Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Out-of-bounds read (CVE-ID: CVE-2019-19624)

The vulnerability allows a remote non-authenticated attacker to #BASIC_IMPACT#.

An out-of-bounds read was discovered in OpenCV before 4.1.1. Specifically, variable coarsest_scale is assumed to be greater than or equal to finest_scale within the calc()/ocl_calc() functions in dis_flow.cpp. However, this is not true when dealing with small images, leading to an out-of-bounds read of the heap-allocated arrays Ux and Uy.


2) Out-of-bounds read (CVE-ID: CVE-2019-14491)

The vulnerability allows a remote non-authenticated attacker to #BASIC_IMPACT#.

An issue was discovered in OpenCV before 3.4.7 and 4.x before 4.1.1. There is an out of bounds read in the function cv::predictOrdered<cv::HaarEvaluator> in modules/objdetect/src/cascadedetect.hpp, which leads to denial of service.


3) Out-of-bounds read (CVE-ID: CVE-2019-14492)

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

An issue was discovered in OpenCV before 3.4.7 and 4.x before 4.1.1. There is an out of bounds read/write in the function HaarEvaluator::OptFeature::calc in modules/objdetect/src/cascadedetect.hpp, which leads to denial of service.


4) NULL pointer dereference (CVE-ID: CVE-2019-14493)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dreference error in function cv::XMLParser::parse at modules/core/src/persistence.cpp. A remote attacker can perform a denial of service (DoS) attack.
