CVSS v3.1
Official Description
Array index error in gd_gif_in.c in the GD Graphics Library (libgd) before 2.0.35 allows user-assisted remote attackers to cause a denial of service (crash and heap corruption) via large color index values in crafted image data, which results in a segmentation fault.
Technical Analysis
CVE-2007-3476 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
