Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
EUVDB-ID: #VU58358
Risk: Low
CVSSv4.0: 0.4 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2021-3975
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error in the qemuMonitorUnregister() function in qemuProcessHandleMonitorEOF. An unprivileged client with a read-only connection can trigger the use-after-free error by calling the virConnectGetAllDomainStats API and crash the application.
Update the affected package libvirt to the latest version.

EUVDB-ID: #VU62737
Risk: Low
CVSSv4.0: 4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2021-4147
CWE-ID:
CWE-667 - Improper Locking
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform a denial of service attack (DoS) on the target system.
The vulnerability exists due to double-locking error in the libvirt libxl driver in libxl/libxl_domain.c. A malicious guest can continuously reboot itself and cause libvirtd on the host to deadlock or crash, resulting in a denial of service condition
MitigationUpdate the affected package libvirt to the latest version.
