Positive Technologies (AI Summary)

CVSS v3.1

7.5

High

Base vector

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

Name of the Vulnerable Software and Affected Versions: OpenCV version 3.4.1

Description: The issue is related to the validateInputImageSize function in modules/imgcodecs/src/loadsave.cpp, which can cause a denial of service due to an assertion failure when the condition (pixels <= (1<<30)) is false. It is noted that OpenCV CV Assert is a regular C++ exception that can be raised for invalid or non-supported parameters, rather than a traditional assertion.

Recommendations: As a temporary workaround, consider adding input validation to ensure that the number of pixels does not exceed the maximum allowed value of (1<<30). At the moment, there is no information about a newer version that contains a fix for this vulnerability.
