Debian Security Advisory DSA-3420-1 [email protected]
https://www.debian.org/security/ Salvatore Bonaccorso
December 15, 2015 https://www.debian.org/security/faq
Package : bind9
CVE ID : CVE-2015-8000
Debian Bug : 808081
It was discovered that the BIND DNS server does not properly handle the
parsing of incoming responses, allowing some records with an incorrect
class to be accepted by BIND instead of being rejected as malformed.
This can trigger a REQUIRE assertion failure when those records are
subsequently cached. A remote attacker can exploit this flaw to cause a
denial of service against servers performing recursive queries.
For the oldstable distribution (wheezy), this problem has been fixed
in version 1:9.8.4.dfsg.P1-6+nmu2+deb7u8.
For the stable distribution (jessie), this problem has been fixed in
version 1:9.9.5.dfsg-9+deb8u4.
We recommend that you upgrade your bind9 packages.
