Debian Security Advisory                             security () debian org

Package: apcd
Vulnerability type: symlink attack
Debian-specific: no

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 is not opened
safely, which makes it a good target for a symlink attack.

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

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.
