EnGarde Secure Linux: OpenSSH and mod_ssl

EnGarde Secure Linux: "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. 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."

  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

+------------------------------------------------------------------------+

  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
- --------
  Frank Denis (j@pureftpd.org) discovered an off-by-one error in mod_ssl's
  handling of older configuration directives (the rewrite_command hook).
  As such a malicious user, using a specially-crafted .htaccess file, may 
  be able to DoS the child (Apache) processes or execute arbitrary
  commands as the webd user.

  This update upgrades mod_ssl to 2.8.10, fixing this problem and other
  bugs.

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:
