Jan Dubois 1b549962b2 Fix panic on negative slice indices that underflow after adjustment ... sliceArrayOperator adjusts negative indices by adding Content length, but does not clamp the result. When the absolute value of a negative index exceeds Content length (e.g. .[-99999:3] on a 3-element array), the adjusted index remains negative and causes an out-of-bounds access in the Content slice loop. Extract the adjust-and-clamp logic into clampSliceIndex and use it for both index positions. Reproducer (panics before this fix, returns full array after): echo '[a, b, c]' | yq '.[-99999:3]' Found by OSS-Fuzz via the lima project's FuzzEvaluateExpression target. https://issues.oss-fuzz.com/issues/438776028 Signed-off-by: Jan Dubois <jan@jandubois.com> Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>		2026-04-05 22:35:04 -07:00
