CVE-2017-8284 1 Qemu 1 Qemu 2024-11-21 6.9 MEDIUM 7.0 HIGH
The disas_insn function in target/i386/translate.c in QEMU before 2.9.0, when TCG mode without hardware acceleration is used, does not limit the instruction size, which allows local users to gain privileges by creating a modified basic block that injects code into a setuid program, as demonstrated by procmail. NOTE: the vendor has stated "this bug does not violate any security guarantees QEMU makes.
CVE-2017-8112 2 Debian, Qemu 2 Debian Linux, Qemu 2024-11-21 4.9 MEDIUM 6.5 MEDIUM
hw/scsi/vmw_pvscsi.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (infinite loop and CPU consumption) via the message ring page count.
CVE-2017-8086 2 Debian, Qemu 2 Debian Linux, Qemu 2024-11-21 4.9 MEDIUM 6.5 MEDIUM
Memory leak in the v9fs_list_xattr function in hw/9pfs/9p-xattr.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (memory consumption) via vectors involving the orig_value variable.
CVE-2017-7980 4 Canonical, Debian, Qemu and 1 more 12 Ubuntu Linux, Debian Linux, Qemu and 9 more 2024-11-21 4.6 MEDIUM 7.8 HIGH
Heap-based buffer overflow in Cirrus CLGD 54xx VGA Emulator in Quick Emulator (Qemu) 2.8 and earlier allows local guest OS users to execute arbitrary code or cause a denial of service (crash) via vectors related to a VNC client updating its display after a VGA operation.
CVE-2017-7718 2 Debian, Qemu 2 Debian Linux, Qemu 2024-11-21 2.1 LOW 5.5 MEDIUM
hw/display/cirrus_vga_rop.h in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (out-of-bounds read and QEMU process crash) via vectors related to copying VGA data via the cirrus_bitblt_rop_fwd_transp_ and cirrus_bitblt_rop_fwd_ functions.
CVE-2017-7539 2 Qemu, Redhat 4 Qemu, Enterprise Linux, Openstack and 1 more 2024-11-21 5.0 MEDIUM 5.3 MEDIUM
An assertion-failure flaw was found in Qemu before 2.10.1, in the Network Block Device (NBD) server's initial connection negotiation, where the I/O coroutine was undefined. This could crash the qemu-nbd server if a client sent unexpected data during connection negotiation. A remote user or process could use this flaw to crash the qemu-nbd server resulting in denial of service.
CVE-2017-7493 2 Debian, Qemu 2 Debian Linux, Qemu 2024-11-21 4.6 MEDIUM 7.8 HIGH
Quick Emulator (Qemu) built with the VirtFS, host directory sharing via Plan 9 File System(9pfs) support, is vulnerable to an improper access control issue. It could occur while accessing virtfs metadata files in mapped-file security mode. A guest user could use this flaw to escalate their privileges inside guest.
CVE-2017-7471 1 Qemu 1 Qemu 2024-11-21 7.7 HIGH 9.0 CRITICAL
Quick Emulator (Qemu) built with the VirtFS, host directory sharing via Plan 9 File System (9pfs) support, is vulnerable to an improper access control issue. It could occur while accessing files on a shared host directory. A privileged user inside guest could use this flaw to access host file system beyond the shared folder and potentially escalating their privileges on a host.
