Hi Mark,
Hopefully these are useful. I realized that my previous message was
innacurate (I forgot to apply Prasad's patch, or your v2
patchset). The only corruptions that I am continuing to see are
heap-overflows. I am guessing that most of these are due to some mututal
root cause, so the number of tests far-exceeds the actual number of
errors, but I am providing all of the crashes with unique-looking
stack-traces, just in case.
Please let me know if I can provide anything else that would help.

Title:
QEMU: use after free vulnerability in esp_do_dma() in hw/scsi/esp.c
Status in QEMU:
New
Bug description:
A use-after-free vulnerability was found in the am53c974 SCSI host bus
adapter emulation of QEMU. It could occur in the esp_do_dma() function
in hw/scsi/esp.c while handling the 'Information Transfer' command
(CMD_TI). A privileged guest user may abuse this flaw to crash the
QEMU process on the host, resulting in a denial of service or
potential code execution with the privileges of the QEMU process.
This issue was reported by Cheolwoo Myung (Seoul National University).
Original report:
Using hypervisor fuzzer, hyfuzz, I found a use-after-free issue in
am53c974 emulator of QEMU enabled ASan.
It occurs while transferring information, as it does not check the
buffer to be transferred.
A malicious guest user/process could use this flaw to crash the QEMU
process resulting in DoS scenario.
To reproduce this issue, please run the QEMU with the following command
line.
# To enable ASan option, please set configuration with the following
$ ./configure --target-list=i386-softmmu --disable-werror --enable-sanitizers
$ make
# To reproduce this issue, please run the QEMU process with the following
command line
$ ./qemu-system-i386 -m 512 -drive
file=./hyfuzz.img,index=0,media=disk,format=raw \
-device am53c974,id=scsi -device scsi-hd,drive=SysDisk \
-drive id=SysDisk,if=none,file=./disk.img
Please find attached the disk images to reproduce this issue.
