VUL-0: CVE-2018-18849: kvm,qemu: QEMU: lsi53c895a: OOB msg buffer access leads to DoS
Last modified: 2021-05-27 12:46:46 UTC
rh#1644973 An out of bounds memory access issue was found in the LSI53C895A SCSI Host Bus Adapter emulation while writing a message in lsi_do_msgin. It could occur during migration if the 'msg_len' field has an invalid value. A user/process could use this flaw to crash the Qemu process resulting in DoS.

problem already in old qemu versions, so all versions affected I think.
