Slackware 9.0 and -current. These provide an improved version of the
ptrace fix that had been applied to 2.4.20 in Slackware 9.0 (for example,
command line options now appear correctly when root does 'ps ax'), and
fix a potential denial of service problem with netfilter.

Here are the details from the Slackware 9.0 ChangeLog:
+--------------------------+
Tue Jun 17 19:41:55 PDT 2003
New precompiled Linux 2.4.21 kernels and source packages are now available
 for Slackware 9.0. These fix a few problems with the ptrace patch used
 with the 2.4.20 kernel, and add a few extra drivers (like Silicon Image
 Serial-ATA support). The new kernel also fixes a number of security
 issues, such as a routing cache problem in 2.4.20 and earlier can allow
 an attacker to cause hash collisions in the prerouting chain that consume
 CPU resources resulting in a denial-of-service (CAN-2003-0244).
patches/packages/kernel-headers-2.4.21-i386-1.tgz: Upgraded to Linux
 2.4.21 kernel headers.
patches/packages/kernel-ide-2.4.21-i486-1.tgz: Upgraded to Linux 2.4.21.
patches/packages/kernel-modules-2.4.21-i486-1.tgz: Upgraded kernel modules
 to Linux 2.4.21.
patches/packages/kernel-modules-2.4.21_xfs-i486-1.tgz: Upgraded the
 XFS-patched kernel modules package to Linux 2.4.21-xfs. These are needed
 for the xfs.i kernel.
patches/packages/kernel-source-2.4.21-noarch-1.tgz: Upgraded to Linux
 2.4.21 source.
patches/kernels/*: Upgraded to Linux 2.4.21.
(* Security fix *)
