Ubuntu Security Notice USN-2335-1
September 02, 2014

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:

An flaw was discovered in the Linux kernel's audit subsystem when auditing
certain syscalls. A local attacker could exploit this flaw to obtain
potentially sensitive single-bit values from kernel memory or cause a
denial of service (OOPS). (CVE-2014-3917)

An information leak was discovered in the rd_mcp backend of the iSCSI
target subsystem in the Linux kernel. A local user could exploit this flaw
to obtain sensitive information from ramdisk_mcp memory by leveraging
access to a SCSI initiator. (CVE-2014-4027)

Sasha Levin reported an issue with the Linux kernel's shared memory
subsystem when used with range notifications and hole punching. A local
user could exploit this flaw to cause a denial of service. (CVE-2014-4171)

An information leak was discovered in the control implemenation of the
Advanced Linux Sound Architecture (ALSA) subsystem in the Linux kernel. A
local user could exploit this flaw to obtain sensitive information from
kernel memory. (CVE-2014-4652)

A use-after-free flaw was discovered in the Advanced Linux Sound
Architecture (ALSA) control implementation of the Linux kernel. A local
user could exploit this flaw to cause a denial of service (system crash).
(CVE-2014-4653)

A authorization bug was discovered with the snd_ctl_elem_add function of
the Advanced Linux Sound Architecture (ALSA) in the Linux kernel. A local
user could exploit his bug to cause a denial of service (remove kernel
controls). (CVE-2014-4654)

A flaw discovered in how the snd_ctl_elem function of the Advanced Linux
Sound Architecture (ALSA) handled a reference count. A local user could
exploit this flaw to cause a denial of service (integer overflow and limit
bypass). (CVE-2014-4655)

An integer overflow flaw was discovered in the control implementation of
the Advanced Linux Sound Architecture (ALSA). A local user could exploit
this flaw to cause a denial of service (system crash). (CVE-2014-4656)

An integer underflow flaw was discovered in the Linux kernel's handling of
the backlog value for certain SCTP packets. A remote attacker could exploit
this flaw to cause a denial of service (socket outage) via a crafted SCTP
packet. (CVE-2014-4667)

Jason Gunthorpe reported a flaw with SCTP authentication in the Linux
kernel. A remote attacker could exploit this flaw to cause a denial of
service (NULL pointer dereference and OOPS). (CVE-2014-5077)

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.2.0-1452-omap4 3.2.0-1452.72

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.

this flaw to cause a denial of service (system crash). (CVE-2014-4656)

An integer underflow flaw was discovered in the Linux kernel's handling of
the backlog value for certain SCTP packets. A remote attacker could exploit
this flaw to cause a denial of service (socket outage) via a crafted SCTP
packet. (CVE-2014-4667)

Jason Gunthorpe reported a flaw with SCTP authentication in the Linux
kernel. A remote attacker could exploit this flaw to cause a denial of
service (NULL pointer dereference and OOPS). (CVE-2014-5077)

Update instructions:

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

Ubuntu 10.04 LTS:
linux-image-2.6.32-65-386 2.6.32-65.131
linux-image-2.6.32-65-generic 2.6.32-65.131
linux-image-2.6.32-65-generic-pae 2.6.32-65.131
linux-image-2.6.32-65-ia64 2.6.32-65.131
linux-image-2.6.32-65-lpia 2.6.32-65.131
linux-image-2.6.32-65-powerpc 2.6.32-65.131
linux-image-2.6.32-65-powerpc-smp 2.6.32-65.131
linux-image-2.6.32-65-powerpc64-smp 2.6.32-65.131
linux-image-2.6.32-65-preempt 2.6.32-65.131
linux-image-2.6.32-65-server 2.6.32-65.131
linux-image-2.6.32-65-sparc64 2.6.32-65.131
linux-image-2.6.32-65-sparc64-smp 2.6.32-65.131
linux-image-2.6.32-65-versatile 2.6.32-65.131
linux-image-2.6.32-65-virtual 2.6.32-65.131

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.
