CVE-2019-19624 (GCVE-0-2019-19624)
Vulnerability from nvd – Published: 2019-12-06 14:26 – Updated: 2024-08-05 02:25
VLAI?
Summary
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.
Severity ?
No CVSS data available.

Vulnerability from nvd – Published: 2018-03-05 23:00 – Updated: 2024-08-05 06:31 Disputed
VLAI?
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 (pixels <= (1<<30)) 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 ?
No CVSS data available.

Vulnerability from cvelistv5 – Published: 2020-01-03 16:57 – Updated: 2024-08-04 19:47
VLAI?
Summary
An exploitable heap buffer overflow vulnerability exists in the data structure persistence functionality of OpenCV, before version 4.2.0. A specially crafted JSON file can cause a buffer overflow, resulting in multiple heap corruptions and potentially code execution. An attacker can provide a specially crafted file to trigger this vulnerability.
Severity ?
8.8 (High)
CWE
- CWE-120 - Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')

CVE-2019-19624 (GCVE-0-2019-19624)
Vulnerability from cvelistv5 – Published: 2019-12-06 14:26 – Updated: 2024-08-05 02:25
VLAI?
Summary
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.
Severity ?
No CVSS data available.

CVE-2018-7713 (GCVE-0-2018-7713)
Vulnerability from cvelistv5 – Published: 2018-03-05 23:00 – Updated: 2024-08-05 06:31 Disputed
VLAI?
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 ?
No CVSS data available.
