QID 670926: EulerOS Security Update for rsync (EulerOS-SA-2021-1844)

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. Security Fix(es): rsync 3.1.1 allows remote attackers to write to arbitrary files via a symlink attack on a file in the synchronization path.(CVE-2014-9512)
