Rating: important
References: #908994
Affected Products:
  • SUSE Linux Enterprise Software Development Kit 12

  • An update that fixes one vulnerability is now available.

    Description:


    This update of bind to 9.9.6P1 fixes bugs and also the following security
    issue:

    A flaw in delegation handling could be exploited to put named into an
    infinite loop. This has been addressed by placing limits on the number of
    levels of recursion named will allow (default 7), and the number of
    iterative queries that it will send (default 50) before terminating a
    recursive query (CVE-2014-8500, bnc#908994).

    The recursion depth limit is configured via the "max-recursion-depth"
    option, and the query limit via the "max-recursion-queries" option.

    Also the rpz2 patch was removed as it is no longer maintained.
