Description Arvid Requate univentionstaff 2016-10-06 19:16:00 CEST
Upstream Debian package version 1:9.8.4.dfsg.P1-6+nmu2+deb7u11 fixes

* buffer.c in named does not properly construct responses, which allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a crafted query. (CVE-2016-2776)

Not affected by CVE-2016-2775.

Package: bind9

Branch: ucs_3.2-0
Scope: errata3.2-8

r73253 | Bug #40319: bind9 YAML
 bind9.yaml

FYI: All other bind9 versions were rebuilt as well as each UCS release has a different version of OpenSSL - I did a successful update from 3.2 → 3.3 → 4.1
