It can copy locally, to/from another host over any remote shell, or to/from a remote rsync daemon. It offers a large number of options that control every aspect of its behavior and permit very flexible specification of the set of files to be copied. It is famous for its delta-transfer algorithm, which reduces the amount of data sent over the network by sending only the differences between the source files and the existing files in the destination. Rsync is widely used for backups and mirroring and as an improved copy command for everyday use. %prep -%autosetup +%autosetup -p1 %build %configure --with-included-zlib=no --disable-xxhash @@ -60,6 +61,9 @@ EOF %{_sysconfdir}/rsyncd.conf %changelog +* Mon Sep 07 2026 Azure Linux Security Servicing Account - 3.5.0-2 +- Patch for CVE-2026-18743 + * Fri Aug 14 2026 CBL-Mariner Servicing Account - 3.5.0-1 - Auto-upgrade to 3.5.0 - for CVE-2026-70458, CVE-2026-53789, CVE-2026-70461, CVE-2026-53800, CVE-2026-53803, CVE-2026-53795, CVE-2026-70454, CVE-2026-53797, CVE-2026-53791, CVE-2026-53792, CVE-2026-53801, CVE-2026-70464, CVE-2026-70452, CVE-2026-53793, CVE-2026-70463, CVE-2026-53798, CVE-2026-70455, CVE-2026-53802, CVE-2026-53785, CVE-2026-53796, CVE-2026-53788, CVE-2026-53786, CVE-2026-53783, CVE-2026-70460, CVE-2026-70459, CVE-2026-53790, CVE-2026-53794, CVE-2026-70462, CVE-2026-70456, CVE-2026-70457, CVE-2026-53799, CVE-2026-53784, CVE-2026-70453, CVE-2026-18839, CVE-2026-18739, CVE-2026-41035
