Hello Kurt, Steve, vendors,

  a security flaw was found in the way Paster, a pluggable command-line
when started as root (for example to have access to privileged port) to
serve a
web based application, performed privileges dropping upon startup
(supplementary groups were not dropped properly regardless of the UID, GID
specified in the .ini configuration file or in the --user and --group CL
arguments). A remote attacker could use this flaw for example to read /
root GID accessible files, if the particular web application provided
means for local file manipulation.
