NVD Description

Note: Versions mentioned in the description apply only to the upstream rclone package and not the rclone package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

rclone serve s3 versions 1.75.0 before 1.75.2 contain an integer overflow vulnerability in multipart reorder-memory accounting that bypasses the configured buffer limit. Attackers can open two concurrent current-part PUT requests declaring huge lengths to wrap the signed int64 counter and retain out-of-order parts in memory, exhausting the host.
