Package: kernel
Summary: Several security and bug fixes.

EnGarde Secure Linux is an enterprise class Linux platform engineered to enable corporations to quickly and cost-effectively build a complete and secure Internet presence while preventing Internet threats.


This update includes Serial ATA (SATA) support, updated netfilter GRE and PPTP conntrack/NAT helpers, and a new 'forcedeth' Ethernet driver for nForce2 Ethernet support.

This update also fixes the following security issues:

  • A buffer overflow in the ISO9660 filesystem (CAN-2004-0109)
  • Information leaks in the XFS, ext3, and JFS filesystems (CAN-2004-0133, CAN-2004-0177, and CAN-2004-0181 respectively)
  • A mostly likely non-exploitable bug in the panic() function (CAN-2004-0394)
  • A potential memory leak in the do_fork() function's error path
  • An integer overflow in the ip_setsockopt() function (CAN-2004-0424)

Guardian Digital products affected by this issue include:

EnGarde Secure Community 2
EnGarde Secure Professional v1.5

It is recommended that all users apply this update as soon as possible.
