| CVE-2021-4120 | 2 Canonical, Fedoraproject | 3 Snapd, Ubuntu Linux, Fedora | 2024-11-21 | 8.2 High |
| 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 | ||||
| CVE-2021-4115 | 6 Canonical, Debian, Fedoraproject and 3 more | 6 Ubuntu Linux, Debian Linux, Fedora and 3 more | 2024-11-21 | 5.5 Medium |
| 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 | ||||
| CVE-2021-4093 | 4 Canonical, Fedoraproject, Linux and 1 more | 4 Ubuntu Linux, Fedora, Linux Kernel and 1 more | 2024-11-21 | 8.8 High |
| 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. | ||||
| CVE-2021-45417 | 5 Advanced Intrusion Detection Environment Project, Canonical, Debian and 2 more | 11 Advanced Intrusion Detection Environment, Ubuntu Linux, Debian Linux and 8 more | 2024-11-21 | 7.8 High |
| AIDE before 0.17.4 allows local users to obtain root privileges via crafted file metadata (such as XFS extended attributes or tmpfs ACLs), because of a heap-based buffer overflow. | ||||
| CVE-2021-45079 | 4 Canonical, Debian, Fedoraproject and 1 more | 5 Ubuntu Linux, Debian Linux, Extra Packages For Enterprise Linux and 2 more | 2024-11-21 | 9.1 Critical |
| In strongSwan before 5.9.5, a malicious responder can send an EAP-Success message too early without actually authenticating the client and (in the case of EAP methods with mutual authentication and EAP-only authentication for IKEv2) even without server authentication. | ||||
| CVE-2021-44731 | 3 Canonical, Debian, Fedoraproject | 4 Snapd, Ubuntu Linux, Debian Linux and 1 more | 2024-11-21 | 7.8 High |
| 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 | ||||
| CVE-2021-44730 | 3 Canonical, Debian, Fedoraproject | 4 Snapd, Ubuntu Linux, Debian Linux and 1 more | 2024-11-21 | 7.8 High |
| 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 | ||||
| CVE-2021-44420 | 5 Canonical, Debian, Djangoproject and 2 more | 7 Ubuntu Linux, Debian Linux, Django and 4 more | 2024-11-21 | 7.3 High |
| In Django 2.2 before 2.2.25, 3.1 before 3.1.14, and 3.2 before 3.2.10, HTTP requests for URLs with trailing newlines could bypass upstream access control based on URL paths. | ||||
| CVE-2021-44142 | 6 Canonical, Debian, Fedoraproject and 3 more | 28 Ubuntu Linux, Debian Linux, Fedora and 25 more | 2024-11-21 | 8.8 High |
| 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. | ||||
| CVE-2021-3975 | 5 Canonical, Debian, Fedoraproject and 2 more | 15 Ubuntu Linux, Debian Linux, Fedora and 12 more | 2024-11-21 | 6.5 Medium |
| A use-after-free flaw was found in libvirt. The qemuMonitorUnregister() function in qemuProcessHandleMonitorEOF is called using multiple threads without being adequately protected by a monitor lock. This flaw could be triggered by the virConnectGetAllDomainStats API when the guest is shutting down. An unprivileged client with a read-only connection could use this flaw to perform a denial of service attack by causing the libvirt daemon to crash. | ||||
| CVE-2021-3939 | 1 Canonical | 2 Accountsservice, Ubuntu Linux | 2024-11-21 | 7.8 High |
| Ubuntu-specific modifications to accountsservice (in patch file debian/patches/0010-set-language.patch) caused the fallback_locale variable, pointing to static storage, to be freed, in the user_change_language_authorized_cb function. This is reachable via the SetLanguage dbus function. This is fixed in versions 0.6.55-0ubuntu12~20.04.5, 0.6.55-0ubuntu13.3, 0.6.55-0ubuntu14.1. | ||||
| CVE-2021-3905 | 4 Canonical, Fedoraproject, Openvswitch and 1 more | 5 Ubuntu Linux, Fedora, Openvswitch and 2 more | 2024-11-21 | 7.5 High |
| A memory leak was found in Open vSwitch (OVS) during userspace IP fragmentation processing. An attacker could use this flaw to potentially exhaust available memory by keeping sending packet fragments. | ||||
| CVE-2021-3748 | 5 Canonical, Debian, Fedoraproject and 2 more | 7 Ubuntu Linux, Debian Linux, Fedora and 4 more | 2024-11-21 | 7.5 High |
| 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. | ||||
| CVE-2021-3737 | 6 Canonical, Fedoraproject, Netapp and 3 more | 18 Ubuntu Linux, Fedora, Hci and 15 more | 2024-11-21 | 7.5 High |
| 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. | ||||
| CVE-2021-3710 | 1 Canonical | 2 Apport, Ubuntu Linux | 2024-11-21 | 6.5 Medium |

| CVE-2021-3640 | 6 Canonical, Debian, Fedoraproject and 3 more | 23 Ubuntu Linux, Debian Linux, Fedora and 20 more | 2024-11-21 | 7.0 High |
| 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. | ||||
| CVE-2021-3600 | 4 Canonical, Fedoraproject, Linux and 1 more | 4 Ubuntu Linux, Fedora, Linux Kernel and 1 more | 2024-11-21 | 7.8 High |
| It was discovered that the eBPF implementation in the Linux kernel did not properly track bounds information for 32 bit registers when performing div and mod operations. A local attacker could use this to possibly execute arbitrary code. | ||||
| CVE-2021-3492 | 1 Canonical | 1 Ubuntu Linux | 2024-11-21 | 8.8 High |
| Shiftfs, an out-of-tree stacking file system included in Ubuntu Linux kernels, did not properly handle faults occurring during copy_from_user() correctly. These could lead to either a double-free situation or memory not being freed at all. An attacker could use this to cause a denial of service (kernel memory exhaustion) or gain privileges via executing arbitrary code. AKA ZDI-CAN-13562. | ||||
| CVE-2021-3491 | 2 Canonical, Linux | 2 Ubuntu Linux, Linux Kernel | 2024-11-21 | 7.8 High |
| The io_uring subsystem in the Linux kernel allowed the MAX_RW_COUNT limit to be bypassed in the PROVIDE_BUFFERS operation, which led to negative values being usedin mem_rw when reading /proc/<PID>/mem. This could be used to create a heap overflow leading to arbitrary code execution in the kernel. It was addressed via commit d1f82808877b ("io_uring: truncate lengths larger than MAX_RW_COUNT on provide buffers") (v5.13-rc1) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37. It was introduced in ddf0322db79c ("io_uring: add IORING_OP_PROVIDE_BUFFERS") (v5.7-rc1). | ||||
