Description Agostino Sarubbo gentoo-dev 2017-10-09 09:06:14 UTC
From ${URL} :

Quick Emulator(Qemu) built with the VirtFS, host directory sharing via Plan 9
File System(9pfs) support, is vulnerable to an information disclosure issue.
It could occur while accessing extended attributes of a file due to a race
condition.

A user inside guest could use this flaw to disclose uninitialised heap
memory contents on the host.

Upstream patch:
