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: --------------- -> https://lists.gnu.org/archive/html/qemu-devel/2017-10/msg00729.html Reference: ---------- -> http://www.openwall.com/lists/oss-security/2017/10/06/1 @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.
