. Please let us know if you have any suggestions or changes that need to be made) Regards Nigel Kukard On Thu, Sep 02, 2004 at 04:11:54PM -0400, Daniel J Walsh wrote: > New SSH patch. >
