    Summary: qemu security update

    Details: QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed. Security Fix(es): An out-of-bounds write flaw was found in the UAS (USB Attached SCSI) device emulation of QEMU in versions prior to 6.2.0-rc0. The device uses the guest supplied stream number unchecked, which can lead to out-of-bounds access to the UASDevice->data3 and UASDevice->status3 fields. A malicious guest user could use this flaw to crash QEMU or potentially achieve code execution with the privileges of the QEMU process on the host.(CVE-2021-3713)
