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.

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.

Integer signedness error in MiniUPnP MiniUPnPc v1.4.20101221 through v2.0 allows remote attackers to cause a denial of service or possibly have unspecified other impact.

Integer signedness error in the ExecuteSoapAction function in the SOAPAction handler in the HTTP service in MiniUPnP MiniUPnPd 1.0 allows remote attackers to cause a denial of service (incorrect memory copy) via a SOAPAction header that lacks a " (double quote) character, a different vulnerability than CVE-2013-0230.

The ProcessSSDPRequest function in minissdp.c in the SSDP handler in MiniUPnP MiniUPnPd before 1.4 allows remote attackers to cause a denial of service (service crash) via a crafted request that triggers a buffer over-read.

The ExecuteSoapAction function in the SOAPAction handler in the HTTP service in MiniUPnP MiniUPnPd 1.0 allows remote attackers to cause a denial of service (NULL pointer dereference and service crash) via a SOAPAction header that lacks a # (pound sign) character, a different vulnerability than CVE-2013-0230.

Stack-based buffer overflow in the ExecuteSoapAction function in the SOAPAction handler in the HTTP service in MiniUPnP MiniUPnPd 1.0 allows remote attackers to execute arbitrary code via a long quoted method.

A Denial Of Service vulnerability in MiniUPnP MiniUPnPd through 2.1 exists due to a NULL pointer dereference in copyIPv6IfDifferent in pcpserver.c.

A Denial Of Service vulnerability in MiniUPnP MiniUPnPd through 2.1 exists due to a NULL pointer dereference in GetOutboundPinholeTimeout in upnpsoap.c for rem_port.

A Denial Of Service vulnerability in MiniUPnP MiniUPnPd through 2.1 exists due to a NULL pointer dereference in GetOutboundPinholeTimeout in upnpsoap.c for int_port.

The updateDevice function in minissdpd.c in MiniUPnP MiniSSDPd 1.4 and 1.5 allows a remote attacker to crash the process due to a Use After Free vulnerability.

Uninitialized stack variable vulnerability in NameValueParserEndElt (upnpreplyparse.c) in miniupnpd < 2.0 allows an attacker to cause Denial of Service (Segmentation fault and Memory Corruption) or possibly have unspecified other impact

MiniUPnPd has information disclosure use of snprintf()
