Description Vincent Danen 2014-03-05 16:20:19 EST

The amsvis command in the powerpc-utils-python package implements a client-server protocol to exchange Active Memory Sharing information, based on the Python cPickle serialization library.  This could allow an attacker who can connect to amsvis server process (or cause an amsvis client process to connect to them) to execute arbitrary code as the user running the amsvis process.  This update changes the client-server protocol to use JSON instead.
