| 2022-02-18 | CVE-2020-25717 | A flaw was found in the way Samba maps domain users to local users. An authenticated attacker could use this flaw to cause possible privilege escalation. | Ubuntu_linux, Debian_linux, Fedora, Codeready_linux_builder, Enterprise_linux, Enterprise_linux_desktop, Enterprise_linux_eus, Enterprise_linux_for_ibm_z_systems, Enterprise_linux_for_ibm_z_systems_eus, Enterprise_linux_for_power_big_endian, Enterprise_linux_for_power_little_endian, Enterprise_linux_for_power_little_endian_eus, Enterprise_linux_for_scientific_computing, Enterprise_linux_resilient_storage, Enterprise_linux_server, Enterprise_linux_server_aus, Enterprise_linux_server_tus, Enterprise_linux_server_update_services_for_sap_solutions, Enterprise_linux_tus, Enterprise_linux_workstation, Gluster_storage, Openstack, Virtualization, Virtualization_host, Samba | 8.1 | ||
| 2022-02-18 | CVE-2020-25719 | A flaw was found in the way Samba, as an Active Directory Domain Controller, implemented Kerberos name-based authentication. The Samba AD DC, could become confused about the user a ticket represents if it did not strictly require a Kerberos PAC and always use the SIDs found within. The result could include total domain compromise. | Ubuntu_linux, Debian_linux, Fedora, Enterprise_linux, Enterprise_linux_desktop, Enterprise_linux_eus, Enterprise_linux_for_ibm_z_systems, Enterprise_linux_for_ibm_z_systems_eus, Enterprise_linux_for_power_big_endian, Enterprise_linux_for_power_little_endian, Enterprise_linux_for_power_little_endian_eus, Enterprise_linux_for_scientific_computing, Enterprise_linux_server_aus, Enterprise_linux_server_tus, Enterprise_linux_server_update_services_for_sap_solutions, Enterprise_linux_workstation, Samba | 7.2 | ||
| 2022-02-18 | CVE-2020-25722 | Multiple flaws were found in the way samba AD DC implemented access and conformance checking of stored data. An attacker could use this flaw to cause total domain compromise. | Ubuntu_linux, Debian_linux, Fedora, Samba | 8.8 | ||
| 2022-02-18 | CVE-2021-4093 | A flaw was found in the KVM's AMD code for supporting the Secure Encrypted Virtualization-Encrypted State (SEV-ES). A KVM guest using SEV-ES can trigger out-of-bounds reads and writes in the host kernel via a malicious VMGEXIT for a string I/O instruction (for example, outs or ins) using the exit reason SVM_EXIT_IOIO. This issue results in a crash of the entire system or a potential guest-to-host escape scenario. | Ubuntu_linux, Fedora, Linux_kernel, Enterprise_linux | 8.8 | ||
| 2022-02-21 | CVE-2021-44142 | The Samba vfs_fruit module uses extended file attributes (EA, xattr) to provide "...enhanced compatibility with Apple SMB clients and interoperability with a Netatalk 3 AFP fileserver." Samba versions prior to 4.13.17, 4.14.12 and 4.15.5 with vfs_fruit configured allow out-of-bounds heap read and write via specially crafted extended file attributes. A remote attacker with write access to extended file attributes can execute arbitrary code with the privileges of smbd, typically root. | Ubuntu_linux, Debian_linux, Fedora, Codeready_linux_builder, Enterprise_linux, Enterprise_linux_desktop, Enterprise_linux_eus, Enterprise_linux_for_ibm_z_systems, Enterprise_linux_for_ibm_z_systems_eus, Enterprise_linux_for_power_big_endian, Enterprise_linux_for_power_little_endian, Enterprise_linux_for_power_little_endian_eus, Enterprise_linux_for_scientific_computing, Enterprise_linux_resilient_storage, Enterprise_linux_server, Enterprise_linux_server_aus, Enterprise_linux_server_tus, Enterprise_linux_server_update_services_for_sap_solutions, Enterprise_linux_workstation, Gluster_storage, Virtualization_host, Samba, Diskstation_manager | 8.8 | ||
