Summary

Several security issues were fixed in QEMU.

Software description

  • qemu
    – Machine emulator and virtualizer

  • qemu-kvm

Details

Matt Tait discovered that QEMU incorrectly handled the virtual PCNET
driver. A malicious guest could use this issue to cause a denial of
service, or possibly execute arbitrary code on the host as the user running
the QEMU process. In the default installation, when QEMU is used with
libvirt, attackers would be isolated by the libvirt AppArmor profile.

Kurt Seifried discovered that QEMU incorrectly handled certain temporary
files. A local attacker could use this issue to cause a denial of service.
(CVE-2015-4037)

Jan Beulich discovered that the QEMU Xen code incorrectly restricted write
access to the host MSI message data field. A malicious guest could use this
issue to cause a denial of service. This issue only applied to Ubuntu 14.04
LTS, Ubuntu 14.10 and Ubuntu 15.04. (CVE-2015-4103)

Jan Beulich discovered that the QEMU Xen code incorrectly restricted access
to the PCI MSI mask bits. A malicious guest could use this issue to cause a
denial of service. This issue only applied to Ubuntu 14.04 LTS, Ubuntu
14.10 and Ubuntu 15.04. (CVE-2015-4104)

Jan Beulich discovered that the QEMU Xen code incorrectly handled MSI-X
error messages. A malicious guest could use this issue to cause a denial of
service. This issue only applied to Ubuntu 14.04 LTS, Ubuntu 14.10 and
Ubuntu 15.04. (CVE-2015-4105)

Jan Beulich discovered that the QEMU Xen code incorrectly restricted write
access to the PCI config space. A malicious guest could use this issue to
cause a denial of service, obtain sensitive information, or possibly
execute arbitrary code. This issue only applied to Ubuntu 14.04 LTS,
Ubuntu 14.10 and Ubuntu 15.04. (CVE-2015-4106)

USN-2631-1: Linux kernel vulnerabilities

Ubuntu Security Notice USN-2631-1

10th June, 2015

linux 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
    – Linux kernel

Details

Jan Beulich discovered the Xen virtual machine subsystem of the Linux
kernel did not properly restrict access to PCI command registers. A local
guest user could exploit this flaw to cause a denial of service (host
crash). (CVE-2015-2150)

A privilege escalation was discovered in the fork syscall via the int80
entry on 64 bit kernels with 32 bit emulation support. An unprivileged
local attacker could exploit this flaw to increase their privileges on the
system. (CVE-2015-2830)

A memory corruption issue was discovered in AES decryption when using the
Intel AES-NI accelerated code path. A remote attacker could exploit this
flaw to cause a denial of service (system crash) or potentially escalate
privileges on Intel base machines with AEC-GCM mode IPSec security
association. (CVE-2015-3331)

Wen Xu discovered a use-after-free flaw in the Linux kernel’s ipv4 ping
support. A local user could exploit this flaw to cause a denial of service
(system crash) or gain administrative privileges on the system.
(CVE-2015-3636)

Carl H Lunde discovered missing sanity checks in the the Linux kernel’s UDF
file system(CONFIG_UDF_FS). A local attack could exploit this flaw to cause
a denial of service (system crash) by using a corrupted filesystem image.
(CVE-2015-4167)

Update instructions

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

Ubuntu 12.04 LTS:
linux-image-3.2.0-85-virtual

3.2.0-85.122
linux-image-3.2.0-85-generic-pae

3.2.0-85.122
linux-image-3.2.0-85-powerpc-smp

3.2.0-85.122

3.2.0-85.122
linux-image-3.2.0-85-omap

3.2.0-85.122
linux-image-3.2.0-85-generic

3.2.0-85.122
linux-image-3.2.0-85-highbank

3.2.0-85.122

To update your system, please follow these instructions:
https://wiki.ubuntu.com/Security/Upgrades.

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.
