From ${URL} : Quick Emulator(Qemu) built with the virtio-9p back-end support is vulnerable to a memory leakage issue. It could occur while querying file system extended attributes via 9pfs_list_xattr() routine. A privileged user/process inside guest could use this flaw to leak host memory resulting in Dos. Upstream patch: --------------- -> http://git.qemu.org/?p=qemu.git;a=commit;h=4ffcdef4277a91af15a3c09f7d16af072c29f3f2 @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.
