"This update for libmicrohttpd fixes the following issues :

  - CVE-2013-7038: The MHD_http_unescape function in
    libmicrohttpd might have allowed remote attackers to
    obtain sensitive information or cause a denial of
    service (crash) via unspecified vectors that trigger an
    out-of-bounds read. (bsc#854443)

  - CVE-2013-7039: Stack-based buffer overflow in the
    MHD_digest_auth_check function in libmicrohttpd, when
    MHD_OPTION_CONNECTION_MEMORY_LIMIT is set to a large
    value, allowed remote attackers to cause a denial of
    service (crash) or possibly execute arbitrary code via a
    long URI in an authentication header. (bsc#854443)

  - Fixed various bugs found during a 2017 audit, which are
    more hardening measures and not security issues.
