Evaluator Impact

Per https://bugs.launchpad.net/ubuntu/+source/clamav/+bug/365823 A clean install of clamav-milter (0.95.1+dfsg-1ubuntu1.1) causes the root directory to become owned by the clamav user. This was witnessed breaking ssh chroot environment. TEST CASE: - purge any existing clamav-milter installation, make sure you don't have any old /etc/init.d/clamav-milter init script around - check root directory's owner (should be root:root) - sudo apt-get install clamav-milter (the last one in Jaunty is 0.95.1+dfsg-1ubuntu1.1) - after installing the package, clamav-milter will start automatically (at least 'init.d/clamav-milter start' will execute) - check the root directory's owner:
