Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) NULL pointer dereference

EUVDB-ID: #VU30956

Risk: Medium

CVSSv4.0: [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2019-14493

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

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.

2) Out-of-bounds read

EUVDB-ID: #VU35495

Risk: Medium

CVSSv4.0: [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2019-16249

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The 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.

Mitigation

Update the affected package opencv to the latest version.

3) Out-of-bounds read

EUVDB-ID: #VU30559

Risk: Medium

CVSSv4.0: [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2019-19624

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

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.

Mitigation

Update the affected package opencv to the latest version.

Risk: Medium

CVSSv4.0: [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2023-2617

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

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