Affected versions are subject to an Out-Of-Bounds Read in the `general_LumaToYUV444` function. This Out-Of-Bounds Read occurs because processing is done on the `in` variable without checking if it contains data of sufficient length. Insufficient data for the `in` variable may cause errors or crashes. This issue has been addressed in versions 2.11.0 and 3.0.0-beta3. Users are advised to upgrade. There are no known workarounds for this issue.
