CVE-2022-20698 3 Canonical, Clamav, Debian 3 Ubuntu Linux, Clamav, Debian Linux 2024-11-21 5.0 MEDIUM 7.5 HIGH
A vulnerability in the OOXML parsing module in Clam AntiVirus (ClamAV) Software version 0.104.1 and LTS version 0.103.4 and prior versions could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device. The vulnerability is due to improper checks that may result in an invalid pointer read. An attacker could exploit this vulnerability by sending a crafted OOXML file to an affected device. An exploit could allow the attacker to cause the ClamAV scanning process to crash, resulting in a denial of service condition.
CVE-2022-1184 4 Canonical, Debian, Linux and 1 more 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more 2024-11-21 N/A 5.5 MEDIUM
A use-after-free flaw was found in fs/ext4/namei.c:dx_insert_block() in the Linux kernel’s filesystem sub-component. This flaw allows a local attacker with a user privilege to cause a denial of service.
CVE-2022-1055 5 Canonical, Fedoraproject, Linux and 2 more 20 Ubuntu Linux, Fedora, Linux Kernel and 17 more 2024-11-21 4.6 MEDIUM 7.8 HIGH
A use-after-free exists in the Linux Kernel in tc_new_tfilter that could allow a local attacker to gain privilege escalation. The exploit requires unprivileged user namespaces. We recommend upgrading past commit 04c2a47ffb13c29778e2a14e414ad4cb5a5db4b5
CVE-2022-0492 6 Canonical, Debian, Fedoraproject and 3 more 30 Ubuntu Linux, Debian Linux, Fedora and 27 more 2024-11-21 6.9 MEDIUM 7.8 HIGH
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.
CVE-2022-0319 4 Apple, Canonical, Debian and 1 more 4 Macos, Ubuntu Linux, Debian Linux and 1 more 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
Out-of-bounds Read in vim/vim prior to 8.2.
CVE-2021-4120 2 Canonical, Fedoraproject 3 Snapd, Ubuntu Linux, Fedora 2024-11-21 4.6 MEDIUM 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 2.1 LOW 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 7.2 HIGH 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 7 Advanced Intrusion Detection Environment, Ubuntu Linux, Debian Linux and 4 more 2024-11-21 7.2 HIGH 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 5.8 MEDIUM 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 6.9 MEDIUM 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 6.9 MEDIUM 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 5 Ubuntu Linux, Debian Linux, Django and 2 more 2024-11-21 7.5 HIGH 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-2021-3975 5 Canonical, Debian, Fedoraproject and 2 more 14 Ubuntu Linux, Debian Linux, Fedora and 11 more 2024-11-21 N/A 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 7.2 HIGH 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 4 Ubuntu Linux, Fedora, Openvswitch and 1 more 2024-11-21 N/A 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 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2024-11-21 6.9 MEDIUM 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-2021-3747 2 Apple, Canonical 2 Macos, Multipass 2024-11-21 4.6 MEDIUM 8.8 HIGH
The MacOS version of Multipass, version 1.7.0, fixed in 1.7.2, accidentally installed the application directory with incorrect owner.
CVE-2021-3737 6 Canonical, Fedoraproject, Netapp and 3 more 17 Ubuntu Linux, Fedora, Hci and 14 more 2024-11-21 7.1 HIGH 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 4.7 MEDIUM 6.5 MEDIUM
