zeertzjq 2336389d23 vim-patch:9.0.2112: [security]: overflow in shift_line ... Problem: [security]: overflow in shift_line Solution: allow a max indent of INT_MAX [security]: overflow in shift_line When shifting lines in operator pending mode and using a very large value, we may overflow the size of integer. Fix this by using a long variable, testing if the result would be larger than INT_MAX and if so, indent by INT_MAX value. Special case: We cannot use long here, since on 32bit architectures (or on Windows?), it typically cannot take larger values than a plain int, so we have to use long long count, decide whether the resulting multiplication of the shiftwidth value * amount is larger than INT_MAX and if so, we will store INT_MAX as possible larges value in the long long count variable. Then we can safely cast it back to int when calling the functions to set the indent (set_indent() or change_indent()). So this should be safe. Add a test that when using a huge value in operator pending mode for shifting, we will shift by INT_MAX closes: vim/vim#13535 6bf131888a Skip the test for now, as it takes too long and requires other fixes.
