CVE-2020-1711 4 Debian, Opensuse, Qemu and 1 more 5 Debian Linux, Leap, Qemu and 2 more 2023-11-07 6.0 MEDIUM 6.0 MEDIUM
An out-of-bounds heap buffer access flaw was found in the way the iSCSI Block driver in QEMU versions 2.12.0 before 4.2.1 handled a response coming from an iSCSI server while checking the status of a Logical Address Block (LBA) in an iscsi_co_block_status() routine. A remote user could use this flaw to crash the QEMU process, resulting in a denial of service or potential execution of arbitrary code with privileges of the QEMU process on the host.
CVE-2020-14394 3 Fedoraproject, Qemu, Redhat 5 Extra Packages For Enterprise Linux, Fedora, Qemu and 2 more 2023-11-07 N/A 3.2 LOW
An infinite loop flaw was found in the USB xHCI controller emulation of QEMU while computing the length of the Transfer Request Block (TRB) Ring. This flaw allows a privileged guest user to hang the QEMU process on the host, resulting in a denial of service.
CVE-2020-14382 4 Canonical, Cryptsetup Project, Fedoraproject and 1 more 4 Ubuntu Linux, Cryptsetup, Fedora and 1 more 2023-11-07 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-2020-14373 2 Artifex, Redhat 2 Ghostscript, Enterprise Linux 2023-11-07 2.1 LOW 5.5 MEDIUM
A use after free was found in igc_reloc_struct_ptr() of psi/igc.c of ghostscript-9.25. A local attacker could supply a specially crafted PDF file to cause a denial of service.
CVE-2020-14372 4 Fedoraproject, Gnu, Netapp and 1 more 9 Fedora, Grub2, Cloud Backup and 6 more 2023-11-07 6.2 MEDIUM 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-2020-14370 3 Fedoraproject, Podman Project, Redhat 4 Fedora, Podman, Enterprise Linux and 1 more 2023-11-07 4.0 MEDIUM 5.3 MEDIUM
An information disclosure vulnerability was found in containers/podman in versions before 2.0.5. When using the deprecated Varlink API or the Docker-compatible REST API, if multiple containers are created in a short duration, the environment variables from the first container will get leaked into subsequent containers. An attacker who has control over the subsequent containers could use this flaw to gain access to sensitive information stored in such variables.
CVE-2020-14364 6 Canonical, Debian, Fedoraproject and 3 more 7 Ubuntu Linux, Debian Linux, Fedora and 4 more 2023-11-07 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-2020-14311 4 Canonical, Gnu, Opensuse and 1 more 7 Ubuntu Linux, Grub2, Leap and 4 more 2023-11-07 3.6 LOW 6.0 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 7 Ubuntu Linux, Grub2, Leap and 4 more 2023-11-07 3.6 LOW 6.0 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-2020-12458 3 Fedoraproject, Grafana, Redhat 4 Fedora, Grafana, Ceph Storage and 1 more 2023-11-07 2.1 LOW 5.5 MEDIUM
An information-disclosure flaw was found in Grafana through 6.7.3. The database directory /var/lib/grafana and database file /var/lib/grafana/grafana.db are world readable. This can result in exposure of sensitive information (e.g., cleartext or encrypted datasource passwords).
CVE-2020-10772 2 Nlnetlabs, Redhat 2 Unbound, Enterprise Linux 2023-11-07 5.0 MEDIUM 7.5 HIGH
An incomplete fix for CVE-2020-12662 was shipped for Unbound in Red Hat Enterprise Linux 7, as part of erratum RHSA-2020:2414. Vulnerable versions of Unbound could still amplify an incoming query into a large number of queries directed to a target, even with a lower amplification ratio compared to versions of Unbound that shipped before the mentioned erratum. This issue is about the incomplete fix for CVE-2020-12662, and it does not affect upstream versions of Unbound.
CVE-2020-10761 4 Canonical, Opensuse, Qemu and 1 more 4 Ubuntu Linux, Leap, Qemu and 1 more 2023-11-07 4.0 MEDIUM 5.0 MEDIUM
An assertion failure issue was found in the Network Block Device(NBD) Server in all QEMU versions before QEMU 5.0.1. This flaw occurs when an nbd-client sends a spec-compliant request that is near the boundary of maximum permitted request length. A remote nbd-client could use this flaw to crash the qemu-nbd server resulting in a denial of service.
