MiniUPnPd through 2.3.11 Divide-by-Zero DoS via SSDP M-SEARCH MX Header

MiniUPnPd through 2.3.11 built with --strict contains a divide-by-zero vulnerability in ProcessSSDPData() that allows unauthenticated local network attackers to crash the daemon. Attackers can send a single multicast M-SEARCH datagram with MX: 0 and a known ST to port 1900, triggering SIGFPE and denying UPnP IGD service.

CVE-2026-5720 Critical · 9.1 CWE-125 Apr 17, 2026

miniupnpd Integer Underflow SOAPAction Header Parsing

miniupnpd contains an integer underflow vulnerability in SOAPAction header parsing that allows remote attackers to cause a denial of service or information disclosure by sending a malformed SOAPAction header with a single quote. Attackers can trigger an out-of-bounds memory read by exploiting improper length validation in ParseHttpHeaders(), where the parsed length underflows to a large unsigned value when passed to memchr(), causing the process to scan memory far beyond the allocated HTTP request buffer.
