| EnGarde Secure Linux Security Advisory July 02, 2002 |

| Package: openssh |
| Summary: several vulnerabilities in the OpenSSH daemon. |
+------------------------------------------------------------------------+
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
- --------
ISS and the OpenBSD team found several vulnerabilities in the OpenSSH
secure shell daemon as outlined by the OpenSSH advisory [1] and the ISS
advisory [2]. Guardian Digital issued ESA-20020625-015 on June 25,
2002, upgrading all users to version 3.3p1 which introduced privilege
separation (and mitigates some of the risk introduced by these
vulnerabilities).
This update brings the current version up to 3.4p1 and properly fixes
the known bugs, along with a potential class of new bugs (as mentioned
in the OpenSSH advisory).

SOLUTION
- --------
Users of the EnGarde Professional edition can use the Guardian Digital
Secure Network to update their systems automatically.
EnGarde Community users should upgrade to the most recent version
as outlined in this advisory. Updates may 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 files
You must now update the LIDS configuration by executing the command:
# /usr/sbin/config_lids.pl
To re-enable LIDS (if it was disabled), execute the command:
# /sbin/lidsadm -S -- +LIDS_GLOBAL
To verify the signatures of the updated packages, execute the command:
# rpm -Kv files
