Description David Jorm 2014-08-29 07:08:24 UTC

It was found that seed.py, salt-ssh and salt-cloud read files from predictable file names in /tmp. The contents of these files were then used as input to other processes, or directly executed. A local attacker could overwrite these files with malicious versions before they are read by salt, potentially leading to a variety of impacts, including code execution. If salt is running as root (which is the default), code execution as root may be possible.
