Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

    descriptionThis update for qemu fixes the following issues : CVE-2020-7039: Fixed a heap buffer overflow in tcp_emu() routine while emulating IRC and other protocols (bsc#1161066). CVE-2019-15034: Fixed a buffer overflow in hw/display/bochs-display.c due to improper PCI config space allocation (bsc#1166379). CVE-2020-1711: Fixed an out of bounds heap buffer access iscsi_co_block_status() routine which could have allowed a remote denial of service or arbitrary code with privileges of the QEMU process on the host (bsc#1166240). CVE-2019-6778: Fixed a heap buffer overflow in tcp_emu() routine while emulating the identification protocol and copying message data to a socket buffer (bsc#1123156). CVE-2020-8608: Fixed a heap buffer overflow in tcp_emu() routine while emulating IRC and other protocols (bsc#1163018). CVE-2019-20382: Fixed a memory leak in the VNC display driver which could have led to exhaustion of the host memory leading to a potential Denial of service (bsc#1165776). Fixed live migration errors (bsc#1154790, bsc#1156794, bsc#1156642). Fixed an issue where migrating VMs on KVM gets missing features:ospke error (bsc#1162729). Fixed an issue where booting up a guest system with mdev passthrough device as installation device was failing (bsc#1158880).

    descriptionIt was discovered that QEMU incorrectly handled bochs-display devices. A local attacker in a guest could use this to cause a denial of service or possibly execute arbitrary code in the host. This issue only affected Ubuntu 19.10. (CVE-2019-15034) It was discovered that QEMU incorrectly handled memory during certain VNC operations. A remote attacker could possibly use this issue to cause QEMU to consume resources, resulting in a denial of service. This issue only affected Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, and Ubuntu 19.10. (CVE-2019-20382) It was discovered that QEMU incorrectly generated QEMU Pointer Authentication signatures on ARM. A local attacker could possibly use this issue to bypass PAuth. This issue only affected Ubuntu 19.10. (CVE-2020-10702) Ziming Zhang discovered that QEMU incorrectly handled ATI VGA emulation. A local attacker in a guest could use this issue to cause QEMU to crash, resulting in a denial of service. This issue only affected Ubuntu 20.04 LTS. (CVE-2020-11869) Aviv Sasson discovered that QEMU incorrectly handled Slirp networking. A remote attacker could use this issue to cause QEMU to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, and Ubuntu 19.10. (CVE-2020-1983).

this issue to bypass PAuth. This issue only affected Ubuntu 19.10.
(CVE-2020-10702)

Ziming Zhang discovered that QEMU incorrectly handled ATI VGA
emulation. A local attacker in a guest could use this issue to cause
QEMU to crash, resulting in a denial of service. This issue only
affected Ubuntu 20.04 LTS. (CVE-2020-11869)

Aviv Sasson discovered that QEMU incorrectly handled Slirp networking.
A remote attacker could use this issue to cause QEMU to crash,

  • NASL familySuSE Local Security Checks
    NASL idSUSE_SU-2020-0844-1.NASL
    descriptionThis update for qemu fixes the following issues : CVE-2020-7039: Fixed a heap buffer overflow in tcp_emu() routine while emulating IRC and other protocols (bsc#1161066). CVE-2019-15034: Fixed a buffer overflow in hw/display/bochs-display.c due to improper PCI config space allocation (bsc#1166379). CVE-2020-1711: Fixed an out of bounds heap buffer access iscsi_co_block_status() routine which could have allowed a remote denial of service or arbitrary code with privileges of the QEMU process on the host (bsc#1166240). CVE-2019-6778: Fixed a heap buffer overflow in tcp_emu() routine while emulating the identification protocol and copying message data to a socket buffer (bsc#1123156). CVE-2020-8608: Fixed a heap buffer overflow in tcp_emu() routine while emulating IRC and other protocols (bsc#1163018). CVE-2019-20382: Fixed a memory leak in the VNC display driver which could have led to exhaustion of the host memory leading to a potential Denial of service (bsc#1165776). Fixed a live migration error (bsc#1154790). Fixed an issue where migrating VMs on KVM gets missing features:ospke error (bsc#1162729). Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
