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.

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.");
