   An update that fixes two vulnerabilities is now available.

Description:


   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. (bsc#1041216)
