similar to: Buffer management bug-fix for 2.5.1p2

This is the 1st revision of the Advisory. This document can be found at: http://www.openssh.com/txt/buffer.adv 1. Versions affected: All versions of OpenSSH's sshd prior to 3.7 contain a buffer management error. It is uncertain whether this error is potentially exploitable, however, we prefer to see bugs fixed proactively. 2. Solution: Upgrade to OpenSSH

Is anybody aware of this? -hc ----- Forwarded message from Alex Lambert <alambert@quickfire.org> ----- 3.7.1 was just released. Two patches for similar issues in a very short timeframe. Who do they think they are -- Microsoft? <grin> apl -------- Original Message -------- Subject: OpenSSH Security Advisory: buffer.adv Date: Wed, 17 Sep 2003 01:13:30 +0200 From: Markus Friedl

Hi, I am trying to create a virtual machine with FC6 inside a Centos 5 (beta) Xen host. I am following the documentation of Fedora[1]. I used the "virt-install" command, and every went fine until the moment to create the partitions on the virtual disk (file "/var/xen/fc6.iso" with 10GB). No matter with option I choose: remove all partitions, remove linux partitions, use

For AIX 53 ML01 I'm getting a "Segmentation fault in buffer_append_space at line 85 in file buffer.c" in sshd after typing my password for a new connection to the AIX 5.3 host. Line 85 is "if (buffer->offset == buffer->end) {". Is this caused by an old bug in buffer_append_space? Regards Rob v.d. Wal

While rototilling packet.c, I did some looking at cipher_encrypt in cipher.c. It ends up that for SSH_CIPHER_NONE in cipher_encrypt, it uses memcpy. However, it also appears that dest and src can be equal in cipher_encrypt. On most sane libc implementations, memcpy == memmove. However, ANSI C makes no such guarantee, and some implementations out there are bound to try to optimize memcpy

I have been trying to install 3.4p1 on a number of machines. Servers on ia64 Linux, i386 Linux and SPARC Solaris are all working like charms. On the other hand, I am having trouble at least with HPUX 11, DEC OSF 5.1 and Unixware: on all those systems, sshd bails out after authentication with an error in buffer_append_space. Here is the output of sshd -d on the UnixWare machine (uname -a:

The current code for channel.c creates an array of Channel structs (initially set to NULL) which is then iterated through, in full, every time a channel needs to be dealt with. If only one channel is in use, which is relatively common, the code still loops through the entire array. This patch creates a linked list of pointers to these structs and the code steps through the linked list. Since

I am talking about Windows Mobile 8 and 8.1 and not CE. Not sure though that the Windows 8 (ARM NT) is similar to Windows Mobile 8 platform. I used the following command to generate the obj file Llc.exe -mtriple=thumbv7-windows -filetype=obj <some_name>.bc The object file generated in the above object doesn't get linked when I try to link it with the windows mobile library as it

Hi Saleem, I have a similar situation - I'd appreciate your inputs on it. I noticed that the obj file generated using llvm does not contain "thumb" instructions. I suspect that is what is causing runtime crash for me. Here's what I've tried - Start with a.c (on my linux machine where I have llvm/clang built as of yesterday) int add(int i, int j) {int k

We have developed a patch that enables changing the SSH window size using the tcp window size as the source. This allows SSH to obtain maximum use of the bandwidth on high BDP links. We also have a page that describes the changes and performance. http://www.psc.edu/~rapier/hpn-ssh/ The patch against CVS is included here.
