find could crash listing a file with a nonsense timestamp
Brief
It now checks the time conversion before formatting.
Notes
abb6d3e98484 (tb@, 2026-08-26 00:47:59 PDT). usr.bin/find/ls.c. source-changes: check localtime() return before calling strftime. landry saw find dir -ls crash with filesystem corruption. dgl reproduced with a nonsense timestamp. ok deraadt. Not labeled SECURITY FIX.
