CVE-2019-9423

Status: ModifiedHigh (7.8)—
Severity7.8High · CVSS 3.1
Exploitation probability0.29 %higher than 20% of CVEs
Active exploitationNonot in the CISA catalog
Public exploitNot knownno public code found

In opencv calls that use libpng, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with no additional execution privileges required. User interaction is not required for exploitation.
