| Description: | Description:
The remote host is missing an update to linux
announced via advisory USN-1090-1.
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. (Ubuntu 10.10 was already fixed in a prior update.) (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:

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.
