Description Agostino Sarubbo gentoo-dev 2017-06-01 08:15:55 UTC
From ${URL} :

Quick Emulator built with the USB OHCI Emulation support is vulnerable to an
infinite loop issue. It could occur while processing an endpoint list
descriptor in ohci_service_ed_list().

A guest user/process could use this flaw to crash Qemu process resulting in DoS.

Upstream patch:


@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
Comment 1 Matthias Maier gentoo-dev 2017-06-03 15:08:39 UTC
The fix is in upstream commit


which was already applied to the 2.9.0 release.

Security, please add to existing GLSA (bug #616874 and others).
