CentOS Linux 7 [TuxCare] Security Update: rsync (CENTOS7:CLSA-2026:1792143084)

medium Nessus Plugin ID 369492

Language:

Synopsis

The CentOS Linux host is missing one or more security updates.

Description

The CentOS Linux 7 host has a package installed that is affected by a vulnerability as referenced in the TuxCare CENTOS7:CLSA-2026:1792143084 advisory.

 - rsync before 3.5.0 contains a path traversal vulnerability that allows a malicious sender to write files outside the intended destination directory tree by crafting relative paths with symlink components in
 --relative mode. The make_path() function follows symlinks pointing outside the destination tree while creating intermediate directories without verifying that created paths remain within the destination boundary, enabling arbitrary file writes on the receiver's filesystem. (CVE-2026-53785)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected rsync package based on the guidance in TuxCare advisory CENTOS7:CLSA-2026:1792143084.
