Description

The remote host is affected by the vulnerability described in GLSA-200606-22 (aRts: Privilege escalation)

artswrapper fails to properly check whether it can drop privileges
accordingly if setuid() fails due to a user exceeding assigned resource
limits.

Impact :

Local attackers could exploit this vulnerability to execute arbitrary
code with elevated privileges. Note that the aRts package provided by
Gentoo is only vulnerable if the artswrappersuid USE-flag is enabled.

Workaround :

There is no known workaround at this time.
