{"id":"GHSA-8849-5h85-98qw","summary":"Out-of-bounds Write in OpenCV","details":"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.
