Conky is an advanced, highly configurable system monitor for X.
A privilege escalation vulnerability due to an insecure temporary file was found in Conky.
A local attacker could possibly overwrite arbitrary files with the privileges of the user running Conky.
There is no known workaround at this time.
All Conky users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-admin/conky-1.8.1-r2"
