Description Arvid Requate

Upstream Debian [wheezy] package version 1.1.2+dfsg-6a+deb7u11 fixes these issues:

* the QEMU model of the RTL8139 network card did not sufficiently validate inputs in the C+ mode offload emulation, allowing a malicious guest to read uninitialized memory from the QEMU process's heap (CVE-2015-5165)

* A buffer overflow vulnerability was discovered in the way QEMU handles the virtio-serial device. A malicious guest could use this flaw to mount a denial of service (QEMU process crash) (CVE-2015-5745)

* infinite loop when receiving packets in the NE2000 NIC emulation. A privileged guest user could use this flaw to mount a denial of service (QEMU process crash) (CVE-2015-5278)

* heap buffer overflow flaw in the NE2000 NIC emulation. A privileged guest user could use this flaw to mount a denial of service (QEMU process crash), or potentially to execute arbitrary code on the host with the privileges of the hosting QEMU process (CVE-2015-5279)

* infinite loop issue in the e1000 NIC emulation. A privileged guest user could use this flaw to mount a denial of service (QEMU process crash) (CVE-2015-6815)

* flaw in the IDE subsystem in QEMU occurring while executing IDE's WIN_READ_NATIVE_MAX command to determine the maximum size of a drive. A privileged guest user could use this flaw to mount a denial of service (QEMU process crash) (CVE-2015-6855)

OK: source version 1.1.2+dfsg-6+deb7u11 was imported
OK: YAML
OK: installs and can be executed, but without hardware I cannot test it more than that
