High Nessus Plugin ID 102805

Description

Multiple vulnerabilities were discovered in qemu-kvm, a full virtualization solution for Linux hosts on x86 hardware with x86 guests based on the Quick Emulator(Qemu).

Denial of service via infinite loop in the USB OHCI emulation

We recommend that you upgrade your qemu-kvm 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.

Solution

Upgrade the affected kvm, qemu-kvm, and qemu-kvm-dbg packages.
