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
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.
