CVE-2024-12087 is a medium-severity flaw (CVSS 6.5) affecting rsync, almalinux, arch linux. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
A path traversal vulnerability exists in rsync. It stems from behavior enabled by the `--inc-recursive` option, a default-enabled option for many client options and can be enabled by the server even if not explicitly enabled by the client. When using the `--inc-recursive` option, a lack of proper symlink verification coupled with deduplication checks occurring on a per-file-list basis could allow a server to write files outside of the client's in
Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.
