The MHDhttpunescape 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 (CVE-2013-7038).
Stack-based buffer overflow in the MHDdigestauthcheck function in libmicrohttpd before 0.9.32, when MHDOPTIONCONNECTIONMEMORY_LIMIT is set to a large value, allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long URI in an authentication header (CVE-2013-7039).
