CVE-2016-2858
First published: Fri Mar 04 2016(Updated: )
Qemu emulator built with the Pseudo Random Number Generator(PRNG) back-end support is vulnerable to an arbitrary stack based allocation and memory corruption via random bytes issue. It could occur when a guest requests for entropy for random number generation. A user/process inside guest could use this flaw to crash the Qemu process resulting in DoS.
