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.
