  script_tag(name:"insight", value:"New Linux kernel packages are available for Slackware 12.2 and -current
to address a security issue.  A kernel bug discovered by Tavis Ormandy
and Julien Tinnes of the Google Security Team could allow a local user
to fill memory page zero with arbitrary code and then use the kernel
sendpage operation to trigger a NULL pointer dereference, executing the
code in the context of the kernel.  If successfully exploited, this bug
can be used to gain root access.

At this time we have prepared fixed kernels for the stable version of
Slackware (12.2), as well as for both 32-bit x86 and x86_64 -current
versions.  Additionally, we have added a package to the /patches
directory for Slackware 12.1 and 12.2 that will set the minimum memory
page that can be mmap()ed from userspace without additional privileges
to 4096.  The package will work with any kernel supporting the
vm.mmap_min_addr tunable, and should significantly reduce the potential
harm from this bug, as well as future similar bugs that might be found
in the kernel.  More updated kernels may follow.");
