    qemu, qemu-kvm vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 14.04 LTS
    - Ubuntu 12.04 LTS
    - Ubuntu 10.04 LTS
    
    Summary:
    
    Several security issues were fixed in QEMU.
    
    Software Description:
    - qemu: Machine emulator and virtualizer
    - qemu-kvm: Machine emulator and virtualizer
    
    Details:
    
    Michael S. Tsirkin, Anthony Liguori, and Michael Roth discovered multiple
    issues with QEMU state loading after migration. An attacker able to modify
    the state data could use these issues to cause a denial of service, or
    possibly execute arbitrary code. (CVE-2013-4148, CVE-2013-4149,
    CVE-2013-4150, CVE-2013-4151, CVE-2013-4526, CVE-2013-4527, CVE-2013-4529,
    CVE-2013-4530, CVE-2013-4531, CVE-2013-4532, CVE-2013-4533, CVE-2013-4534,
    CVE-2013-4535, CVE-2013-4536, CVE-2013-4537, CVE-2013-4538, CVE-2013-4539,
    CVE-2013-4540, CVE-2013-4541, CVE-2013-4542, CVE-2013-6399, CVE-2014-0182,
    CVE-2014-3461)
    
    Kevin Wolf, Stefan Hajnoczi, Fam Zheng, Jeff Cody, Stefan Hajnoczi, and
    others discovered multiple issues in the QEMU block drivers. An attacker
    able to modify disk images could use these issues to cause a denial of
    service, or possibly execute arbitrary code. (CVE-2014-0142, CVE-2014-0143,
    CVE-2014-0144, CVE-2014-0145, CVE-2014-0146, CVE-2014-0147, CVE-2014-0222,
    CVE-2014-0223)
    
    It was discovered that QEMU incorrectly handled certain PCIe bus hotplug
    operations. A malicious guest could use this issue to crash the QEMU host,
    resulting in a denial of service. (CVE-2014-3471)
