Package : bind9
Version : 1:9.8.4.dfsg.P1-6+nmu2+deb7u17
CVE ID : CVE-2017-3142 CVE-2017-3143
CVE-2017-3142
An attacker who is able to send and receive messages to an authoritative
DNS server and who has knowledge of a valid TSIG key name may be able to
circumvent TSIG authentication of AXFR requests via a carefully constructed
request packet. A server that relies solely on TSIG keys for protection
with no other ACL protection could be manipulated into:
- providing an AXFR of a zone to an unauthorized recipient
- accepting bogus NOTIFY packets
CVE-2017-3143
An attacker who is able to send and receive messages to an authoritative
DNS server and who has knowledge of a valid TSIG key name for the zone and
service being targeted may be able to manipulate BIND into accepting an
unauthorized dynamic update.
For Debian 7 "Wheezy", these problems have been fixed in version
1:9.8.4.dfsg.P1-6+nmu2+deb7u17.
We recommend that you upgrade your bind9 packages.
