Echo: rsync: security update to 3.5.0

high Tenable Cloud Security Plugin ID 458226

Description

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

 - rsync 3.2.3 before 3.5.0 contains an out-of-bounds write in parse_size_arg() where the return value of
 snprintf() is used directly as an index into a .bss-segment array without bounds checking. When snprintf
 truncates the formatted size string, the return value equals the number of characters that would have been
 written including the truncated portion, and this value may exceed the array length. The subsequent
 indexed write targets memory outside the intended array bounds, corrupting .bss memory. (CVE-2026-70457)

Solution

Update the rsync library and its related packages to version 3.5.0 or later.
