The remote NewStart CGSL host, running version MAIN 4.05, has bind packages installed that are affected by multiple vulnerabilities:

  • A flaw was found in the way BIND handled TSIG authentication for dynamic updates. A remote attacker able to communicate with an authoritative BIND server could use this flaw to manipulate the contents of a zone, by forging a valid TSIG or SIG(0) signature for a dynamic update request. (CVE-2017-3143)

  • A flaw was found in the way BIND handled TSIG authentication of AXFR requests. A remote attacker, able to communicate with an authoritative BIND server, could use this flaw to view the entire contents of a zone by sending a specially constructed request packet.
    (CVE-2017-3142)

  • A denial of service flaw was found in the way BIND handled DNSSEC validation. A remote attacker could use this flaw to make named exit unexpectedly with an assertion failure via a specially crafted DNS response.
    (CVE-2017-3139)

  • A denial of service flaw was found in the way BIND handled a query response containing CNAME or DNAME resource records in an unusual order. A remote attacker could use this flaw to make named exit unexpectedly with an assertion failure via a specially crafted DNS response. (CVE-2017-3137)

  • It was found that the lightweight resolver protocol implementation in BIND could enter an infinite recursion and crash when asked to resolve a query name which, when combined with a search list entry, exceeds the maximum allowable length. A remote attacker could use this flaw to crash lwresd or named when using the lwres statement in named.conf. (CVE-2016-2775)

  • A denial of service flaw was found in the way BIND handled query requests when using DNS64 with break- dnssec yes option. A remote attacker could use this flaw to make named exit unexpectedly with an assertion failure via a specially crafted DNS request.
    (CVE-2017-3136)

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
