- Vendors Description


Details:
========
There are several buffer overflow vulnerabilities which can be triggered when 
loading a specially crafted profile into RUMBA. RUMBA is lacking in it's ability 
to safely copy values out of the profile file; it places too much trust on the 
length values calculated or supplied within these files being under a certain 
length limit.
