giflib: CVE-2018-11490

Severity: High · CVSS 8.8CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Published: May 23, 2018, 12:00:00 AM UTC

EPSS: 2.45% · Oct 27, 2026

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.
