========================================================================== Ubuntu Security Notice USN-3414-2 September 20, 2017
qemu regression ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 17.04 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS
Summary:
USN-3414-1 introduced a regression in QEMU.
Software Description: - qemu: Machine emulator and virtualizer
Details:
USN-3414-1 fixed vulnerabilities in QEMU. The patch backport for CVE-2017-9375 was incomplete and caused a regression in the USB xHCI controller emulation support. This update fixes the problem.
We apologize for the inconvenience.
