“The apcd package as shipped in Debian GNU/Linux 2.1 is
vulnerable to a symlink attack.”

“The apcd package as shipped in Debian GNU/Linux 2.1 is
vulnerable to a symlink attack. If the apcd process gets a SIGUSR1
signal it will dump its status to /tmp/upsstat. However this file

“This has been fixed in version 0.6a.nr-4slink1. We recommend
you upgrade your apcd package immediately.”
