CVE-2019-12068 4 Canonical, Debian, Opensuse and 1 more 4 Ubuntu Linux, Debian Linux, Leap and 1 more 2024-11-21 2.1 LOW 3.8 LOW
In QEMU 1:4.1-1, 1:2.1+dfsg-12+deb8u6, 1:2.8+dfsg-6+deb9u8, 1:3.1+dfsg-8~deb10u1, 1:3.1+dfsg-8+deb10u2, and 1:2.1+dfsg-12+deb8u12 (fixed), when executing script in lsi_execute_script(), the LSI scsi adapter emulator advances 's->dsp' index to read next opcode. This can lead to an infinite loop if the next opcode is empty. Move the existing loop exit after 10k iterations so that it covers no-op opcodes as well.
CVE-2019-12067 4 Debian, Fedoraproject, Qemu and 1 more 5 Debian Linux, Fedora, Qemu and 2 more 2024-11-21 2.1 LOW 6.5 MEDIUM
The ahci_commit_buf function in ide/ahci.c in QEMU allows attackers to cause a denial of service (NULL dereference) when the command header 'ad->cur_cmd' is null.
CVE-2018-7858 4 Canonical, Opensuse, Qemu and 1 more 9 Ubuntu Linux, Leap, Qemu and 6 more 2024-11-21 2.1 LOW 5.5 MEDIUM
Quick Emulator (aka QEMU), when built with the Cirrus CLGD 54xx VGA Emulator support, allows local guest OS privileged users to cause a denial of service (out-of-bounds access and QEMU process crash) by leveraging incorrect region calculation when updating VGA display.
CVE-2018-7550 4 Canonical, Debian, Qemu and 1 more 9 Ubuntu Linux, Debian Linux, Qemu and 6 more 2024-11-21 4.6 MEDIUM 8.8 HIGH
The load_multiboot function in hw/i386/multiboot.c in Quick Emulator (aka QEMU) allows local guest OS users to execute arbitrary code on the QEMU host via a mh_load_end_addr value greater than mh_bss_end_addr, which triggers an out-of-bounds read or write memory access.
CVE-2018-5683 4 Canonical, Debian, Qemu and 1 more 9 Ubuntu Linux, Debian Linux, Qemu and 6 more 2024-11-21 2.1 LOW 6.0 MEDIUM
The vga_draw_text function in Qemu allows local OS guest privileged users to cause a denial of service (out-of-bounds read and QEMU process crash) by leveraging improper memory address validation.
CVE-2018-20815 1 Qemu 1 Qemu 2024-11-21 7.5 HIGH 9.8 CRITICAL
In QEMU 3.1.0, load_device_tree in device_tree.c calls the deprecated load_image function, which has a buffer overflow risk.
CVE-2018-20216 2 Canonical, Qemu 2 Ubuntu Linux, Qemu 2024-11-21 5.0 MEDIUM 7.5 HIGH
QEMU can have an infinite loop in hw/rdma/vmw/pvrdma_dev_ring.c because return values are not checked (and -1 is mishandled).
CVE-2018-20191 3 Canonical, Fedoraproject, Qemu 3 Ubuntu Linux, Fedora, Qemu 2024-11-21 5.0 MEDIUM 7.5 HIGH
hw/rdma/vmw/pvrdma_main.c in QEMU does not implement a read operation (such as uar_read by analogy to uar_write), which allows attackers to cause a denial of service (NULL pointer dereference).
CVE-2018-20126 3 Canonical, Opensuse, Qemu 3 Ubuntu Linux, Leap, Qemu 2024-11-21 2.1 LOW 5.5 MEDIUM
hw/rdma/vmw/pvrdma_cmd.c in QEMU allows create_cq and create_qp memory leaks because errors are mishandled.
CVE-2018-20125 2 Canonical, Qemu 2 Ubuntu Linux, Qemu 2024-11-21 5.0 MEDIUM 7.5 HIGH
hw/rdma/vmw/pvrdma_cmd.c in QEMU allows attackers to cause a denial of service (NULL pointer dereference or excessive memory allocation) in create_cq_ring or create_qp_rings.
CVE-2018-20124 2 Canonical, Qemu 2 Ubuntu Linux, Qemu 2024-11-21 2.1 LOW 5.5 MEDIUM
hw/rdma/rdma_backend.c in QEMU allows guest OS users to trigger out-of-bounds access via a PvrdmaSqWqe ring element with a large num_sge value.
CVE-2018-20123 3 Canonical, Fedoraproject, Qemu 3 Ubuntu Linux, Fedora, Qemu 2024-11-21 2.1 LOW 5.5 MEDIUM
pvrdma_realize in hw/rdma/vmw/pvrdma_main.c in QEMU has a Memory leak after an initialisation error.
CVE-2018-19665 2 Opensuse, Qemu 2 Leap, Qemu 2024-11-21 2.7 LOW 5.7 MEDIUM
The Bluetooth subsystem in QEMU mishandles negative values for length variables, leading to memory corruption.
CVE-2018-19489 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2024-11-21 1.9 LOW 4.7 MEDIUM
v9fs_wstat in hw/9pfs/9p.c in QEMU allows guest OS users to cause a denial of service (crash) because of a race condition during file renaming.
CVE-2018-19364 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2024-11-21 2.1 LOW 5.5 MEDIUM
hw/9pfs/cofile.c and hw/9pfs/9p.c in QEMU can modify an fid path while it is being accessed by a second thread, leading to (for example) a use-after-free outcome.
CVE-2018-18954 3 Canonical, Opensuse, Qemu 3 Ubuntu Linux, Leap, Qemu 2024-11-21 2.1 LOW 5.5 MEDIUM
The pnv_lpc_do_eccb function in hw/ppc/pnv_lpc.c in Qemu before 3.1 allows out-of-bounds write or read access to PowerNV memory.

In Qemu 3.0.0, lsi_do_msgin in hw/scsi/lsi53c895a.c allows out-of-bounds access by triggering an invalid msg_len value.
CVE-2018-18438 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Openstack 2024-11-21 2.1 LOW 5.5 MEDIUM
Qemu has integer overflows because IOReadHandler and its associated functions use a signed integer data type for a size value.
