Post Memory Corruption Memory Analyzer What is it? ----------- Pmcma is a tool aimed at determining if a given software bug is an exploitable vulnerability by automatically writing an exploit for it. Like every powerful tool made by human beings, it is double edged : it can be used for good or evil. Is this tool for me ? --------------------- Pmcma has a wide range of applications, depending on your use of computer software. As an advanced user, you may experience software bugs in the form of crashes you are able to repeat and would like to report those bugs to software maintainers. Very often, sadly, they will not take your bug request very seriously until you prove them it may have serious security implications. In this case, attaching a pmcma output to your bug report may convince them to fix the bug (or not, if pmcma rules it out as non exploitable ;) As a system administrator, you may find Proof of Concepts or even proper exploits disclosed in public places such as security mailing lists or security websites and wonder if your own systems would be affected by simple modifications of those public codes (that usually never work "as is" anywhere but on the computer of their author ;) As a software developer or maintainer, you may experience or be reported segmentation faults in your software. Pmcma helps you determine what is happening at assembly level and determine which bugs are in fact vulnerabilities and should be fixed first. As a computer security enthusiast, you may want to learn more about software exploitation and experiment. Way to go ! As a security expert or software hacker well versed in exploit writing, you may want to automate reverse engineering as much as possible to spend your time on what is specific to the particular exploit you are writing. As a script kiddie, you may have found a piece of code you don't understand on the internet, but are nonetheless decided to go to jail. In all those cases, and surely many others, Pmcma was probably made for you. Supported platforms ------------------- Currently, pmcma is known to work on x86 and x86_64 intel cpus. Pmcma currently works on GNU/Linux as well as Android. It has been tested on several Ubuntu, Debian, Fedora and Gentoo distributions in both 32bit and 64bit.
