Descriptions
QEMU does not properly restrict write access to the PCI config space for certain PCI pass-through devices, which might allow local x86 HVM guests to gain privileges, cause a denial of service (host crash), obtain sensitive information, or possibly have other unspecified impact via unknown vectors.
QEMU no restringe correctamente el acceso a escritura al espacio PCI config para ciertos dispositivos PCI pass-through, lo que podría permitir a invitados x86 HVM locales obtener privilegios, causar una denegación de servicio (caída de host), obtener información sensible o posiblemente tener otro impacto no especificado a través de vectores desconocidos.
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. Various other issues were also addressed.
