Revision a60a66e409c265b2944f18bf43581c146812586d authored by Patrick Steinhardt on 01 December 2022, 14:45:40 UTC, committed by Junio C Hamano on 05 December 2022, 06:14:16 UTC
When parsing an attributes line, we need to allocate an array that holds all attributes specified for the given file pattern. The calculation to determine the number of bytes that need to be allocated was prone to an overflow though when there was an unreasonable amount of attributes. Harden the allocation by instead using the `st_` helper functions that cause us to die when we hit an integer overflow.
