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)
