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.
