From ${URL} : An information leakage issue was found in the SLiRP networking implementation of the QEMU emulator. It occurs in tcp_emu() routine while emulating Identification protocol, when crafted messages are sent to make it return uninitialized variables. A user/process could use this flaw to read uninitialised stack memory contents from the QEMU process resulting in information leakage. Upstream patch: --------------- -> https://lists.gnu.org/archive/html/qemu-devel/2019-03/msg01871.html @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.
