From $URL: Two new patch releases for the stable versions of collectd have been released. They fix various bugs, including one which can be used for a Denial of Service (DoS) attack. Users are encouraged to upgrade.
This is fixed in collectd-4.10.2-r2, which is already in the tree. Feel free to remove collectd-4.10.1-r4 from CVS (it may take a day or so until I get back to my ssh keys :o). No stable ebuilds on any arch.
PS. Merry Christmas (if applicable)! :)
