Vulnerabilidades

Buffer Overflow vulnerability in giflib v.5.2.2 allows a remote attacker to cause a denial of service via the EGifGCBToExtension overwriting an existing Graphic Control Extension block without validating its allocated size.

Giflib contains a double-free vulnerability that is the result of a shallow copy in GifMakeSavedImage and incorrect error handling. The conditions needed to trigger this vulnerability are difficult but may be possible.

Heap-based Buffer Overflow vulnerability in openEuler giflib on Linux. This vulnerability is associated with program files gif2rgb.C. This issue affects giflib: through 5.2.2.

Giflib Project v5.2.2 is vulnerable to a heap buffer overflow via gif2rgb.

Buffer Overflow vulnerability in GifLib Project GifLib v.5.2.1 allows a local attacker to obtain sensitive information via the DumpSCreen2RGB function in gif2rgb.c

giflib v5.2.1 was discovered to contain a segmentation fault via the component getarg.c.

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 commit 5e7292 was discovered to contain an infinite loop via the function DecodeGifImg at ngiflib.c.

An issue was discovered in ngiflib 0.4. There is SEGV in SDL_LoadAnimatedGif when use SDLaffgif. poc : ./SDLaffgif CA_file2_0

A memory leak (out-of-memory) in gif2rgb in util/gif2rgb.c in giflib 5.1.4 allows remote attackers trigger an out of memory exception or denial of service via a gif format file.

There is a heap-buffer-overflow in GIFLIB 5.2.1 function DumpScreen2RGB() in gif2rgb.c:298:45.

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.

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.

An issue was discovered in giflib through 5.1.4. DumpScreen2RGB in gif2rgb.c has a heap-based buffer over-read.

ngiflib 0.4 has a heap-based buffer over-read in GifIndexToTrueColor in ngiflib.c.

MiniUPnP ngiflib 0.4 has a NULL pointer dereference in GifIndexToTrueColor in ngiflib.c via a file that lacks a palette.

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.

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.

In GIFLIB before 2019-02-16, a malformed GIF file triggers a divide-by-zero exception in the decoder function DGifSlurp in dgif_lib.c if the height field of the ImageSize data structure is equal to zero.

ngiflib.c in MiniUPnP ngiflib 0.4 has an infinite loop in DecodeGifImg and LoadGif.
