8.8

CVSS v3.1

Official Description

The DecodeGifImg function in ngiflib.c in MiniUPnP ngiflib 0.4 does not consider the bounds of the pixels data structure, which allows remote attackers to cause a denial of service (WritePixels heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted GIF file, a different vulnerability than CVE-2018-10677.

Technical Analysis

CVE-2018-10717 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation does not require any privileges, though user interaction (Required) is needed, which slightly reduces the risk of mass automated attacks.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.8.

From a weakness classification perspective (CWE-787): Out-of-bounds write vulnerabilities can lead to data corruption, crashes, or arbitrary code execution.
