6 vulnerabilities found for QEMU by The QEMU Project
CVE-2020-10702 (GCVE-0-2020-10702)
Vulnerability from cvelistv5 – Published: 2020-06-04 17:31 – Updated: 2024-08-04 11:06
VLAI?
Summary
A flaw was found in QEMU in the implementation of the Pointer Authentication (PAuth) support for ARM introduced in version 4.0 and fixed in version 5.0.0. A general failure of the signature generation process caused every PAuth-enforced pointer to be signed with the same signature. A local attacker could obtain the signature of a protected pointer and abuse this flaw to bypass PAuth protection for all programs running on QEMU.

CVE-2020-10717 (GCVE-0-2020-10717)
Vulnerability from cvelistv5 – Published: 2020-05-04 00:00 – Updated: 2024-08-04 11:14
VLAI?
Summary
A potential DoS flaw was found in the virtio-fs shared file system daemon (virtiofsd) implementation of the QEMU version >= v5.0. Virtio-fs is meant to share a host file system directory with a guest via virtio-fs device. If the guest opens the maximum number of file descriptors under the shared directory, a denial of service may occur. This flaw allows a guest user/process to cause this denial of service on the host.

CVE-2019-3812 (GCVE-0-2019-3812)
Vulnerability from cvelistv5 – Published: 2019-02-19 14:00 – Updated: 2024-08-04 19:19
VLAI?
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.

CVE-2020-10702 (GCVE-0-2020-10702)
Vulnerability from nvd – Published: 2020-06-04 17:31 – Updated: 2024-08-04 11:06
VLAI?
Summary
A flaw was found in QEMU in the implementation of the Pointer Authentication (PAuth) support for ARM introduced in version 4.0 and fixed in version 5.0.0. A general failure of the signature generation process caused every PAuth-enforced pointer to be signed with the same signature. A local attacker could obtain the signature of a protected pointer and abuse this flaw to bypass PAuth protection for all programs running on QEMU.

CVE-2020-10717 (GCVE-0-2020-10717)
Vulnerability from nvd – Published: 2020-05-04 00:00 – Updated: 2024-08-04 11:14
VLAI?
Summary
A potential DoS flaw was found in the virtio-fs shared file system daemon (virtiofsd) implementation of the QEMU version >= v5.0. Virtio-fs is meant to share a host file system directory with a guest via virtio-fs device. If the guest opens the maximum number of file descriptors under the shared directory, a denial of service may occur. This flaw allows a guest user/process to cause this denial of service on the host.

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.
