| EnGarde Secure Linux Security Advisory March 7, 2003 |
| http://www.engardelinux.org/ ESA-20030307-007 |
| |
| Package: snort |
| Summary: RPC preprocessor buffer overflow. |

  EnGarde Secure Linux is a secure distribution of Linux that features   improved access control, host and network intrusion detection, Web   based secure remote management, e-commerce, and integrated open source   security tools.

- --------
  Recently ISS X-Force discovered a buffer overflow vulnerability in the   RPC preprocessor of the snort IDS system. A remote attacker could send   fragmented RPC records and cause snort to execute arbitrary code as the   snort user.

  To fix this vulnerability we have upgraded snort to the latest stable   version (1.9.1). All users are recommended to upgrade as soon as   possible.

  The Common Vulnerabilities and Exposures project (cve.mitre.org) has   assigned the name CAN-2003-0033 to this issue.

- --------
  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:

  1. be booted into a "standard" kernel; or
  2. 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

UPDATED PACKAGES - ----------------
  These updated packages are for EnGarde Secure Linux Community   Edition.
