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.

@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.

The fix is in upstream commit

  26f670a244982335cc08943fb1ec099a2c81e42d

which was already applied to the 2.9.0 release.


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