Ipswitch Means Business

A while back I was fuzzing with Hzzp and found a remote format string vulnerability in Ipswitch’s WS_FTP. But, I couldn’t find a security contact for Ipswitch. I waited a few months and made the vulnerability public. The day afterwards, a representative from Ipswitch contacted me and I explained why I hadn’t contacted them previously. He was eager to get the vulnerability fixed and made the comment that they’ll need to do a better job publicizing the security contact information. I was happy to have had received a more professional, non-automated email from someone who seemed to care about the security of their company’s product.

I didn’t worry too much about the update process. I know it can take some companies months or even years to release new patches for vulnerabilities in their products, which most of the time is completely unreasonable. Then, a little more than two weeks later, I received an email from that same Ipswitch representative informing me that a new release of WS_FTP was available and the date in the Help->About window should say Sept 18th (10 days after we discussed the vulnerability). What an excellent example of how vendors should handle security issues within their products.

Fast response, efficient security policy, good business. Thanks Ipswitch!

Linux Kernel Bashing

This summer may have caused a few burden’s on linux administrators. By all the patching necessary to keep their systems out of the hands of those who would choose to exploit it, unless your using something like Ksplice, you’ve more than likely rebooted many times already. Well, here is one more reason to wake this early this morning…

New exploits for the “Linux NULL pointer dereference due to incorrect proto_ops initializations” vulnerability have been released, here and here. I just tried the second one out myself on a (currently) fully updated Ubuntu Jaunty workstation, with (_default_) successful results.

linux@ubuntu:~/2009-proto_ops$ sh run.sh
run.c: In function ‘main’:
run.c:13: warning: missing sentinel in function call
padlina z lublina!
# id
uid=0(root) gid=0(root) groups=4(adm),20(dialout),24(cdrom),46(plugdev)
# exit
linux@ubuntu:~/2009-proto_ops$

A reliable local root exploit for that affects all linux kernels 2.x. Feels like 2003 all over again :X

Major Browsers Pwnd

0day exploits for Internet Explorer, Firefox, and Safari were used to own machines at the Pwn2Own contest @ CanSecWest 2009. Is now the time for someone to port Windows 3.1 to MIPS and install a good telnet client? Roffles.

The R(evolution) of Bug Hunters

Getting real money for computer security research is making its way from early development and ideas to mainstream, and bug hunters probably have mixed feelings, like teenagers. Its an interesting concept that might actually work. What will become of the vulnerability market when something like this becomes popular?

Either way, these guys are basically saying no more freeloading, Mr. Vendor.

DJBDNS Security Broken

According to this thread, DJBDNS’s security has officially been broken. A patch is available and the reward for the bug by Mr. Bernstein will be awarded to Matthew Dempsky. Quoting from the thread:

“If the administrator of example.com publishes the example.com DNS data through tinydns and axfrdns, and includes data for sub.example.com transferred from an untrusted third party, then that third party can control cache entries for example.com, not just sub.example.com. This is the result of a bug in djbdns pointed out by Matthew Dempsky. (In short, axfrdns compresses some outgoing DNS packets incorrectly.)

Even though this bug affects very few users, it is a violation of the expected security policy in a reasonable situation, so it is a security hole in djbdns. Third-party DNS service is discouraged in the djbdns documentation but is nevertheless supported. Dempsky is hereby awarded $1000.

The next release of djbdns will be backed by a new security guarantee. In the meantime, if any users are in the situation described above, those users are advised to apply Dempsky’s patch and requested to accept my apologies. The patch is also recommended for other users; it corrects the bug without any side effects. A copy of the patch appears below.

—D. J. Bernstein

Research Professor, Computer Science, University of Illinois at Chicago”

I still believe Georgi Guninski’s bug was enough for a reward, but oh well. I wonder what the “new security guarentee” will be, anyway.

Yeah, it is true. I guess some programming errors are more serious than others, so lets give these guys a break: I also suppose the dark clouds gathered for all the recent DDoS characters, too.

Adobe Acrobat, at least the reader, has been owned. Again. So Surprising.

The good news is that Xpdf probably isn’t vulnerable :)

Kaspersky Injected

Kaspersky’s USA website was hacked by SQL injection. Maybe they should hire some virus writers to secure their website, or better yet, a good penetration testing team.
