Positive Technologies (AI Summary)

CVSS v3.1

7.8

High

Base vector

AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions: CImg versions prior to v.220

Description: The issue is related to a heap-based buffer over-read in the load bmp function in CImg.h, which occurs when loading a specially crafted bmp image. This can potentially allow an attacker to impact the confidentiality, integrity, and availability of protected information.

Recommendations: For versions prior to v.220, consider disabling the load bmp function in CImg.h until a patch is available to prevent potential exploitation. Restrict the loading of bmp images from untrusted sources to minimize the risk of exploitation.
