Ubuntu Security Notice USN-1404-1
March 27, 2012
linux-ti-omap4 vulnerability
==========================
==========================
========================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.10
Summary:
The system could be made to deny services if it received specially crafte=
d
local area network traffic.
Software Description:
- linux-ti-omap4: Linux kernel for OMAP4
Details:
Somnath Kotur discovered an error in the Linux kernel's VLAN (virtual lan=
)
and be2net drivers. An attacker on the local network could exploit this
flaw to cause a denial of service.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 11.10:
linux-image-3.0.0-1208-omap4 3.0.0-1208.18
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 automaticall=
y
perform this as well.
