The PR corrects the check which was introduced in #5332 where
position
is checked to be within boundaries of file. However the checkposition > currentSizeInBytes - start
:start
, andsize
of the slice is lesser thanstart
position.position
is relative tostart
hence there can be data which could be further sliced but asstart
is subtracted fromsize
then it might fail.This PR avoids subtracting
start
from availablesize
as theposition
for slicing is already relative to the start hence just checking if theposition
is lesser than thesize
confirms the boundary.
