"This update for qemu fixes the following issues :

  - Fixed potential privilege escalation in virtfs
    (CVE-2021-20181 bsc#1182137)

  - Fixed out-of-bound access in iscsi (CVE-2020-11947
    bsc#1180523)

  - Fixed out-of-bound access in vmxnet3 emulation
    (CVE-2021-20203 bsc#1181639)

  - Fixed out-of-bound access in ARM interrupt handling
    (CVE-2021-20221 bsc#1181933)

  - Fixed vfio-pci device on s390 enters error state
    (bsc#1179717 bsc#1179719)

  - Fixed 'Failed to try-restart [email protected]' error
    while updating the qemu-guest-agent. (bsc#1178565)

  - Apply fixes to qemu scsi passthrough with respect to
    timeout and error conditions, including using more
    correct status codes. Add more qemu tracing which helped
    track down these issues (bsc#1178049)
