Fedora 43 Rsync Critical Denial of Service Vulnerability 2026-a04e445b3f

fedora
Calendar Grey June 25, 2026
Dist Fedora Esm H88
This advisory covers critical updates for rsync in Fedora 43 addressing multiple security issues.
New version 3.4.4 with multiple regression fixes

Summary

Rsync uses a reliable algorithm to bring remote and host files into

sync very quickly. Rsync is fast because it just sends the differences

in the files over the network instead of sending the complete

files. Rsync is often used as a very powerful mirroring process or

just as a more capable replacement for the rcp command. A technical

report which describes the rsync algorithm is included in this

package.

Update Information:

New version 3.4.4 with multiple regression fixes. This update also fixes the following CVEs: CVE-2026-29518 CVE-2026-43617 CVE-2026-43618 CVE-2026-43619 CVE-2026-43620 CVE-2026-45232
