giflib 3.0.x - Heap-Based Buffer Overflow in DGifDecompressLine

Title source: llm
STIX 2.1

Description

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 possibly unspecified other impact.
