Upstream addressed it by replacing the program's path handling wholesale in a later release and re-pointing every call site at it; importing that would rewrite every file-creation path in the sending and receiving code, the highest-risk area of the program. The flaw needs an attacker who can plant a symlink at one of the paths an operator names — a filter file, a file list, or the password or secrets file. The program then reads an arbitrary file as filter rules, or sends a victim file's contents as its authentication response. To stay safe, keep file lists, password files, filter files and the daemon secrets file inside root-owned directories, and refuse the files-from, include-from, exclude-from and filter options on modules that do not need them.", "product_ids": [ "Debian-10:rsync-0:3.1.3-6+tuxcare.els1.amd64", "Debian-10:rsync-0:3.1.3-6+tuxcare.els2.amd64", "Debian-10:rsync-0:3.1.3-6+tuxcare.els3.amd64", "Debian-10:rsync-0:3.1.3-6+tuxcare.els4.amd64", "Debian-10:rsync-0:3.1.3-6.amd64" ] } ] } ] }
