The MHD_http_unescape function in libmicrohttpd before 0.9.32 might allow remote attackers to obtain sensitive information or cause a denial of service (crash) via unspecified vectors that trigger an out-of-bounds read.

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.
