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.

Affected configurations

• giflib project giflib (>= 3.0 <= 3.1.1) • sam2p project sam2p 0.49.4 • debian debian linux 10.0 • canonical ubuntu linux 16.04 • canonical ubuntu linux 18.04 • canonical ubuntu linux 19.04
