CVE-2020-14385 4 Canonical, Debian, Linux and 1 more 7 Ubuntu Linux, Debian Linux, Linux Kernel and 4 more 2024-11-21 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 5 Ubuntu Linux, Cryptsetup, Fedora and 2 more 2024-11-21 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-2020-14372 4 Fedoraproject, Gnu, Netapp and 1 more 13 Fedora, Grub2, Cloud Backup and 10 more 2024-11-21 7.5 High
A flaw was found in grub2 in versions prior to 2.06, where it incorrectly enables the usage of the ACPI command when Secure Boot is enabled. This flaw allows an attacker with privileged access to craft a Secondary System Description Table (SSDT) containing code to overwrite the Linux kernel lockdown variable content directly into memory. The table is further loaded and executed by the kernel, defeating its Secure Boot lockdown and allowing the attacker to load unsigned code. The highest threat from this vulnerability is to data confidentiality and integrity, as well as system availability.
CVE-2020-14364 6 Canonical, Debian, Fedoraproject and 3 more 14 Ubuntu Linux, Debian Linux, Fedora and 11 more 2024-11-21 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-2020-14355 5 Canonical, Debian, Opensuse and 2 more 12 Ubuntu Linux, Debian Linux, Leap and 9 more 2024-11-21 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-2020-14352 3 Fedoraproject, Opensuse, Redhat 7 Fedora, Backports Sle, Leap and 4 more 2024-11-21 8.0 High
A flaw was found in librepo in versions before 1.12.1. A directory traversal vulnerability was found where it failed to sanitize paths in remote repository metadata. An attacker controlling a remote repository may be able to copy files outside of the destination directory on the targeted system via path traversal. This flaw could potentially result in system compromise via the overwriting of critical system files. The highest threat from this flaw is to users that make use of untrusted third-party repositories.
CVE-2020-14351 3 Debian, Linux, Redhat 8 Debian Linux, Linux Kernel, Enterprise Linux and 5 more 2024-11-21 7.8 High
A flaw was found in the Linux kernel. A use-after-free memory flaw was found in the perf subsystem allowing a local attacker with permission to monitor perf events to corrupt memory and possibly escalate privileges. 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 2024-11-21 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-2020-14349 3 Opensuse, Postgresql, Redhat 7 Leap, Postgresql, Enterprise Linux and 4 more 2024-11-21 7.1 High
It was found that PostgreSQL versions before 12.4, before 11.9 and before 10.14 did not properly sanitize the search_path during logical replication. An authenticated attacker could use this flaw in an attack similar to CVE-2018-1058, in order to execute arbitrary SQL command in the context of the user used for replication.
CVE-2020-14311 4 Canonical, Gnu, Opensuse and 1 more 11 Ubuntu Linux, Grub2, Leap and 8 more 2024-11-21 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-2020-14310 4 Canonical, Gnu, Opensuse and 1 more 11 Ubuntu Linux, Grub2, Leap and 8 more 2024-11-21 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-2020-14309 3 Gnu, Opensuse, Redhat 7 Grub2, Leap, Enterprise Linux and 4 more 2024-11-21 6.7 Medium
There's an issue with grub2 in all versions before 2.06 when handling squashfs filesystems containing a symbolic link with name length of UINT32 bytes in size. The name size leads to an arithmetic overflow leading to a zero-size allocation further causing a heap-based buffer overflow with attacker controlled data.
CVE-2020-14308 3 Gnu, Opensuse, Redhat 7 Grub2, Leap, Enterprise Linux and 4 more 2024-11-21 6.4 Medium
In grub2 versions before 2.06 the grub memory allocator doesn't check for possible arithmetic overflows on the requested allocation size. This leads the function to return invalid memory allocations which can be further used to cause possible integrity, confidentiality and availability impacts during the boot process.
CVE-2020-13777 5 Canonical, Debian, Fedoraproject and 2 more 7 Ubuntu Linux, Debian Linux, Fedora and 4 more 2024-11-21 7.4 High
GnuTLS 3.6.x before 3.6.14 uses incorrect cryptography for encrypting a session ticket (a loss of confidentiality in TLS 1.2, and an authentication bypass in TLS 1.3). The earliest affected version is 3.6.4 (2018-09-24) because of an error in a 2018-09-18 commit. Until the first key rotation, the TLS server always uses wrong data in place of an encryption key derived from an application.
CVE-2020-13692 6 Debian, Fedoraproject, Netapp and 3 more 14 Debian Linux, Fedora, Steelstore Cloud Integrated Storage and 11 more 2024-11-21 7.7 High

CVE-2020-13398 5 Canonical, Debian, Freerdp and 2 more 7 Ubuntu Linux, Debian Linux, Freerdp and 4 more 2024-11-21 8.3 High
An issue was discovered in FreeRDP before 2.1.1. An out-of-bounds (OOB) write vulnerability has been detected in crypto_rsa_common in libfreerdp/crypto/crypto.c.
CVE-2020-13379 5 Fedoraproject, Grafana, Netapp and 2 more 11 Fedora, Grafana, E-series Performance Analyzer and 8 more 2024-11-21 8.2 High
The avatar feature in Grafana 3.0.1 through 7.0.1 has an SSRF Incorrect Access Control issue. This vulnerability allows any unauthenticated user/client to make Grafana send HTTP requests to any URL and return its result to the user/client. This can be used to gain information about the network that Grafana is running on. Furthermore, passing invalid URL objects could be used for DOS'ing Grafana via SegFault.
CVE-2020-13249 4 Fedoraproject, Mariadb, Opensuse and 1 more 7 Fedora, Connector\/c, Leap and 4 more 2024-11-21 8.8 High
libmariadb/mariadb_lib.c in MariaDB Connector/C before 3.1.8 does not properly validate the content of an OK packet received from a server. NOTE: although mariadb_lib.c was originally based on code shipped for MySQL, this issue does not affect any MySQL components supported by Oracle.
CVE-2020-13112 5 Canonical, Debian, Libexif Project and 2 more 7 Ubuntu Linux, Debian Linux, Libexif and 4 more 2024-11-21 9.1 Critical
