|---|---|---|---|---|---|---|
| 2022-02-16 | CVE-2021-3560 | It was found that polkit could be tricked into bypassing the credential checks for D-Bus requests, elevating the privileges of the requestor to the root user. This flaw could be used by an unprivileged local attacker to, for example, create a new local administrator. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | Ubuntu_linux, Debian_linux, Polkit, Openshift_container_platform, Virtualization, Virtualization_host | 7.8 | ||
| 2022-02-17 | CVE-2021-3155 | snapd 2.54.2 and earlier created ~/snap directories in user home directories without specifying owner-only permissions. This could allow a local attacker to read information that should have been private. Fixed in snapd versions 2.54.3+18.04, 2.54.3+20.04 and 2.54.3+21.10.1 | Snapd, Ubuntu_linux | 5.5 | ||
| 2022-02-17 | CVE-2021-44730 | snapd 2.54.2 did not properly validate the location of the snap-confine binary. A local attacker who can hardlink this binary to another location to cause snap-confine to execute other arbitrary binaries and hence gain privilege escalation. Fixed in snapd versions 2.54.3+18.04, 2.54.3+20.04 and 2.54.3+21.10.1 | Snapd, Ubuntu_linux, Debian_linux, Fedora | 8.8 | ||
| 2022-02-17 | CVE-2021-44731 | A race condition existed in the snapd 2.54.2 snap-confine binary when preparing a private mount namespace for a snap. This could allow a local attacker to gain root privileges by bind-mounting their own contents inside the snap's private mount namespace and causing snap-confine to execute arbitrary code and hence gain privilege escalation. Fixed in snapd versions 2.54.3+18.04, 2.54.3+20.04 and 2.54.3+21.10.1 | Snapd, Ubuntu_linux, Debian_linux, Fedora | 7.8 | ||
| 2022-02-17 | CVE-2021-4120 | snapd 2.54.2 fails to perform sufficient validation of snap content interface and layout paths, resulting in the ability for snaps to inject arbitrary AppArmor policy rules via malformed content interface and layout declarations and hence escape strict snap confinement. Fixed in snapd versions 2.54.3+18.04, 2.54.3+20.04 and 2.54.3+21.10.1 | Snapd, Ubuntu_linux, Fedora | 7.8 | ||
| 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 |
