| Package: xinetd |
| Summary: Several potential vulnerabilities |
+------------------------------------------------------------------------+
EnGarde Secure Linux is a secure distribution of Linux that features
improved access control, host and network intrusion detection, Web
based secure remote management, complete e-commerce using AllCommerce,
and integrated open source security tools.
OVERVIEW
- --------
There are some potential vulnerabilities in the most recent xinetd
package for EnGarde Secure Linux 1.0.1.
DETAIL
- ------
Solar Designer did an audit of xinetd 2.3.0 and came up with a list
of potential vulnerabilities. This release fixes all known
vulnerabilities as a precautionary measure. Most of these fixes are
in the interest of robustness and are not known to be exploitable at
this time.
For more information on the results of this audit please refer to
the AUDIT file in the xinetd-2.3.3.tar.gz tarball (included with
the source package).
SOLUTION
- --------
All users should upgrade to the most recent version, as outlined in
this advisory.
Guardian Digital recently made available the Guardian Digital Secure
Update, a means to proactively keep systems secure and manage
system software. EnGarde users can automatically update their system
using the Guardian Digital WebTool secure interface.
If choosing to manually upgrade this package, updates can be
obtained from:
ftp://ftp.engardelinux.org/pub/engarde/stable/updates/http://ftp.engardelinux.org/pub/engarde/stable/updates/
Before upgrading the package, the machine must either:
a) be booted into a "standard" kernel; or
b) have LIDS disabled.
To disable LIDS, execute the command:
# /sbin/lidsadm -S -- -LIDS_GLOBAL
To install the updated package, execute the command:
# rpm -Uvh <filename>
To re-enable LIDS (if it was disabled), execute the command:
# /sbin/lidsadm -S -- +LIDS_GLOBAL
To verify the signature of the updated packages, execute the command:
# rpm -Kv <filename>
