CVE-2019-19624

An out-of-bounds read vulnerability was discovered in OpenCV. This flaw can be exploited when a small, carefully crafted image is loaded by an application linked to OpenCV. A remote attacker could exploit this flaw, causing a denial of service by causing the application to crash or read sensitive information from memory.

This issue did not affect the versions of OpenCV as shipped with Red Hat Enterprise Linux 6, and 7 as they did not include support for DIS optflow algorithm. This issue affects OpenCV as shipped with Red Hat Enterprise Linux 8. However, the package has been built with C++ standard library hardening (_GLIBCXX_ASSERTIONS) that enables range checks for C++ arrays, vectors, and strings. This leads to an application exit due to an assertion statement and prevents the out-of-bounds read to be exploitable.
