This update for bind fixes the following issues :

Fix two assertion failures that can lead to a remote denial of service attack :

  - CVE-2016-1285: An error when parsing signature records     for DNAME can lead to named exiting due to an assertion     failure. (bsc#970072)

  - CVE-2016-1286: An error when parsing signature records     for DNAME records having specific properties can lead to     named exiting due to an assertion failure in resolver.c     or db.c. (bsc#970073)

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2016:0601 advisory.

    The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols.
    BIND includes a DNS server (named); a resolver library (routines for applications to use when interfacing     with DNS); and tools for verifying that the DNS server is operating correctly.

    Security Fix(es):

    * A denial of service flaw was found in the way BIND parsed signature records for DNAME records. By     sending a specially crafted query, a remote attacker could use this flaw to cause named to crash.
    (CVE-2016-1286)

    * A denial of service flaw was found in the way BIND processed certain control channel input. A remote     attacker able to send a malformed packet to the control channel could use this flaw to cause named to     crash. (CVE-2016-1285)

    Red Hat would like to thank ISC for reporting these issues.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to the versions of the bind packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - A denial of service flaw was found in the way BIND     constructed a response to a query that met certain     criteria. A remote attacker could use this flaw to make     named exit unexpectedly with an assertion failure via a     specially crafted DNS request packet.(CVE-2016-2776)

  - A denial of service flaw was found in the way BIND     processed certain control channel input. A remote     attacker able to send a malformed packet to the control     channel could use this flaw to cause named to     crash.(CVE-2016-1285)

  - A flaw was found in the way BIND performed DNSSEC     validation. An attacker able to make BIND (functioning     as a DNS resolver with DNSSEC validation enabled)     resolve a name in an attacker-controlled domain could     cause named to exit unexpectedly with an assertion     failure.(CVE-2015-4620)

  - A flaw was found in the way BIND handled requests for     TKEY DNS resource records. A remote attacker could use     this flaw to make named (functioning as an     authoritative DNS server or a DNS resolver) exit     unexpectedly with an assertion failure via a specially     crafted DNS request packet.(CVE-2015-5477)

  - A denial of service flaw was found in the way BIND     handled queries for NSEC3-signed zones. A remote     attacker could use this flaw against an authoritative     name server that served NCES3-signed zones by sending a     specially crafted query, which, when processed, would     cause named to crash.(CVE-2014-0591)

  - A denial of service flaw was found in the way BIND     parsed certain malformed DNSSEC keys. A remote attacker     could use this flaw to send a specially crafted DNS     query (for example, a query requiring a response from a     zone containing a deliberately malformed key) that     would cause named functioning as a validating resolver     to crash.(CVE-2015-5722)

  - 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     processed certain records with malformed class     attributes. A remote attacker could use this flaw to     send a query to request a cached record with a     malformed class attribute that would cause named     functioning as an authoritative or recursive server to     crash. Note: This issue affects authoritative servers     as well as recursive servers, however authoritative     servers are at limited risk if they perform     authentication when making recursive queries to resolve     addresses for servers listed in NS     RRSETs.(CVE-2015-8000)

  - A denial of service flaw was found in the way BIND     handled responses containing a DNAME answer. A remote     attacker could use this flaw to make named exit     unexpectedly with an assertion failure via a specially     crafted DNS response.(CVE-2016-8864)

  - A denial of service flaw was found in the way BIND     processed a response to an ANY query. A remote attacker     could use this flaw to make named exit unexpectedly     with an assertion failure via a specially crafted DNS     response.(CVE-2016-9131)

  - A denial of service flaw was found in the way BIND     followed DNS delegations. A remote attacker could use a     specially crafted zone containing a large number of     referrals which, when looked up and processed, would     cause named to use excessive amounts of memory or     crash.(CVE-2014-8500)

  - A flaw was found in the way BIND handled trust anchor     management. A remote attacker could use this flaw to     cause the BIND daemon (named) to crash under certain     conditions.(CVE-2015-1349)

  - A denial of service flaw was found in the way BIND     parsed signature records for DNAME records. By sending     a specially crafted query, a remote attacker could use     this flaw to cause named to crash.(CVE-2016-1286)

  - A use-after-free flaw leading to denial of service was     found in the way BIND internally handled cleanup     operations on upstream recursion fetch contexts. A     remote attacker could potentially use this flaw to make     named, acting as a DNSSEC validating resolver, exit     unexpectedly with an assertion failure via a specially     crafted DNS request.(CVE-2017-3145)

  - 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)

  - 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 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 denial of service flaw was discovered in bind     versions that include the 'deny-answer-aliases'     feature. This flaw may allow a remote attacker to     trigger an INSIST assert in named leading to     termination of the process and a denial of service     condition.(CVE-2018-5740)
