PARTIAL Summary
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.
Vulnerable Configurations
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.

The Common Vulnerabilities and Exposures project identifies the following problems : CVE-2016-9603 qemu-kvm built with the Cirrus CLGD 54xx VGA Emulator and the VNC display driver support is vulnerable to a heap buffer overflow issue. It could occur when Vnc client attempts to update its display after a vga operation is performed by a guest. A privileged user/process inside guest could use this flaw to crash the Qemu process resulting in DoS OR potentially leverage it to execute arbitrary code on the host with privileges of the Qemu process. CVE-2017-7718 qemu-kvm built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to an out-of-bounds access issue. It could occur while copying VGA data via bitblt functions cirrus_bitblt_rop_fwd_transp_ and/or cirrus_bitblt_rop_fwd_. A privileged user inside guest could use this flaw to crash the Qemu process resulting in DoS. CVE-2017-7980 qemu-kvm built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to an out-of-bounds r/w access issues. It could occur while copying VGA data via various bitblt functions. A privileged user inside guest could use this flaw to crash the Qemu process resulting in DoS OR potentially execute arbitrary code on a host with privileges of Qemu process on the host.

A privileged attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service. (CVE-2017-7718) Li Qiang and Jiangxin discovered that QEMU incorrectly handled the Cirrus VGA device when being used with a VNC connection. A privileged attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service, or possibly execute arbitrary code on the host. In the default installation, when QEMU is used with libvirt, attackers would be isolated by the libvirt AppArmor profile. (CVE-2017-7980) Jiang Xin discovered that QEMU incorrectly handled the audio subsystem. A privileged attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service. (CVE-2017-8309) Jiang Xin discovered that QEMU incorrectly handled the input subsystem. A privileged attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service. This issue only affected Ubuntu 16.04 LTS, Ubuntu 16.10 and Ubuntu 17.04.
