Description Agostino Sarubbo gentoo-dev 2017-02-09 11:00:35 UTC
From ${URL} :

Quick Emulator(Qemu) built with the Virtio Crypto device emulation support is 
vulnerable to an integer overflow issue. It could occur while handling data 
encryption/decryption requests in 'virtio_crypto_handle_sym_req'.

A privileged user inside guest could use this flaw to crash the Qemu process 
resulting in DoS or potentially execute arbitrary code on the host with 
privileges of the Qemu process.
