Slackware Linux Advisory: rsync

Dec 04, 2003, 20:58 (0 Talkback[s])

[slackware-security] rsync security update (SSA:2003-337-01)

Rsync is a file transfer client and server.

A security problem which may lead to unauthorized machine access or code execution has been fixed by upgrading to rsync-2.5.7. This problem only affects machines running rsync in daemon mode, and is easier to exploit if the non-default option "use chroot = no" is used in the /etc/rsyncd.conf config file.

Any sites running an rsync server should upgrade immediately.

For complete information, see the rsync home page:

http://rsync.samba.org
