Puppet forked privilege escalation
|puppet-forked-priv-escalation (73445)||High Risk|
Puppet could allow a local attacker to gain elevated privileges on the system, caused by the improper dropping of group permissions when a process is forked. A local attacker could exploit this vulnerability to execute arbitrary code on the system with root privileges.
Upgrade to the latest version of Puppet (2.6.14, 2.7.11, 2.0.3 Enterprise or later), available from the Puppet Labs Web site. See References.
