"Notes for BIND 9.11.32
Feature Changes

    DNSSEC responses containing NSEC3 records with iteration counts
    greater than 150 are now treated as insecure. [GL #2445]

    The maximum supported number of NSEC3 iterations that can be
    configured for a zone has been reduced to 150. [GL #2642]

    The implementation of the ZONEMD RR type has been updated to match
    RFC 8976. [GL #2658]

Notes for BIND 9.11.31
Security Fixes

    A malformed incoming IXFR transfer could trigger an assertion
    failure in named, causing it to quit abnormally. (CVE-2021-25214)

    ISC would like to thank Greg Kuechle of SaskTel for bringing this
    vulnerability to our attention. [GL #2467]

    named crashed when a DNAME record placed in the ANSWER section
    during DNAME chasing turned out to be the final answer to a client
    query. (CVE-2021-25215)

    ISC would like to thank Siva Kakarla for bringing this vulnerability
    to our attention. [GL #2540]

    When a server's configuration set the tkey-gssapi-keytab
    or tkey-gssapi-credential option, a specially crafted GSS-TSIG query
    could cause a buffer overflow in the ISC implementation of SPNEGO
    (a protocol enabling negotiation of the security mechanism used for
    GSSAPI authentication). This flaw could be exploited to crash named
    binaries compiled for 64-bit platforms, and could enable remote code
    execution when named was compiled for 32-bit platforms.
    (CVE-2021-25216)

    This vulnerability was reported to us as ZDI-CAN-13347 by Trend
    Micro Zero Day Initiative. [GL #2604]

Feature Changes

    The ISC implementation of SPNEGO was removed from BIND 9 source
    code. Instead, BIND 9 now always uses the SPNEGO implementation
    provided by the system GSSAPI library when it is built with GSSAPI
    support. All major contemporary Kerberos/GSSAPI libraries contain
    an implementation of the SPNEGO mechanism. [GL #2607]

Notes for BIND 9.11.30

The BIND 9.11.30 release was withdrawn after a backporting bug was
discovered during pre-release testing. ISC would like to acknowledge the
assistance of Natan Segal of Bluecat Networks.2"
