Description Hanno Böck gentoo-dev 2014-12-08 18:22:36 UTC
unbound is vulnerable to a Denial of service attack through specially crafted DNS records causing an infinite loop of delegations.

Fixed in upstream's 1.5.1.
Comment 1 Mike Gilbert gentoo-dev 2014-12-08 19:52:45 UTC
Bug 530928 is pretty minor, and should probably not block this.
Comment 2 Tim Harder gentoo-dev 2014-12-08 22:14:27 UTC
Feel free to stabilize if you want, just note bug #531068.
Comment 3 Yury German Gentoo Infrastructure gentoo-dev Security 2015-01-31 19:39:35 UTC
