{"id":"USN-2630-1","summary":"qemu, qemu-kvm vulnerabilities","details":"Matt Tait discovered that QEMU incorrectly handled the virtual PCNET\ndriver. A malicious guest could use this issue to cause a denial of\nservice, or possibly execute arbitrary code on the host as the user running\nthe QEMU process. In the default installation, when QEMU is used with\nlibvirt, attackers would be isolated by the libvirt AppArmor profile.\n(CVE-2015-3209)\n\nKurt Seifried discovered that QEMU incorrectly handled certain temporary\nfiles. A local attacker could use this issue to cause a denial of service.\n(CVE-2015-4037)\n\nJan Beulich discovered that the QEMU Xen code incorrectly restricted write\naccess to the host MSI message data field. A malicious guest could use this\nissue to cause a denial of service. This issue only applied to Ubuntu 14.04\nLTS, Ubuntu 14.10 and Ubuntu 15.04. (CVE-2015-4103)\n\nJan Beulich discovered that the QEMU Xen code incorrectly restricted access\nto the PCI MSI mask bits. A malicious guest could use this issue to cause a\ndenial of service. This issue only applied to Ubuntu 14.04 LTS, Ubuntu\n14.10 and Ubuntu 15.04. (CVE-2015-4104)\n\nJan Beulich discovered that the QEMU Xen code incorrectly handled MSI-X\nerror messages. A malicious guest could use this issue to cause a denial of\nservice. This issue only applied to Ubuntu 14.04 LTS, Ubuntu 14.10 and\nUbuntu 15.04. (CVE-2015-4105)\n\nJan Beulich discovered that the QEMU Xen code incorrectly restricted write\naccess to the PCI config space. A malicious guest could use this issue to\ncause a denial of service, obtain sensitive information, or possibly\nexecute arbitrary code. This issue only applied to Ubuntu 14.04 LTS,\nUbuntu 14.10 and Ubuntu 15.04.
