Echo: rclone: security update to 1.75.2-1

high Tenable Cloud Security Plugin ID 478386

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- rclone versions >= v1.72.0 and <= v1.74.4 (fixed in v1.75.0) contain multiple denial-of-service
vulnerabilities in the archive backend's SquashFS parser, which relies on the github.com/diskfs/go-diskfs
dependency. The parser fails to validate attacker-controlled superblock and metadata values before use. An
attacker who can place or modify a SquashFS image in storage exposed through an rclone :archive: remote
can craft a malicious image that triggers an integer division-by-zero panic (zero block size), an out-of-
bounds slice panic (out-of-range inode metadata offset), or a non-progress CPU loop (truncated metadata
stream). Variants 1 and 2 terminate the rclone process and, via 'rclone serve sftp', can crash the entire
SFTP server; variant 3 causes sustained CPU consumption. Parsing is lazy, so a victim or remote client
must address or descend into the malicious archive object to trigger it. (CVE-2026-79775)

Solution

Update the rclone library and its related packages to version 1.75.2-1 or later.
