For the stable distribution (woody) this problem has been fixed in
version 2.4.18-14.2 of kernel-source, version 2.4.18-14 of alpha
images, version 2.4.18-12.2 of i386 images, version 2.4.18-5woody7 of
i386bf images and version 2.4.18-1woody4 of powerpc images.

Other architectures will probably mentioned in a separate advisory or
are not affected (m68k).

This problem is also fixed in the upstream version of Linux 2.4.25 and
2.6.3.