CVE-2020-10756 5 Canonical, Debian, Libslirp Project and 2 more 6 Ubuntu Linux, Debian Linux, Libslirp and 3 more 2023-11-07 2.1 LOW 6.5 MEDIUM
An out-of-bounds read vulnerability was found in the SLiRP networking implementation of the QEMU emulator. This flaw occurs in the icmp6_send_echoreply() routine while replying to an ICMP echo request, also known as ping. This flaw allows a malicious guest to leak the contents of the host memory, resulting in possible information disclosure. This flaw affects versions of libslirp before 4.3.1.
CVE-2020-10749 3 Fedoraproject, Linuxfoundation, Redhat 4 Fedora, Cni Network Plugins, Enterprise Linux and 1 more 2023-11-07 6.0 MEDIUM 6.0 MEDIUM
A vulnerability was found in all versions of containernetworking/plugins before version 0.8.6, that allows malicious containers in Kubernetes clusters to perform man-in-the-middle (MitM) attacks. A malicious container can exploit this flaw by sending rogue IPv6 router advertisements to the host or other containers, to redirect traffic to the malicious container.
CVE-2020-10719 2 Netapp, Redhat 9 Active Iq Unified Manager, Oncommand Insight, Oncommand Workflow Automation and 6 more 2023-11-07 6.4 MEDIUM 6.5 MEDIUM
A flaw was found in Undertow in versions before 2.1.1.Final, regarding the processing of invalid HTTP requests with large chunk sizes. This flaw allows an attacker to take advantage of HTTP request smuggling.
CVE-2020-10711 5 Canonical, Debian, Linux and 2 more 11 Ubuntu Linux, Debian Linux, Linux Kernel and 8 more 2023-11-07 4.3 MEDIUM 5.9 MEDIUM
A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem in versions before 5.7. This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. While processing the CIPSO restricted bitmap tag in the 'cipso_v4_parsetag_rbm' routine, it sets the security attribute to indicate that the category bitmap is present, even if it has not been allocated. This issue leads to a NULL pointer dereference issue while importing the same category bitmap into SELinux. This flaw allows a remote network user to crash the system kernel, resulting in a denial of service.
CVE-2020-10696 2 Buildah Project, Redhat 3 Buildah, Enterprise Linux, Openshift Container Platform 2023-11-07 9.3 HIGH 8.8 HIGH
A path traversal flaw was found in Buildah in versions before 1.14.5. This flaw allows an attacker to trick a user into building a malicious container image hosted on an HTTP(s) server and then write files to the user's system anywhere that the user has permissions.
CVE-2020-10693 4 Ibm, Oracle, Quarkus and 1 more 8 Websphere Application Server, Weblogic Server, Quarkus and 5 more 2023-11-07 5.0 MEDIUM 5.3 MEDIUM
A flaw was found in Hibernate Validator version 6.1.2.Final. A bug in the message interpolation processor enables invalid EL expressions to be evaluated as if they were valid. This flaw allows attackers to bypass input sanitation (escaping, stripping) controls that developers may have put in place when handling user-controlled data in error messages.
CVE-2020-10690 6 Canonical, Debian, Linux and 3 more 33 Ubuntu Linux, Debian Linux, Linux Kernel and 30 more 2023-11-07 4.4 MEDIUM 6.4 MEDIUM
There is a use-after-free in kernel versions before 5.5 due to a race condition between the release of ptp_clock and cdev while resource deallocation. When a (high privileged) process allocates a ptp device file (like /dev/ptpX) and voluntarily goes to sleep. During this time if the underlying device is removed, it can cause an exploitable condition as the process wakes up to terminate and clean all attached files. The system crashes due to the cdev structure being invalid (as already freed) which is pointed to by the inode.
CVE-2020-10687 1 Redhat 4 Enterprise Linux, Jboss Enterprise Application Platform, Single Sign-on and 1 more 2023-11-07 5.8 MEDIUM 4.8 MEDIUM
A flaw was discovered in all versions of Undertow before Undertow 2.2.0.Final, where HTTP request smuggling related to CVE-2017-2666 is possible against HTTP/1.x and HTTP/2 due to permitting invalid characters in an HTTP request. This flaw allows an attacker to poison a web-cache, perform an XSS attack, or obtain sensitive information from request other than their own.
