CVE-2020-14385 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2024-11-21 4.7 MEDIUM 5.5 MEDIUM
A flaw was found in the Linux kernel before 5.9-rc4. A failure of the file system metadata validator in XFS can cause an inode with a valid, user-creatable extended attribute to be flagged as corrupt. This can lead to the filesystem being shutdown, or otherwise rendered inaccessible until it is remounted, leading to a denial of service. The highest threat from this vulnerability is to system availability.
CVE-2020-14382 4 Canonical, Cryptsetup Project, Fedoraproject and 1 more 4 Ubuntu Linux, Cryptsetup, Fedora and 1 more 2024-11-21 6.8 MEDIUM 7.8 HIGH
A vulnerability was found in upstream release cryptsetup-2.2.0 where, there's a bug in LUKS2 format validation code, that is effectively invoked on every device/image presenting itself as LUKS2 container. The bug is in segments validation code in file 'lib/luks2/luks2_json_metadata.c' in function hdr_validate_segments(struct crypt_device *cd, json_object *hdr_jobj) where the code does not check for possible overflow on memory allocation used for intervals array (see statement "intervals = malloc(first_backup * sizeof(*intervals));"). Due to the bug, library can be *tricked* to expect such allocation was successful but for far less memory then originally expected. Later it may read data FROM image crafted by an attacker and actually write such data BEYOND allocated memory.
CVE-2020-14378 3 Canonical, Dpdk, Opensuse 3 Ubuntu Linux, Data Plane Development Kit, Leap 2024-11-21 2.1 LOW 3.3 LOW
An integer underflow in dpdk versions before 18.11.10 and before 19.11.5 in the `move_desc` function can lead to large amounts of CPU cycles being eaten up in a long running loop. An attacker could cause `move_desc` to get stuck in a 4,294,967,295-count iteration loop. Depending on how `vhost_crypto` is being used this could prevent other VMs or network tasks from being serviced by the busy DPDK lcore for an extended period.
CVE-2020-14377 3 Canonical, Dpdk, Opensuse 3 Ubuntu Linux, Data Plane Development Kit, Leap 2024-11-21 3.6 LOW 7.1 HIGH
A flaw was found in dpdk in versions before 18.11.10 and before 19.11.5. A complete lack of validation of attacker-controlled parameters can lead to a buffer over read. The results of the over read are then written back to the guest virtual machine memory. This vulnerability can be used by an attacker in a virtual machine to read significant amounts of host memory. The highest threat from this vulnerability is to data confidentiality and system availability.
CVE-2020-14376 3 Canonical, Dpdk, Opensuse 3 Ubuntu Linux, Data Plane Development Kit, Leap 2024-11-21 6.9 MEDIUM 7.8 HIGH
A flaw was found in dpdk in versions before 18.11.10 and before 19.11.5. A lack of bounds checking when copying iv_data from the VM guest memory into host memory can lead to a large buffer overflow. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-14375 3 Canonical, Dpdk, Opensuse 3 Ubuntu Linux, Data Plane Development Kit, Leap 2024-11-21 4.4 MEDIUM 7.8 HIGH
A flaw was found in dpdk in versions before 18.11.10 and before 19.11.5. Virtio ring descriptors, and the data they describe are in a region of memory accessible by from both the virtual machine and the host. An attacker in a VM can change the contents of the memory after vhost_crypto has validated it. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-14374 3 Canonical, Dpdk, Opensuse 3 Ubuntu Linux, Data Plane Development Kit, Leap 2024-11-21 7.2 HIGH 8.8 HIGH
A flaw was found in dpdk in versions before 18.11.10 and before 19.11.5. A flawed bounds checking in the copy_data function leads to a buffer overflow allowing an attacker in a virtual machine to write arbitrary data to any address in the vhost_crypto application. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-14367 3 Canonical, Fedoraproject, Tuxfamily 3 Ubuntu Linux, Fedora, Chrony 2024-11-21 3.6 LOW 6.0 MEDIUM
A flaw was found in chrony versions before 3.5.1 when creating the PID file under the /var/run/chrony folder. The file is created during chronyd startup while still running as the root user, and when it's opened for writing, chronyd does not check for an existing symbolic link with the same file name. This flaw allows an attacker with privileged access to create a symlink with the default PID file name pointing to any destination file in the system, resulting in data loss and a denial of service due to the path traversal.
CVE-2020-14364 6 Canonical, Debian, Fedoraproject and 3 more 7 Ubuntu Linux, Debian Linux, Fedora and 4 more 2024-11-21 4.4 MEDIUM 5.0 MEDIUM
An out-of-bounds read/write access flaw was found in the USB emulator of the QEMU in versions before 5.2.0. This issue occurs while processing USB packets from a guest when USBDevice 'setup_len' exceeds its 'data_buf[4096]' in the do_token_in, do_token_out routines. This flaw allows a guest user to crash the QEMU process, resulting in a denial of service, or the potential execution of arbitrary code with the privileges of the QEMU process on the host.
CVE-2020-14362 3 Canonical, Redhat, X.org 3 Ubuntu Linux, Enterprise Linux, Xorg-server 2024-11-21 4.6 MEDIUM 7.8 HIGH
A flaw was found in X.Org Server before xorg-x11-server 1.20.9. An Integer underflow leading to heap-buffer overflow may lead to a privilege escalation vulnerability. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
