CVE-2018-11490
Last modified
CVE-2018-11490 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. 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.. EPSS estimates a 2.48% chance of exploitation in the next 30 days.
