CVE-2018-7713 (GCVE-0-2018-7713)

Vulnerability from cvelistv5 – Published: 2018-03-05 23:00 – Updated: 2024-08-05 06:31

Summary

The validateInputImageSize function in modules/imgcodecs/src/loadsave.cpp in OpenCV 3.4.1 allows remote attackers to cause a denial of service (assertion failure) because (size.width <= (1<<20)) may be false. Note: “OpenCV CV_Assert is not an assertion (C-like assert()), it is regular C++ exception which can raised in case of invalid or non-supported parameters.

Severity ?
