View 5 Replies View RelatedSecurity :: Address Space Randomization On 2.6.28-15-generic Ubuntu 9.04 - Finding Base Address?
Sep 14, 2009Im an academic (university networks and security lecturer) studying/teaching network and operating system security, and inspired by the work of Hovav Shacham set about testing ASLR on linux. Principley I did this by performing a brute force buffer overflow attack on Fedora 10 and Ubuntu 9. I did this by writting a little concurrent server daemon which accidently on purpose didnt do bounds checking.
I then wrote a client to send it a malicious string brute forcing guessed addresses which caused a return-to-libc to the function usleep with a parameter of 16m causing a delay of 16 seconds as laid out in [URL] Once I hit the delay I new I had found the function and could calculate delta_mmap allowing me to create a standard chained ret-to-libc attack. All of that works fine. However .... To complete my understanding I am trying establish where I can find the standard base address for ubuntu 9 (and other distros) for the following, taken from Shacham:-
Quote:
[code]....
/proc/uid/maps gives me some information but not the base address ldd also gives me the randomised starting address for sections in the user address space but neither gives me the base address. Intrestingly ... when a run ldd with aslr on for over (about) 100 times and checked the start point of libc I determined that the last 3 (least significant) hex digits were always 0's and the fist 4 (most significant) where between 0xB7D7 and 0xB7F9. To me this indicated that bits 22-31 were fixed and bits 12-21 were randomized with bits 11-0 fixed. Although even that doesnt define the boundaries observed correctly.
Note: I am replicating the attack to provide signatures to detect it using IDS, and for teaching purposes. I am NOT a hacker and if needed to could reply from my .ac.uk email address as verification.

View 1 Replies View RelatedHardware :: Finding Out The Original MAC Address Of An Interface?
Jun 29, 2009How can i find out what mac address had been configured by factory default. I changed my mac address with
Code:
ip link set addrs 00:01:02:03:04:05
and now want to have the original one back. I'm having some trouble with a gigabit LAN PCI Express card. Namely the 89156 from delock. Output of dmesg
Code:
r8169 Gigabit Ethernet driver 2.3LK-NAPI loaded
[ 4.137225] r8169 0000:02:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
[ 4.137268] r8169 0000:02:00.0: setting latency timer to 64
[ 4.137346] r8169 0000:02:00.0: irq 27 for MSI/MSI-X
[code]....
So the card was recognized by the kernel. The driver was loaded and everything fine.... should be! But after assigning an ip addr and setting the nic up with
Code:
ip addr add 192.168.1.1/24 dev eth1
ip link set dev eth1 up
the kernel complained about something like that
Code:
?SISTEM? Can't assign address Also I could not find anything useful on the net finally the readme gave me some. So i changed the MAC address and everything was fine. The nic came up and got an ip through dhclient.i want to know why the old/original mac address didn't work. But even after reboot the new mac address remains. All I know the old one begun with 7b. how to get the original mac of a nic?
General :: KPackageKit Not Finding Correct IP Address
Aug 15, 2010I have installed Kubuntu Lucid x86 10.4 LTS for the first time. Has anyone got a link that explains how KPackageKit gets the IP address of the repositories? I can install packages using sudo apt-get install xxx OK . KpackageKit tells me I have updates from the repositories. I can select them all and apply , but I get an error that it can't find the repository under a 192.168.100.129:8080 address . Which is not a surprise . I am using mirror.optus.net as a repository and can ping it fine on the command line. So is there somewhere else that KPackageKit maps IP addreses ? I have tried another mirror mirror.aarnet.edu.au and got similar results. My local sub-net is not 192.168.100 and have tried setting fixed IP on the local sub-net and different DHCP addresses and still the same error.

Ubuntu Networking :: Static IP Address And The Install Configures For A DHCP Configured Address - Network Not Starting
Dec 16, 2010Version 10.04 LTS. Installed desktop version and network worked but I needed a static IP address and the install configures for a DHCP configured address. I tried changing to static address using the System->Preferences->Network Connections application but was unable to get the system to come up with the network up.
So I manually modified the /etc/network/interfaces and the /etc/resolv.conf files. I restart the system but when I do an ifconfig, I don't see a configured IP address on eth0 (only the loopback address). If I run /sbin/ifup eth0 everything then works fine and ifconfig shows the correct address bound to eth0.

Networking :: Dynamic IP Address With PTR Record Versus Fixed IP Address Without?
May 7, 2010I am running my own Postfix mail server. Some time ago I noticed that most email was rejected because of the server's dynamic IP address. So I got a fixed IP address. However then I noticed that some mails got rejected due to failing the reverse DNS check. So my ISP told me to get a range of IP addresses and they could then create a PTR record for one of those addresses. That is now running but it turns out that the IP address used for the PTR record is a ... dynamic IP address. So Spamhaus PBL rejects my emails again.
