NONE Summary
QEMU, through version 2.10 and through version 3.1.0, is vulnerable to an out-of-bounds read of up to 128 bytes in the hw/i2c/i2c-ddc.c:i2c_ddc() function. A local attacker with permission to execute i2c commands could exploit this to read stack memory of the qemu process on the host.

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.

An attacker inside the guest could use this issue to read or write arbitrary files and cause a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 18.10. (CVE-2018-16867) Michael Hanselmann discovered that QEMU incorrectly handled the Media Transfer Protocol (MTP). An attacker inside the guest could use this issue to read arbitrary files, contrary to expectations. This issue only affected Ubuntu 18.04 LTS and Ubuntu 18.10.

An attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service. (CVE-2018-19489) Li Quang and Saar Amar discovered multiple issues in the QEMU PVRDMA device. An attacker inside the guest could use these issues to cause a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 18.10.

Reading and writing of arbitrary files is allowed when a guest device is mounted which may lead to a denial of service scenario or possibly lead to code execution on the host.(CVE-2018-16867) - A flaw was found in QEMU's Media Transfer Protocol (MTP). The code opening files in usb_mtp_get_object and usb_mtp_get_partial_object and directories in usb_mtp_object_readdir doesn't consider that the underlying filesystem may have changed since the time lstat(2) was called in usb_mtp_object_alloc, a classical TOCTTOU problem. An attacker with write access to the host filesystem, shared with a guest, can use this property to navigate the host filesystem in the context of the QEMU process and read any file the QEMU process has access to. Access to the filesystem may be local or via a network share protocol such as CIFS.(CVE-2018-16872) - 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-2018-19364) - 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-2018-19489) - 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-2018-20191) - QEMU, through version 2.10 and through version 3.1.0, is vulnerable to an out-of-bounds read of up to 128 bytes in the hw/i2c/i2c-ddc.c:i2c_ddc() function. A local attacker with permission to execute i2c commands could exploit this to read stack memory of the qemu process on the host.(CVE-2019-3812) - In QEMU 3.0.0, tcp_emu in slirp/tcp_subr.c has a heap-based buffer overflow.(CVE-2019-6778) Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.
