The megasas_dcmd_cfg_read function in hw/scsi/megasas.c in QEMU, when built with MegaRAID SAS 8708EM2 Host Bus Adapter emulation support, uses an uninitialized variable, which allows local guest administrators to read host memory via vectors involving a MegaRAID Firmware Interface (MFI) command.
CVE-2016-5238 3 Canonical, Debian, Qemu 3 Ubuntu Linux, Debian Linux, Qemu 2020-10-21 2.1 LOW 4.4 MEDIUM
The get_cmd function in hw/scsi/esp.c in QEMU might allow local guest OS administrators to cause a denial of service (out-of-bounds write and QEMU process crash) via vectors related to reading from the information transfer buffer in non-DMA mode.
CVE-2016-5106 3 Canonical, Debian, Qemu 3 Ubuntu Linux, Debian Linux, Qemu 2020-10-21 1.9 LOW 6.0 MEDIUM
The megasas_dcmd_set_properties function in hw/scsi/megasas.c in QEMU, when built with MegaRAID SAS 8708EM2 Host Bus Adapter emulation support, allows local guest administrators to cause a denial of service (out-of-bounds write access) via vectors involving a MegaRAID Firmware Interface (MFI) command.
CVE-2016-5107 3 Canonical, Debian, Qemu 3 Ubuntu Linux, Debian Linux, Qemu 2020-10-21 1.9 LOW 6.0 MEDIUM
The megasas_lookup_frame function in QEMU, when built with MegaRAID SAS 8708EM2 Host Bus Adapter emulation support, allows local guest OS administrators to cause a denial of service (out-of-bounds read and crash) via unspecified vectors.
CVE-2016-8578 3 Debian, Opensuse, Qemu 3 Debian Linux, Leap, Qemu 2020-10-21 2.1 LOW 6.0 MEDIUM
The v9fs_iov_vunmarshal function in fsdev/9p-iov-marshal.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (NULL pointer dereference and QEMU process crash) by sending an empty string parameter to a 9P operation.
CVE-2016-8667 3 Debian, Opensuse, Qemu 3 Debian Linux, Leap, Qemu 2020-10-21 2.1 LOW 6.0 MEDIUM
The rc4030_write function in hw/dma/rc4030.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (divide-by-zero error and QEMU process crash) via a large interval timer reload value.
CVE-2016-8668 2 Opensuse, Qemu 2 Leap, Qemu 2020-10-21 2.1 LOW 6.0 MEDIUM
The rocker_io_writel function in hw/net/rocker/rocker.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (out-of-bounds read and QEMU process crash) by leveraging failure to limit DMA buffer size.
CVE-2016-9104 3 Debian, Opensuse, Qemu 3 Debian Linux, Leap, Qemu 2020-10-21 2.1 LOW 4.4 MEDIUM
Multiple integer overflows in the (1) v9fs_xattr_read and (2) v9fs_xattr_write functions in hw/9pfs/9p.c in QEMU (aka Quick Emulator) allow local guest OS administrators to cause a denial of service (QEMU process crash) via a crafted offset, which triggers an out-of-bounds access.
