| CVE-2020-14361 | 3 Canonical, Redhat, X.org | 3 Ubuntu Linux, Enterprise Linux, Xorg-server | 2024-08-04 | 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. | ||||
| CVE-2020-14377 | 3 Canonical, Dpdk, Opensuse | 3 Ubuntu Linux, Data Plane Development Kit, Leap | 2024-08-04 | 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-2020-14362 | 3 Canonical, Redhat, X.org | 3 Ubuntu Linux, Enterprise Linux, Xorg-server | 2024-08-04 | 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. | ||||
| CVE-2020-14378 | 3 Canonical, Dpdk, Opensuse | 3 Ubuntu Linux, Data Plane Development Kit, Leap | 2024-08-04 | 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-2020-14367 | 3 Canonical, Fedoraproject, Tuxfamily | 3 Ubuntu Linux, Fedora, Chrony | 2024-08-04 | 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-2020-14355 | 5 Canonical, Debian, Opensuse and 2 more | 12 Ubuntu Linux, Debian Linux, Leap and 9 more | 2024-08-04 | 6.6 Medium |
| Multiple buffer overflow vulnerabilities were found in the QUIC image decoding process of the SPICE remote display system, before spice-0.14.2-1. Both the SPICE client (spice-gtk) and server are affected by these flaws. These flaws allow a malicious client or server to send specially crafted messages that, when processed by the QUIC image compression algorithm, result in a process crash or potential code execution. | ||||
| CVE-2020-14347 | 4 Canonical, Debian, Redhat and 1 more | 4 Ubuntu Linux, Debian Linux, Enterprise Linux and 1 more | 2024-08-04 | 5.5 Medium |

| CVE-2020-14346 | 3 Canonical, Redhat, X.org | 3 Ubuntu Linux, Enterprise Linux, Xorg-server | 2024-08-04 | 7.8 High |
| A flaw was found in xorg-x11-server before 1.20.9. An integer underflow in the X input extension protocol decoding in the X server may lead to arbitrary access of memory contents. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||||
| CVE-2020-14350 | 5 Canonical, Debian, Opensuse and 2 more | 9 Ubuntu Linux, Debian Linux, Leap and 6 more | 2024-08-04 | 7.3 High |
| It was found that some PostgreSQL extensions did not use search_path safely in their installation script. An attacker with sufficient privileges could use this flaw to trick an administrator into executing a specially crafted script, during the installation or update of such extension. This affects PostgreSQL versions before 12.4, before 11.9, before 10.14, before 9.6.19, and before 9.5.23. | ||||
| CVE-2020-14345 | 3 Canonical, Redhat, X.org | 3 Ubuntu Linux, Enterprise Linux, X Server | 2024-08-04 | 7.8 High |
| A flaw was found in X.Org Server before xorg-x11-server 1.20.9. An Out-Of-Bounds access in XkbSetNames function may lead to a privilege escalation vulnerability. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||||
| CVE-2020-14344 | 5 Canonical, Fedoraproject, Opensuse and 2 more | 5 Ubuntu Linux, Fedora, Leap and 2 more | 2024-08-04 | 6.7 Medium |
| An integer overflow leading to a heap-buffer overflow was found in The X Input Method (XIM) client was implemented in libX11 before version 1.6.10. As per upstream this is security relevant when setuid programs call XIM client functions while running with elevated privileges. No such programs are shipped with Red Hat Enterprise Linux. | ||||
| CVE-2020-14314 | 5 Canonical, Debian, Linux and 2 more | 6 Ubuntu Linux, Debian Linux, Linux Kernel and 3 more | 2024-08-04 | 5.5 Medium |
| A memory out-of-bounds read flaw was found in the Linux kernel before 5.9-rc2 with the ext3/ext4 file system, in the way it accesses a directory with broken indexing. This flaw allows a local user to crash the system if the directory exists. The highest threat from this vulnerability is to system availability. | ||||
| CVE-2020-14310 | 4 Canonical, Gnu, Opensuse and 1 more | 11 Ubuntu Linux, Grub2, Leap and 8 more | 2024-08-04 | 5.7 Medium |
| There is an issue on grub2 before version 2.06 at function read_section_as_string(). It expects a font name to be at max UINT32_MAX - 1 length in bytes but it doesn't verify it before proceed with buffer allocation to read the value from the font value. An attacker may leverage that by crafting a malicious font file which has a name with UINT32_MAX, leading to read_section_as_string() to an arithmetic overflow, zero-sized allocation and further heap-based buffer overflow. | ||||
| CVE-2020-14311 | 4 Canonical, Gnu, Opensuse and 1 more | 11 Ubuntu Linux, Grub2, Leap and 8 more | 2024-08-04 | 5.7 Medium |
| There is an issue with grub2 before version 2.06 while handling symlink on ext filesystems. A filesystem containing a symbolic link with an inode size of UINT32_MAX causes an arithmetic overflow leading to a zero-sized memory allocation with subsequent heap-based buffer overflow. | ||||
| CVE-2020-14303 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2024-08-04 | 7.5 High |
