Kerentanan Improper Link Resolution Before File Access ('Link Following') pada samba rsync. Skor CVSS 3.1 4.7 (Medium) menurut vulncheck.com.

Deskripsi (NVD)

rsync before 3.5.0 contains a symlink race condition vulnerability in the --remove-source-files feature that allows attackers with symlink creation access to cause arbitrary file deletion. Attackers can atomically substitute a symlink for a source file between transfer completion and the unlink() call, causing rsync to delete the symlink target rather than the intended source file.
