Descriptions

Heap buffer overflow in Skia in Google Chrome prior to 116.0.5845.96 allowed a remote attacker who had compromised the renderer process to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)

When deserializing an SkPath, there is some basic validation performed to ensure that the contents are consistent. This validation does not use safe integer types, or perform additional validation, so it's possible for a large path to overflow the point count, resulting in an unsafe SkPath object.
