Hi, I'm seeking approval for the upload of poco 1.3.6p1-5. I received a patch for CVE-2014-0350 (#746637) from Maxime Chatelle, who prepared an upload for unstable. Debdiff is attached, dsc is available on mentors: http://mentors.debian.net/debian/pool/main/p/poco/poco_1.3.6p1-5.dsc I don't see problems with the patch but would like approval from the release team before going ahead. If we don't apply the patch now, poco 1.3.6p1-4 should be removed from testing. Thanks, -- Cristian Greco GPG key ID: 0xCF4D32E4
