Hash: SHA1

| Guardian Digital Security Advisory May 15, 2003 |
| ESA-20030515-017 |
| |
| Package: kernel |
| Summary: several bug and security-related 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 kernel update fixes several bugs and vulnerabilities. A summary
of the changes from the last kernel update are below.

* Systems with more then one swap partition defined could OOPS when
"swapoff -a" was run.

* This update improves the kernel module loader vulnerability fix
(CAN-2003-0127) initially fixed in ESA-20030318-009.

* Using specially selected forged source addresses, a remote attacker
can cause a very large number of collisions in the kernel's
networking hash tables, resulting in a denial of service attack.

The Common Vulnerabilities and Exposures project ( has
assigned the name CAN-2003-0244 to this issue.

* The "ioperm" system call does not properly restrict privileges,
potentially allowing an unprivileged local user access to the I/O
ports on the system.

The Common Vulnerabilities and Exposures project ( has
assigned the name CAN-2003-0246 to this issue.

Guardian Digital products affected by these issues include:

EnGarde Secure Community 2
EnGarde Secure Professional v1.5

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