Subject: Linux 2.4.29-ow1; Owl moves to GCC 3.4.3, glibc 2.3.3+


Linux 2.4.29-ow1 is out.  Linux 2.4.29, and thus 2.4.29-ow1, adds a
number of security fixes, including to the x86/SMP page fault handler
(CAN-2005-0001) and the uselib(2) (CAN-2004-1235) race conditions,
both discovered by Paul Starzetz.  The potential of these bugs is a
local root compromise.  The uselib(2) bug does not affect default
builds of Linux kernels with the Openwall patch applied since the
vulnerable code is only compiled in if one explicitly enables
CONFIG_BINFMT_ELF_AOUT, an option introduced by the patch.  The
updated patch is available at the usual location:

Openwall GNU/*/Linux (Owl) 1.1-stable and -current branches have
already been updated to Linux 2.4.29-ow1.

Additionally, the new Owl-current snapshot uses GCC 3.4.3 and a
post-2.3.3 glibc.  Further updates will follow.  The Owl homepage is:

The FTP mirrors are listed at:

The new snapshot is not yet available on all FTP mirrors, but it
should propagate to most within 24 hours.
