CVE-2013-7039

CVE-2013-7039 describes a stack-based buffer overflow in the MHD_digest_auth_check function of libmicrohttpd versions prior to 0.9.32. This vulnerability allows remote attackers to trigger a denial of service or potentially execute arbitrary code by sending a long URI within an authentication header, specifically when MHD_OPTION_CONNECTION_MEMORY_LIMIT is set to a large value. With a CVSS score of 5.1, it has a network attack vector and high attack complexity, leading to partial confidentiality, integrity, and availability impacts. There is no evidence of active exploitation, publicly available exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
