Package : unbound
Version : 1.4.17-3+deb7u3
CVE ID : CVE-2017-15105
Debian Bug : 887733

Ralph Dolmans and Karst Koymans found a flaw in the way unbound
validated wildcard-synthesized NSEC records. An improperly validated
wildcard NSEC record could be used to prove the non-existence
(NXDOMAIN answer) of an existing wildcard record, or trick unbound
into accepting a NODATA proof.

For more information please refer to the upstream advisory at
https://unbound.net/downloads/CVE-2017-15105.txt.

For Debian 7 "Wheezy", these problems have been fixed in version
1.4.17-3+deb7u3.

We recommend that you upgrade your unbound packages.

these updates to your system and frequently asked questions can be
