A flaw was found in grub2 in versions prior to 2.06. Setparam_prefix() in the menu rendering code performs a length calculation on the assumption that expressing a quoted single quote will require 3 characters, while it actually requires 4 characters which allows an attacker to corrupt memory by one byte for each quote in the input. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2021-20179 3 Dogtagpki, Fedoraproject, Redhat 5 Dogtagpki, Fedora, Certificate System and 2 more 2024-08-03 8.1 High
A flaw was found in pki-core. An attacker who has successfully compromised a key could use this flaw to renew the corresponding certificate over and over again, as long as it is not explicitly revoked. The highest threat from this vulnerability is to data confidentiality and integrity.
CVE-2021-20196 3 Debian, Qemu, Redhat 4 Debian Linux, Qemu, Advanced Virtualization and 1 more 2024-08-03 6.5 Medium
A NULL pointer dereference flaw was found in the floppy disk emulator of QEMU. This issue occurs while processing read/write ioport commands if the selected floppy drive is not initialized with a block device. This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability.
CVE-2021-20221 3 Debian, Qemu, Redhat 4 Debian Linux, Qemu, Advanced Virtualization and 1 more 2024-08-03 6.0 Medium
An out-of-bounds heap buffer access issue was found in the ARM Generic Interrupt Controller emulator of QEMU up to and including qemu 4.2.0on aarch64 platform. The issue occurs because while writing an interrupt ID to the controller memory area, it is not masked to be 4 bits wide. It may lead to the said issue while updating controller state fields and their subsequent processing. A privileged guest user may use this flaw to crash the QEMU process on the host resulting in DoS scenario.
CVE-2021-20201 2 Redhat, Spice Project 2 Enterprise Linux, Spice 2024-08-03 5.3 Medium
A flaw was found in spice in versions before 0.14.92. A DoS tool might make it easier for remote attackers to cause a denial of service (CPU consumption) by performing many renegotiations within a single connection.
CVE-2021-20225 4 Fedoraproject, Gnu, Netapp and 1 more 12 Fedora, Grub2, Ontap Select Deploy Administration Utility and 9 more 2024-08-03 6.7 Medium
A flaw was found in grub2 in versions prior to 2.06.

CVE-2021-20188 2 Podman Project, Redhat 5 Podman, Enterprise Linux, Openshift Container Platform and 2 more 2024-08-03 7.0 High
A flaw was found in podman before 1.7.0. File permissions for non-root users running in a privileged container are not correctly checked. This flaw can be abused by a low-privileged user inside the container to access any other file in the container, even if owned by the root user inside the container. It does not allow to directly escape the container, though being a privileged container means that a lot of security features are disabled when running the container. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2021-20230 2 Redhat, Stunnel 3 Enterprise Linux, Rhel Eus, Stunnel 2024-08-03 7.5 High
A flaw was found in stunnel before 5.57, where it improperly validates client certificates when it is configured to use both redirect and verifyChain options. This flaw allows an attacker with a certificate signed by a Certificate Authority, which is not the one accepted by the stunnel server, to access the tunneled service instead of being redirected to the address specified in the redirect option. The highest threat from this vulnerability is to confidentiality.
CVE-2021-20194 2 Linux, Redhat 3 Linux Kernel, Enterprise Linux, Openshift Container Platform 2024-08-03 7.8 High
