during my seminar of advanced exploitation techniques (SEAT, [1]) i developed some methods to crack into system via DMA (e.g. via firewire). as part of this i developed a program that steals loaded ssh private keys from ssh-agents. i was astonished to find that the keys are not immediately removed from the agent when a timeout occurs, but only the next time the agent is queried via its socket. i

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

ssh-agent is a great tool that is often misconfigured with respect to agent forwarding. How many people running ssh-agent and doing a ssh -A have the very same public keys in ~/.ssh/authorized_keys of the machine they are coming from? ssh(1) is very clear in its warning about enabling agent forwarding. The simple act of prompting the user before using the key would enable them to determine

Hi all! I do not know openssh patch policy so I am just sending the patch to the mailing list. Sorry for inconvenience. Ssh-agent seems to be too slow if you need to access thousands of servers. This is a simple patch to enable threading in ssh2 authentication. Patch adds "-p numthreads" option and defaults to the number of processors. I've tested it as I could, but

Hi everyone. I have a system where I'd like to give certain users time-limited access to the use of certain SSH private keys without actually exposing the keys. I have the idea of using ssh-agent to do this. The agent would run as a "keyholder" user, and group permissions on the UNIX-domain socket would allow read-write by both that account and the actual ssh user. Right now,

Have you tried Asterisk 13? The bridging mechanism has been completely rewritten on Asterisk 12, so there's no longer channel masquerading and zombie channels.

There''s a field in my User model that sometimes needs bulk updates: User.update_all("cluster = #{new_cluster}", "cluster = # {current_cluster}") Now, suppose user with id 37 is affected by that particular update_all and updates his profile: 1. user 37 is read 2. update_all happens and changes 37''s cluster asynchronously 3. user 37 is saved

I would like to be able to manage different db connections per request. I''ve gotten this working by using establish_connection in a before_filter on all controllers. My concern is whether or not there could be a race condition where two or more overlapping requests might reset the SQL connection. Is there any serialization logic which will prevent this? Must I introduce this logic

Thank you Paul for your response. Perhaps I can give a bit more info: RS/6000 H50 w/AIX 4.3.2 running Samba 2.0.5a PIII-450 NT4sp4 w/128MB I indicated yesterday that a race condition appeared to be happening. I later remembered that I turned on level2 oplocks on two read only shares as the last tunings we did before this began to happen. I got the info from the Speed.txt document in hopes of

Sadly, we have discovered another line level interrupt race condition in Xen-4.1. The result was that an outstanding un-eoi''d interrupt at the IO-APIC resulted in the mptsas controller offlining the root filesystem. This is now two separate IO-APIC bugs found recently. 1) Cisco C210 M2 server - EOI Broadcast Suppression, io_apci_ack=old 2) Dell R710 - No EOI Broadcast Suppression,

Block drivers like nbd and rbd unlock struct request_queue->queue_lock in their request_fn. I'd like to do the same in virtio_blk. After happily posting the patch, Michael Tsirkin pointed out an issue that I can't explain. This may affect existing block drivers that unlock the queue_lock too. What happens when the block device is removed (hot unplug or kernel module unloaded) while

Hi, So, the issue is a fairly common one: Network doesn''t work for like a minute or so after a live migration. The setup is a debian wheezy dom0 with xen 4.1.2 running 3.6.11 kernel. The domU is a Ubuntu 12.04 with a 3.2 kernel. The networking setup uses bridges on the dom0. I also made sure that the bridge forwarding delay is set to 0. The VM doesn''t initiate any network
