    3. Description:
    
    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):
    
    * bind: BIND does not sufficiently limit the number of fetches performed
    when processing referrals (CVE-2020-8616)
    
    * bind: A logic error in code which checks TSIG validity can be used to
    trigger an assertion failure in tsig.c (CVE-2020-8617)
    
    For more details about the security issue(s), including the impact, a CVSS
    score, acknowledgments, and other related information, refer to the CVE
    page(s) listed in the References section.
