RLSA-2026:26332

Synopsis

Important: rsync security, bug fix, and enhancement update

Description

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)

Bug Fix(es) and Enhancement(s):

* Rebase rsync to version 3.4.4 in Rocky Linux10 (JIRA:Rocky Linux-181630)
