CVE-ID: CVE-2018-11490

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the DGifDecompressLine function in dgif_lib.c in GIFLIB because a certain "Private->RunningCode - 2" array index is not checked. A remote attacker can trigger a heap-based buffer overflow and execute arbitrary code on the target system.
