Research - Discarded

2009-06-01T17:27:00.000-07:00

This section will list potential vulnerabilities that I have discarded.If reporting them to the vendor is easy then you I'll wait for their response before posting.

Firefox - bug 492779
PL_Base64Decode integer overflow
Code changes made: here and here

Looked very promising at first. A common library routine used in many places with a straight forward integer overflow, caused because it multiplied before dividing..Exploitation also looked promising since we could control the amount to overflow the buffer with by using invalid base64 characters to make the decode no-op.

Reason for discarding:
Was unable to trigger it.

Advisories - Published

Vendor: Novell
Severity: High
Type: Remote vulnerability
Published: ZDI-10-001
Discovered: 02-09
Comments: Interesting that Novell patches the vulnerability and releases patch but advisory is not published until several months later. I wonder if many vendors do this.

Vendor: Sun
Product: Solaris - w(1)
Severity: Medium
Published: Sun Alert
Sun Bug: 6821298
Notes: I respect Sun alot, so no further details provided.

Vendor: IBM

muxatmd buffer overflow
4-15-09 iDefense
Bugtraq ID: 34543

libc arbitrary file overwrite
5-20-09 iDefense
Bugtraq ID: 35034
This is also the first bug I have ever sold, was a rather eye-opening experience.
I really would have expected more from developers working on libc.

My research is published giving credit to: 1c239c43f521145fa8385d64a9c32243
(Except my very first few)
