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.
An issue was discovered in GetByte function in miniupnp ngiflib version 0.4, allows local attackers to cause a denial of service (DoS) via crafted .gif file (infinite loop).
ngiflib commit 84a75 was discovered to contain a segmentation violation via the function SDL_LoadAnimatedGif at ngiflibSDL.c. This vulnerability is triggered when running the program SDLaffgif.
ngiflib commit fb271 was discovered to contain a segmentation violation via the function "main" at gif2tag.c. This vulnerability is triggered when running the program gif2tga.
ngiflib 0.4 has a heap overflow in GetByteStr() at ngiflib.c:108 in NGIFLIB_NO_FILE mode, GetByteStr() copy memory buffer without checking the boundary.
ngiflib 0.4 has a heap-based buffer overflow in WritePixels() in ngiflib.c when called from DecodeGifImg, because deinterlacing for small pictures is mishandled.

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.

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.
