Test ID:1.3.6.1.4.1.25623.1.0.69348
Category:Ubuntu Local Security Checks
Title:Ubuntu USN-1086-1 (linux-ec2)
Summary:Ubuntu USN-1086-1 (linux-ec2)
Description:The remote host is missing an update to linux-ec2
announced via advisory USN-1086-1.

Details follow:

Dan Rosenberg discovered that multiple terminal ioctls did not correctly
initialize structure memory. A local attacker could exploit this to
read portions of kernel stack memory, leading to a loss of privacy.
(CVE-2010-4076, CVE-2010-4077)

Dan Rosenberg discovered that the socket filters did not correctly
initialize structure memory. A local attacker could create malicious
filters to read portions of kernel stack memory, leading to a loss of
privacy. (CVE-2010-4158)

Dan Rosenberg discovered that the SCSI subsystem did not correctly
validate iov segments. A local attacker with access to a SCSI device
could send specially crafted requests to crash the system, leading to
a denial of service. (CVE-2010-4163)

Dan Rosenberg discovered that the RDS protocol did not correctly check
ioctl arguments. A local attacker could exploit this to crash the system,
leading to a denial of service. (CVE-2010-4175)

Solution:
The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 10.04 LTS:
linux-image-2.6.32-314-ec2 2.6.32-314.27

After a standard system update you need to reboot your computer to make
all the necessary changes.

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.
