How to fix?

There is no fixed version for Debian:8 giflib.

NVD Description

Note: Versions mentioned in the description apply only to the upstream giflib package and not the giflib package as distributed by Debian. See How to fix? for Debian:8 relevant fixed versions and status.

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.
