Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read in the decodegridtile process. An attacker can cause a heap out-of-bounds read by supplying a crafted image file that triggers an irot-induced tile-coordinate underflow. Remediation Upgrade libheif to version 1.23.1 o...
