Description:	Summary: Several vulnerabilities were discovered in qemu, a fast processor emulator. CVE-2015-3209 Matt Tait of Google's Project Zero security team discovered a flaw in the way QEMU's AMD PCnet Ethernet emulation handles multi-TMD packets with a length above 4096 bytes. A privileged guest user in a guest with an AMD PCNet ethernet card enabled can potentially use this flaw to execute arbitrary code on the host with the privileges of the hosting QEMU process. CVE-2015-4037 Kurt Seifried of Red Hat Product Security discovered that QEMU's user mode networking stack uses predictable temporary file names when the -smb option is used. An unprivileged user can use this flaw to cause a denial of service. CVE-2015-4103 Jan Beulich of SUSE discovered that the QEMU Xen code does not properly restrict write access to the host MSI message data field, allowing a malicious guest to cause a denial of service. CVE-2015-4104 Jan Beulich of SUSE discovered that the QEMU Xen code does not properly restrict access to PCI MSI mask bits, allowing a malicious guest to cause a denial of service. CVE-2015-4105 Jan Beulich of SUSE reported that the QEMU Xen code enables logging for PCI MSI-X pass-through error messages, allowing a malicious guest to cause a denial of service. CVE-2015-4106 Jan Beulich of SUSE discovered that the QEMU Xen code does not properly restrict write access to the PCI config space for certain PCI pass-through devices, allowing a malicious guest to cause a denial of service, obtain sensitive information or potentially execute arbitrary code. Affected Software/OS: qemu on Debian Linux Solution: For the oldstable distribution (wheezy), these problems have been fixed in version 1.1.2+dfsg-6a+deb7u8. Only CVE-2015-3209 and CVE-2015-4037 affect oldstable. For the stable distribution (jessie), these problems have been fixed in version 1:2.1+dfsg-12+deb8u1. For the unstable distribution (sid), these problems have been fixed in version 1:2.3+dfsg-6. We recommend that you upgrade your qemu packages. CVSS Score: 7.8 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:C
