Debian DLA-957-1 : bind9 security update
high Nessus Plugin ID 100477
Language:
Synopsis
The remote Debian host is missing a security update.Description
CVE-2017-3136Oleg Gorokhov of Yandex discovered that BIND does not properly handle certain queries when using DNS64 with the 'break-dnssec yes;' option, allowing a remote attacker to cause a denial of service.
CVE-2017-3137
It was discovered that BIND makes incorrect assumptions about the ordering of records in the answer section of a response containing CNAME or DNAME resource records, leading to situations where BIND exits with an assertion failure. An attacker can take advantage of this condition to cause a denial of service.
CVE-2017-3138
Mike Lalumiere of Dyn, Inc. discovered that BIND can exit with a REQUIRE assertion failure if it receives a null command string on its control channel. Note that the fix applied in Debian is only applied as a hardening measure. Details about the issue can be found at https://kb.isc.org/article/AA-01471 .
For Debian 7 'Wheezy', these problems have been fixed in version 1:9.8.4.dfsg.P1-6+nmu2+deb7u16.
We recommend that you upgrade your bind9 packages.
