Security update for dnsdist

This update for dnsdist fixes the following issues:

  • update to 1.8.0

    • Implements dnsdist in SLE15 (jsc#PED-3402)
    • Security fix: fixes a possible record smugging with a crafted DNS query with trailing data (CVE-2018-14663, bsc#1114511)

  • update to 1.2.0 (bsc#1054799, bsc#1054802) This release also addresses two security issues of low severity, CVE-2016-7069 and CVE-2017-7557. The first issue can lead to a denial of service on 32-bit if a backend sends crafted answers, and the second to an alteration of dnsdist’s ACL if the API is enabled, writable and an authenticated user is tricked into visiting a crafted website.
