Description Pedro Sampaio 2020-01-09 14:50:45 UTC
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.
