NASL family Huawei Local Security Checks NASL id EULEROS_SA-2019-1405.NASL description According to the versions of the qemu-kvm packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities : - An integer overflow issue was found in the NE200 NIC emulation. It could occur while receiving packets from the network, if the size value was greater than INT_MAX. Such overflow would lead to stack buffer overflow issue. A user inside guest could use this flaw to crash the QEMU process, resulting in DoS scenario. (CVE-2018-10839) - qmp_guest_file_read in qga/commands-posix.c and qga/commands-win32.c in qemu-ga (aka QEMU Guest Agent) in QEMU 2.12.50 has an integer overflow causing a g_malloc0() call to trigger a segmentation fault when trying to allocate a large memory chunk. The vulnerability can be exploited by sending a crafted QMP command (including guest-file-read with a large count value) to the agent via the listening socket.(CVE-2018-12617) - Qemu before version 2.9 is vulnerable to an improper link following when built with the VirtFS. 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. (CVE-2016-9602) - Quick Emulator (QEMU), compiled with the PC System Emulator with multiboot feature support, is vulnerable to an OOB r/w memory access issue. The issue could occur while loading a kernel image during the guest boot, if mh_load_end_addr address is greater than the mh_bss_end_addr address. A user or process could use this flaw to potentially achieve arbitrary code execution on a host.(CVE-2018-7550) - An out-of-bounds read access issue was found in the VGA display emulator built into the Quick emulator (QEMU). It could occur while reading VGA memory to update graphics display. A privileged user/process inside guest could use this flaw to crash the QEMU process on the host resulting in denial of service situation.(CVE-2017-13672) - An assert failure issue was found in the VGA display emulator built into the Quick emulator (QEMU). It could occur while updating graphics display, due to miscalculating region for dirty bitmap snapshot in split screen mode. A privileged user/process inside guest could use this flaw to crash the QEMU process on the host resulting in denial of service. (CVE-2017-13673) - The Network Block Device (NBD) server in Quick Emulator (QEMU), is vulnerable to a denial of service issue. It could occur if a client sent large option requests, making the server waste CPU time on reading up to 4GB per request. A client could use this flaw to keep the NBD server from serving other requests, resulting in DoS.(CVE-2017-15119) - QEMU (aka Quick Emulator) before 2.9.0, when built with the USB OHCI Emulation support, allows local guest OS users to cause a denial of service (infinite loop) by leveraging an incorrect return value, a different vulnerability than CVE-2017-6505.(CVE-2017-9330) - Integer overflow in the macro ROUND_UP (n, d) in Quick Emulator (Qemu) allows a user to cause a denial of service (Qemu process crash). (CVE-2017-18043) - VNC server implementation in Quick Emulator (QEMU) was found to be vulnerable to an unbounded memory allocation issue, as it did not throttle the framebuffer updates sent to its client. If the client did not consume these updates, VNC server allocates growing memory to hold onto this data. A malicious remote VNC client could use this flaw to cause DoS to the server host.(CVE-2017-15124) - A memory leakage issue was found in the I/O channels websockets implementation of the Quick Emulator (QEMU). It could occur while sending screen updates to a client, which is slow to read and process them further. A privileged guest user could use this flaw to cause a denial of service on the host and/or potentially crash the QEMU process instance on the host.(CVE-2017-15268) - Quick Emulator (QEMU), compiled with the PC System Emulator with multiboot feature support, is vulnerable to an OOB r/w memory access issue. The issue could occur due to an integer overflow while loading a kernel image during a guest boot. A user or process could use this flaw to potentially achieve arbitrary code execution on a host.(CVE-2017-14167) - Memory leak in QEMU (aka Quick Emulator), when built with IDE AHCI Emulation support, allows local guest OS privileged users to cause a denial of service (memory consumption) by repeatedly hot-unplugging the AHCI device.(CVE-2017-9373) - Memory leak in the serial_exit_core function in hw/char/serial.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (host memory consumption and QEMU process crash) via a large number of device unplug operations.(CVE-2017-5579) - ** DISPUTED ** 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.

NASL family Huawei Local Security Checks NASL id EULEROS_SA-2020-1573.NASL description According to the versions of the qemu-kvm packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities : - The ohci_service_ed_list function in hw/usb/hcd-ohci.c in QEMU (aka Quick Emulator) before 2.9.0 allows local guest OS users to cause a denial of service (infinite loop) via vectors involving the number of link endpoint list descriptors, a different vulnerability than CVE-2017-9330.(CVE-2017-6505) - ** DISPUTED ** QEMU 3.0.0 has an Integer Overflow because the qga/commands*.c files do not check the length of the argument list or the number of environment variables. NOTE: This has been disputed as not exploitable.(CVE-2019-12247) - ** DISPUTED ** An issue was discovered in ide_dma_cb() in hw/ide/core.c in QEMU 2.4.0 through 4.2.0.

It could occur while receiving packets from the network, if the size value was greater than INT_MAX. Such overflow would lead to stack buffer overflow issue. A user inside guest could use this flaw to crash the QEMU process, resulting in DoS scenario. (CVE-2018-10839) - qmp_guest_file_read in qga/commands-posix.c and qga/commands-win32.c in qemu-ga (aka QEMU Guest Agent) in QEMU 2.12.50 has an integer overflow causing a g_malloc0() call to trigger a segmentation fault when trying to allocate a large memory chunk. The vulnerability can be exploited by sending a crafted QMP command (including guest-file-read with a large count value) to the agent via the listening socket.(CVE-2018-12617) - Qemu before version 2.9 is vulnerable to an improper link following when built with the VirtFS. 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. (CVE-2016-9602) - Quick Emulator (QEMU), compiled with the PC System Emulator with multiboot feature support, is vulnerable to an OOB r/w memory access issue. The issue could occur while loading a kernel image during the guest boot, if mh_load_end_addr address is greater than the mh_bss_end_addr address. A user or process could use this flaw to potentially achieve arbitrary code execution on a host.(CVE-2018-7550) - An out-of-bounds read access issue was found in the VGA display emulator built into the Quick emulator (QEMU). It could occur while reading VGA memory to update graphics display. A privileged user/process inside guest could use this flaw to crash the QEMU process on the host resulting in denial of service situation.(CVE-2017-13672) - An assert failure issue was found in the VGA display emulator built into the Quick emulator (QEMU). It could occur while updating graphics display, due to miscalculating region for dirty bitmap snapshot in split screen mode.
