CVE-ID: CVE-2019-16249
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
OpenCV 4.1.1 has an out-of-bounds read in hal_baseline::v_load in core/hal/intrin_sse.hpp when called from computeSSDMeanNorm in modules/video/src/dis_flow.cpp.
MitigationUpdate the affected package opencv to the latest version.

CVE-ID: CVE-2019-19624
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe 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.
MitigationUpdate the affected package opencv to the latest version.

CVE-ID: CVE-2023-2617
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the DecodedBitStreamParser::decodeByteSegment() function in qrcode/decoder/decoded_bit_stream_parser.cpp. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
