Reachable Assertion

CVE-2018-7712

High
7.5/10

Summary

** DISPUTED ** The validateInputImageSize function in `modules/imgcodecs/src/loadsave.cpp` in OpenCV allows remote attackers to cause a denial of service (assertion failure) because `(size.height <= (1<<20))` may be false. Note: according to the maintainers, "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". SCA AppSec team researched the issue and found out that it is still a security issue because even though the exceptions are raised on purpose, indeed it causes the application to crash.
