Summary
Important: rsync security update
Details

The rsync utility enables the users to copy and synchronize files locally or across a network. Synchronization with rsync is fast because rsync only sends the differences in files over the network instead of sending whole files. The rsync utility is also used as a mirroring tool.

Security Fix(es):

  • rsync: rsync: Remote memory disclosure via integer overflow in compressed-token decoding (CVE-2026-43618)
  • rsync: TOCTOU symlink race condition allowing local privilege escalation in daemon mode without chroot. (CVE-2026-29518)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
