ngiflib 0.4 has a heap overflow in GetByte() at ngiflib.c:70 in NGIFLIB_NO_FILE mode, GetByte() reads memory buffer without checking the boundary. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.

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. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.

MiniUPnP ngiflib 0.4 has a NULL pointer dereference in GifIndexToTrueColor in ngiflib.c via a file that lacks a palette. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.

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. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity.

ngiflib 0.4 has a heap-based buffer overflow in WritePixel() in ngiflib.c when called from DecodeGifImg, because deinterlacing for small pictures is mishandled. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available.

GifIndexToTrueColor in ngiflib.c in MiniUPnP ngiflib 0.4 has a Segmentation fault. Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.

ngiflib.c in MiniUPnP ngiflib 0.4 has a heap-based buffer over-read in GifIndexToTrueColor. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.

ngiflib.c in MiniUPnP ngiflib 0.4 has a stack-based buffer overflow in DecodeGifImg. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.

The DecodeGifImg function in ngiflib.c in MiniUPnP ngiflib 0.4 does not consider the bounds of the pixels data structure, which allows remote attackers to cause a denial of service (WritePixels. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available.

The DecodeGifImg function in ngiflib.c in MiniUPnP ngiflib 0.4 lacks certain checks against width and height, which allows remote attackers to cause a denial of service (WritePixels heap-based buffer. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available.
