Debian DLA-678-1 : qemu security update

Low Nessus Plugin ID 94257

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 5.2


The remote Debian host is missing a security update.


Multiple vulnerabilities have been found in QEMU :


Quick Emulator (Qemu) built with the USB xHCI controller emulation support is vulnerable to an infinite loop issue. It could occur while processing USB command ring in 'xhci_ring_fetch'.


Quick Emulator (Qemu) built with the virtio-9p back-end support is vulnerable to a memory leakage issue. It could occur while doing a I/O read operation in v9fs_read() routine.


Quick Emulator (Qemu) built with the virtio-9p back-end support is vulnerable to a NULL pointer dereference issue. It could occur while doing an I/O vector unmarshalling operation in v9fs_iov_vunmarshal() routine.


Quick Emulator (Qemu) built with the 16550A UART emulation support is vulnerable to a divide by zero issue. It could occur while updating serial device parameters in 'serial_update_parameters'.

For Debian 7 'Wheezy', these problems have been fixed in version 1.1.2+dfsg-6+deb7u17.

We recommend that you upgrade your qemu packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Upgrade the affected packages.