| 2022-02-21 | CVE-2021-4115 | There is a flaw in polkit which can allow an unprivileged user to cause polkit to crash, due to process file descriptor exhaustion. The highest threat from this vulnerability is to availability. NOTE: Polkit process outage duration is tied to the failing process being reaped and a new one being spawned | Ubuntu_linux, Debian_linux, Fedora, Zfs_storage_appliance_kit, Polkit, Enterprise_linux | 5.5 | ||
| 2022-03-03 | CVE-2022-0492 | A vulnerability was found in the Linux kernel’s cgroup_release_agent_write in the kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly. | Ubuntu_linux, Debian_linux, Fedora, Linux_kernel, H300e, H300s, H410c, H410s, H500e, H500s, H700e, H700s, Hci_compute_node, Solidfire\,_enterprise_sds_\&_hci_storage_node, Solidfire_\&_hci_management_node, Codeready_linux_builder, Codeready_linux_builder_for_power_little_endian, Enterprise_linux, Enterprise_linux_eus, Enterprise_linux_for_ibm_z_systems, Enterprise_linux_for_ibm_z_systems_eus, Enterprise_linux_for_power_little_endian, Enterprise_linux_for_power_little_endian_eus, Enterprise_linux_for_real_time_for_nfv_tus, Enterprise_linux_for_real_time_tus, Enterprise_linux_server_aus, Enterprise_linux_server_for_power_little_endian_update_services_for_sap_solutions, Enterprise_linux_server_tus, Enterprise_linux_server_update_services_for_sap_solutions, Virtualization_host | 7.8 | ||
| 2022-03-03 | CVE-2021-3640 | A flaw use-after-free in function sco_sock_sendmsg() of the Linux kernel HCI subsystem was found in the way user calls ioct UFFDIO_REGISTER or other way triggers race condition of the call sco_conn_del() together with the call sco_sock_sendmsg() with the expected controllable faulting memory page. A privileged local user could use this flaw to crash the system or escalate their privileges on the system. | Ubuntu_linux, Debian_linux, Fedora, Linux_kernel, H300e_firmware, H300s_firmware, H410c_firmware, H410s_firmware, H500e_firmware, H500s_firmware, H700e_firmware, H700s_firmware | 7.0 | ||
| 2022-03-04 | CVE-2021-3737 | A flaw was found in python. An improperly handled HTTP response in the HTTP client code of python may allow a remote attacker, who controls the HTTP server, to make the client script enter an infinite loop, consuming CPU time. The highest threat from this vulnerability is to system availability. | Ubuntu_linux, Fedora, Hci, Management_services_for_element_software, Netapp_xcp_smb, Ontap_select_deploy_administration_utility, Xcp_nfs, Communications_cloud_native_core_binding_support_function, Communications_cloud_native_core_network_exposure_function, Communications_cloud_native_core_policy, Python, Codeready_linux_builder, Codeready_linux_builder_for_ibm_z_systems, Codeready_linux_builder_for_power_little_endian, Enterprise_linux, Enterprise_linux_for_ibm_z_systems, Enterprise_linux_for_power_little_endian | 7.5 | ||
| 2022-03-23 | CVE-2021-3748 | A use-after-free vulnerability was found in the virtio-net device of QEMU. It could occur when the descriptor's address belongs to the non direct access region, due to num_buffers being set after the virtqueue elem has been unmapped. A malicious guest could use this flaw to crash QEMU, resulting in a denial of service condition, or potentially execute code on the host with the privileges of the QEMU process. | Ubuntu_linux, Debian_linux, Fedora, Qemu, Enterprise_linux, Enterprise_linux_advanced_virtualization_eus | 7.5 |
