Ubuntu Security Notice 2679-1 - A flaw was discovered in the user space memory copying for the pipe iovecs in the Linux kernel. An unprivileged local user could exploit this flaw to cause a denial of service (system crash) or potentially escalate their privileges. Daniel Borkmann reported a kernel crash in the Linux kernel's BPF filter JIT optimization. A local attacker could exploit this flaw to cause a denial of service (system crash). Various other issues were also addressed.

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 flaw was discovered in the user space memory copying for the pipe iovecs
in the Linux kernel. An unprivileged local user could exploit this flaw to
cause a denial of service (system crash) or potentially escalate their
privileges. (CVE-2015-1805)

Daniel Borkmann reported a kernel crash in the Linux kernel's BPF filter
JIT optimization. A local attacker could exploit this flaw to cause a
denial of service (system crash). (CVE-2015-4700)

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.2.0-1468-omap4 3.2.0-1468.89

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.
