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.
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.
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.
An issue was discovered in giflib through 5.1.4. DumpScreen2RGB in gif2rgb.c has a heap-based buffer over-read.
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.
The DGifDecompressLine function in dgif_lib.c in GIFLIB (possibly version 3.0.x), as later shipped in cgif.c in sam2p 0.49.4, has a heap-based buffer overflow because a certain CrntCode array index is not checked. This will lead to a denial of service or possibly unspecified othe...
The DGifDecompressLine function in dgif_lib.c in GIFLIB (possibly version 3.0.x), as later shipped in cgif.c in sam2p 0.49.4, has a heap-based buffer overflow because a certain "Private->RunningCode - 2" array index is not checked. This will lead to a denial of service or possibl...
Multiple use-after-free and double-free vulnerabilities in gifcolor.c in GIFLIB 5.1.2 have unspecified impact and attack vectors.
Heap-based buffer overflow in util/gif2rgb.c in gif2rgb in giflib 5.1.2 allows remote attackers to cause a denial of service (application crash) via the background color index in a GIF file.
Heap-based buffer overflow in giffix.c in giffix in giflib 5.1.1 allows attackers to cause a denial of service (program crash) via crafted image and logical screen width fields in a GIF file.
