Versions affected: BIND 9.7.0 -> BIND 9.10.1-P1. Also, b1 and rc1 development versions of the upcoming BIND maintenance releases (9.9.7b1 & rc1, 9.10.2b1 & rc1) are affected. BIND versions 9.9.6, 9.9.6-P1, 9.10.1, and 9.10.1-P1 will terminate consistently with an assertion in zone.c, but previous affected versions may exhibit unpredictable behavior, including server crashes, due to the use of an improperly initialized variable. Severity: High, but requires specific conditions. Exploitable: Remotely, under limited circumstances.

Other CVEs are fixed in 9.10.3: BIND 9.10.3 BIND 9.10.3 is a maintenance release and addresses bugs found in BIND 9.10.2 and earlier, as well as the security flaws described in CVE-2015-4620, CVE-2015-5477, CVE-2015-5722, and CVE-2015-5986. 56000 2 randy.macleod 2015-10-29 14:29:19 +0000 Kai submitted a patch to do: bind: 9.10.2-P4 -> 9.10.3 but Ross asked to patch only the specific fixes to address CVEs. This may be a policy error in that bind-9.10.3 is a bug-fix only release and oe-core should accept it for oe-core-2.0.1 at least. 56063 3 kai.kang 2015-10-31 02:39:07 +0000 (The tag v9_10_2_P4 on gitweb of https://source.isc.org/git/bind9.git could not open, so list the commits as follow.)
