Name of the Vulnerable Software and Affected Versions rclone versions 1.75.0 through 1.75.1

Description An integer overflow exists in the multipart reorder-memory accounting of the S3 server implementation. This issue allows the configured buffer limit to be bypassed. An attacker can trigger this by opening two concurrent current-part PUT requests with excessively large lengths, causing the signed int64 counter to wrap. This results in out-of-order parts being retained in memory, which can lead to host resource exhaustion.

Recommendations Update rclone to version 1.75.2 or later.
