The remote rsync server might be vulnerable to a path traversal issue.

An attacker may use this flaw to gain access to arbitrary files hosted outside of a module directory.

The remote host is missing Security Update 2004-09-07.  This security update fixes the following components :

  - CoreFoundation
  - IPSec
  - Kerberos
  - libpcap
  - lukemftpd
  - NetworkConfig
  - OpenLDAP
  - OpenSSH
  - PPPDialer
  - rsync
  - Safari
  - tcpdump

These applications contain multiple vulnerabilities that may allow a remote attacker to execute arbitrary code.

The remote host is affected by the vulnerability described in GLSA-200407-10 (rsync: Directory traversal in rsync daemon)

    When rsyncd is used without chroot ('use chroot = false' in the rsyncd.conf     file), the paths sent by the client are not checked thoroughly enough. If     rsyncd is used with read-write permissions ('read only = false'), this     vulnerability can be used to write files anywhere with the rights of the     rsyncd daemon. With default Gentoo installations, rsyncd runs in a chroot,     without write permissions and with the rights of the 'nobody' user.
  Impact :

    On affected configurations and if the rsync daemon runs under a privileged     user, a remote client can exploit this vulnerability to completely     compromise the host.
  Workaround :

    You should never set the rsync daemon to run with 'use chroot = false'. If     for some reason you have to run rsyncd without a chroot, then you should     not set 'read only = false'.

When running rsync in daemon mode, no checks were made to prevent clients from writing outside of a module's `path' setting.

Rsync before 2.6.1 does not properly sanitize paths when running a read/write daemon without using chroot. This could allow a remote attacker to write files outside of the module's 'path', depending on the privileges assigned to the rsync daemon. Users not running an rsync daemon, running a read-only daemon, or running a chrooted daemon are not affected by this issue. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0426 to this issue.

Updated packages were made available in June 2004 however the original update notification email did not make it to fedora-announce-list at that time.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

A vulnerability was discovered in rsync, a file transfer program, whereby a remote user could cause an rsync daemon to write files outside of the intended directory tree. This vulnerability is not exploitable when the daemon is configured with the 'chroot' option.

New rsync packages are available for Slackware 8.1, 9.0, 9.1, and
-current to fix a security issue. When running an rsync server without the chroot option it is possible for an attacker to write outside of the allowed directory. Any sites running rsync in that mode should upgrade right away (and should probably look into using the chroot option as well).

An updated rsync package that fixes a directory traversal security flaw is now available.

Rsync is a program for synchronizing files over a network.

Rsync before 2.6.1 does not properly sanitize paths when running a read/write daemon without using chroot. This could allow a remote attacker to write files outside of the module's 'path', depending on the privileges assigned to the rsync daemon. Users not running an rsync daemon, running a read-only daemon, or running a chrooted daemon are not affected by this issue. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0426 to this issue.

Users of Rsync are advised to upgrade to this updated package, which contains a backported patch and is not affected by this issue.

Rsync before 2.6.1 does not properly sanitize paths when running a read/write daemon without using chroot, allows remote attackers to write files outside of the module's path.

The updated packages provide a patched rsync to correct this problem.

 An attacker may use this flaw to create arbitrary files hosted outside of a module directory.
