Comment(by ild):
I'm pleased that you are interested in Avalanche. Cause I'm its
developer:)
OK, I'll try to describe it. We are currently working on adding new
features to Avalanche, and those exploits were found using these features.
They are probably not yet stable, but already quite useful.
You'll have to checkout the sources from SVN:
$ svn checkout !http://avalanche.googlecode.com/svn/branches/separate-
analysis avalanche
Then build Avalanche (you'll need autotools for that)
$ ./autogen.sh[[BR]]
$ ./configure --prefix=<path to avalanche install directory>[[BR]]
$ make[[BR]]
$ make install
If everything is build fine, run Avalanche. You may find the actual
command line
[http://code.google.com/p/avalanche/wiki/Separate_analysis_speed_up#pbc_dump_(parrot)
here].
There is a special new option for Avalanche: '--input-filter-file=<mask
file>'. If it is not specified, Avalanche considers all the data in the
input file as tainted. In this case the analysis may take too much time
and won't be effective. If this option is specified, then only those
positions that are listed in the mask file are considered to hold the
tainted data. It may significantly speed up the analysis and allows
Avalanche to explore certain parts of the application ignoring other
parts.
Other options should be described
[http://code.google.com/p/avalanche/wiki/Using_Avalanche here]
That was a very brief description. Consult the
[http://code.google.com/p/avalanche/w/list Avalanche wiki] for further
information and feel free to ask any questions. You may write to
[email protected]. I'm interested in any feedback.
Hope you'll find Avalanche useful.
