Trustix Secure Linux Security Advisory #2001-0028

Package name:      kernel
Severity:          local root exploit and DoS attack
Date:              2001-10-19
Affected versions: TSL 1.01, 1.1, 1.2, 1.5

- --------------------------------------------------------------------------

Problem description:
  As reported on Bugtraq, there is a local root exploit in the Linux
  kernel involving the ptrace call.  In addition, it is possible to create
  a Denial of Service attack in the kernel by creating a number of symlinks.


Action:
  We recommend that all systems with this package installed are upgraded.


Location:
  All TSL updates are available from
  <URI:http://www.trustix.net/pub/Trustix/updates/>
  <URI:ftp://ftp.trustix.net/pub/Trustix/updates/>


Automatic updates:
  Users of the SWUP tool, can enjoy having updates automatically
  installed using 'swup --upgrade'.  Note that kernel packages are not
  normally suited for automatic updates.
