Vulnerabilities > CVE-2019-15034 - Classic Buffer Overflow vulnerability in Qemu 4.0.0
Attack vector
LOCAL Attack complexity
HIGH Privileges required
LOW Confidentiality impact
LOW Integrity impact
LOW Availability impact
HIGH Summary
hw/display/bochs-display.c in QEMU 4.0.0 does not ensure a sufficient PCI config space allocation, leading to a buffer overflow involving the PCIe extended config space.
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.

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).
