Patched kernels and kernel packages for Linux 2.6.29.6 to address
a bug in proto_ops structures which could allow a user to use the
kernel sendpage operation to execute arbitrary code in page zero.
This could allow local users to gain escalated privileges.
This flaw was discovered by Tavis Ormandy and Julien Tinnes of the
Google Security Team.
For more information, see:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-2692
In addition, these kernels change the CONFIG_DEFAULT_MMAP_MIN_ADDR
kernel config option value to 4096, which should prevent the execution
of arbitrary code by future NULL dereference bugs that might be found
in the kernel. If you are compiling your own kernel, please check this
option in your .config. If it is set to =0, you may wish to edit it
to 4096 (or some other value > 0) and then reconfigure, or the kernel
will not have default protection against zero page attacks from
userspace.

a/aaa_elflibs-13.0-x86_64-1.txz: Upgraded.
a/mkinitrd-1.3.4-x86_64-3.txz: Rebuilt. Fixed quoting of "${MODULE_LIST}"
a/usbutils-0.82-x86_64-2.txz: Rebuilt. Updated usb.ids, removed usb.ids.gz.
ap/man-pages-3.22-noarch-2.txz: Rebuilt. Fixed missing part of doinst.sh.
kde/koffice-2.0.2-x86_64-1.txz: Upgraded.
kdei/koffice-l10n-*-2.0.2-noarch-1.txz:
Upgraded to KOffice 2.0.2 l10n packages.
l/jre-6u16-x86_64-1.txz: Upgraded.
Upgraded to Java(TM) 2 Platform Standard Edition Runtime Environment
Version 6.0 update 16.
n/curl-7.19.6-x86_64-1.txz: Upgraded.
This update fixes a security issue where a zero byte embedded in an SSL
or TLS certificate could fool cURL into validating the security of a
connection to a system that the certificate was not issued for. It has
been reported that at least one Certificate Authority allowed such
certificates to be issued.

(* Security fix *)
n/elm-2.5.8-x86_64-3.txz: Rebuilt. Fixed mailermode.
t/transfig-3.2.4-x86_64-2.txz: Reverted. This version is matched to
xfig-3.2.4.
t/xfig-3.2.4-x86_64-4.txz: Reverted. This is due to xfig-3.2.5b not working
correctly. .fig files will load, but making any changes causes xfig to
hang consuming 100% CPU. We couldn't find a fix, and honestly RC2 just
wasn't a good time to upgrade xfig (3.2.4 also required many patches to
work right). Sorry, but we'll look at this again in the next -current.
extra/aspell-word-lists/aspell-nb-0.50.1_0-noarch-4.txz: Added.
extra/jdk-6/jdk-6u16-x86_64-1.txz: Upgraded.
Upgraded to Java(TM) 2 Platform Standard Edition Development Kit
Version 6.0 update 16.
extra/wicd/wicd-1.6.2-x86_64-2.txz: Rebuilt.
Fixed a problem with hidden networks. Thanks to Robby Workman.
isolinux/initrd.img: Rebuilt.
