Description Prasad Pandit 2017-10-06 05:26:11 UTC 
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.
