===========================================================
A security issue affects the following Ubuntu releases:
Ubuntu 10.04 LTS
Ubuntu 10.10
This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.
The problem can be corrected by upgrading your system to the
following package versions:
Ubuntu 10.04 LTS:
linux-image-2.6.32-216-dove 2.6.32-216.33
Ubuntu 10.10:
linux-image-2.6.32-416-dove 2.6.32-416.33
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-generic,
linux-server, linux-powerpc), a standard system upgrade will automatically
perform this as well.
Details follow:
Joel Becker discovered that OCFS2 did not correctly validate on-disk
symlink structures. If an attacker were able to trick a user or automated
system into mounting a specially crafted filesystem, it could crash the
system or exposde kernel memory, leading to a loss of privacy.

check certain sizes. A local attacker could perform malicious ioctl calls
that could crash the system, leading to a denial of service. (Only Ubuntu
10.04 LTS was affected.) (CVE-2010-2478, CVE-2010-3084)

stack contents. A local attacker could exploit this to read portions
of kernel memory, leading to a loss of privacy. (Ubuntu 10.10 was not
affected.) (CVE-2010-2942, CVE-2010-3477)

calculations. A remote attacker could send specially crafted traffic
that would crash the system, leading to a denial of service.

driver. A local user could cause a denial of service via a NULL pointer
dereference, escalate privileges by overflowing the kernel stack, and
assign Econet addresses to arbitrary interfaces. (CVE-2010-3848,
CVE-2010-3849, CVE-2010-3850)
Brad Spengler discovered that stack memory for new a process was not
correctly calculated. A local attacker could exploit this to crash the
system, leading to a denial of service. (CVE-2010-3858)
