The remote Redhat Enterprise Linux 4 host has one or more packages installed that are affected by a vulnerability that has been acknowledged by the vendor but will not be patched.

  - rsync excluded content access restrictions bypass via symlinks (CVE-2007-6200)

Note that Nessus has not tested for this issue but has instead relied on the package manager's report that the package is installed.

This update fixes a bug in rsync that allowed remote attackers to access restricted files outside a module's hierarchy if no chroot setup was used. (CVE-2007-6199) Please read http://rsync.samba.org/security.html entry from November 28th, 2007 to get more information about a secure configuration of rsync that also covers the bug tracked with CVE-2007-6200. This update also fixes some crashes that only affect rsync-2.6.8 on SLES10.

An updated rsync package that fixes one security issue, several bugs, and adds enhancements is now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

rsync is a program for synchronizing files over a network.

A flaw was found in the way the rsync daemon handled the 'filter', 'exclude', and 'exclude from' options, used for hiding files and preventing access to them from rsync clients. A remote attacker could use this flaw to bypass those restrictions by using certain command line options and symbolic links, allowing the attacker to overwrite those files if they knew their file names and had write access to them. (CVE-2007-6200)

Note: This issue only affected users running rsync as a writable daemon: 'read only' set to 'false' in the rsync configuration file (for example, '/etc/rsyncd.conf'). By default, this option is set to 'true'.

This update also fixes the following bugs :

* The rsync package has been upgraded to upstream version 3.0.6, which provides a number of bug fixes and enhancements over the previous version. (BZ#339971)

* When running an rsync daemon that was receiving files, a deferred info, error or log message could have been sent directly to the sender instead of being handled by the 'rwrite()' function in the generator.
Also, under certain circumstances, a deferred info or error message from the receiver could have bypassed the log file and could have been sent only to the client process. As a result, an 'unexpected tag 3' fatal error could have been displayed. These problems have been fixed in this update so that an rsync daemon receiving files now works as expected. (BZ#471182)

* Prior to this update, the rsync daemon called a number of timezone-using functions after doing a chroot. As a result, certain C libraries were unable to generate proper timestamps from inside a chrooted daemon. This bug has been fixed in this update so that the rsync daemon now calls the respective timezone-using functions prior to doing a chroot, and proper timestamps are now generated as expected. (BZ#575022)

* When running rsync under a non-root user with the '-A' ('--acls') option and without using the '--numeric-ids' option, if there was an Access Control List (ACL) that included a group entry for a group that the respective user was not a member of on the receiving side, the 'acl_set_file()' function returned an invalid argument value ('EINVAL'). This was caused by rsync mistakenly mapping the group name to the Group ID 'GID_NONE' ('-1'), which failed. The bug has been fixed in this update so that no invalid argument is returned and rsync works as expected. (BZ#616093)

* When creating a sparse file that was zero blocks long, the 'rsync
--sparse' command did not properly truncate the sparse file at the end of the copy transaction. As a result, the file size was bigger than expected. This bug has been fixed in this update by properly truncating the file so that rsync now copies such files as expected.
(BZ#530866)

* Under certain circumstances, when using rsync in daemon mode, rsync generator instances could have entered an infinitive loop, trying to write an error message for the receiver to an invalid socket. This problem has been fixed in this update by adding a new sibling message:
when the receiver is reporting a socket-read error, the generator will notice this fact and avoid writing an error message down the socket, allowing it to close down gracefully when the pipe from the receiver closes. (BZ#690148)

* Prior to this update, there were missing deallocations found in the 'start_client()' function. This bug has been fixed in this update and no longer occurs. (BZ#700450)

All users of rsync are advised to upgrade to this updated package, which resolves these issues and adds enhancements.

The remote host is running a version of Mac OS X 10.5 or 10.4 that does not have the security update 2008-005 applied. 

This update contains security fixes for a number of programs.

The remote Redhat Enterprise Linux 3 host has one or more packages installed that are affected by a vulnerability that has been acknowledged by the vendor but will not be patched.

  - rsync excluded content access restrictions bypass via symlinks (CVE-2007-6200)

Note that Nessus has not tested for this issue but has instead relied on the package manager's report that the package is installed.

rsync before 3.0.0pre6, when running a writable rsync daemon that is not using chroot, allows remote attackers to access restricted files via unknown vectors that cause rsync to create a symlink that points outside of the module's hierarchy. (CVE-2007-6199)

Unspecified vulnerability in rsync before 3.0.0pre6, when running a writable rsync daemon, allows remote attackers to bypass exclude, exclude_from, and filter and read or write hidden files via (1) symlink, (2) partial-dir, (3) backup-dir, and unspecified (4) dest options. (CVE-2007-6200)

This update fixes these issues. It is recommended users (specially system and network administrators) read the manpage about the introduced munge symlinks feature.

This update also upgrades rsync to version 2.6.9 for all Mandriva Linux versions earlier than 2008.0.

The remote Redhat Enterprise Linux 5 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2011:0999 advisory.

  - rsync excluded content access restrictions bypass via symlinks (CVE-2007-6200)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote Oracle Linux 5 host has a package installed that is affected by a vulnerability as referenced in the ELSA-2011-0999 advisory.

  - Unspecified vulnerability in rsync before 3.0.0pre6, when running a writable rsync daemon, allows remote     attackers to bypass exclude, exclude_from, and filter and read or write hidden files via (1) symlink, (2)     partial-dir, (3) backup-dir, and unspecified (4) dest options.
