linux-ti-omap4 vulnerabilities
==========================
==========================
========================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
Summary:
Several security issues were fixed in the kernel.
Software Description:
- linux-ti-omap4: Linux kernel for OMAP4
Details:
A race condition between chown() and execve() was discovered in the Linux=
kernel. A local attacker could exploit this race by using chown on a
setuid-user-binary to gain administrative privileges. (CVE-2015-3339)
Vincent Tondellier discovered an integer overflow in the Linux kernel's
netfilter connection tracking accounting of loaded extensions. An attacke=
r
on the local area network (LAN) could potential exploit this flaw to caus=
e
a denial of service (system crash of targeted system). (CVE-2014-9715)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 12.04 LTS:
linux-image-3.2.0-1464-omap4 3.2.0-1464.84
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.
