Debian Security Advisory DSA-3854-1 [email protected]

Package : bind9
CVE ID : CVE-2017-3136 CVE-2017-3137 CVE-2017-3138
Debian Bug : 860224 860225 860226
Several vulnerabilities were discovered in BIND, a DNS server
implementation. The Common Vulnerabilities and Exposures project
identifies the following problems:
CVE-2017-3136
Oleg 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 the stable distribution (jessie), these problems have been fixed in
version 1:9.9.5.dfsg-9+deb8u11.
For the unstable distribution (sid), these problems have been fixed in
version 1:9.10.3.dfsg.P4-12.3.
We recommend that you upgrade your bind9 packages.
