Last modified

CVE-2018-7712 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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.height <= (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.. EPSS estimates a 2.31% chance of exploitation in the next 30 days.
