CVE ID | Published | Description | Score | Severity |
---|---|---|---|---|
A crafted JPEG image may lead the JPEG reader to underflow its data pointer, allowing user-controlled data to be written in heap. To a successful to be performed the attacker needs to perform some triage over the heap layout and craft an image with a malicious format and payload. This vulnerability can lead to data corruption and eventual code execution or secure boot circumvention. This flaw affects grub2 versions prior grub-2.12. | 7 |

A heap out-of-bounds write may heppen during the handling of Huffman tables in the PNG reader. This may lead to data corruption in the heap space. Confidentiality, Integrity and Availablity impact may be considered Low as it's very complex to an attacker control the encoding and positioning of corrupted Huffman entries to achieve results such as arbitrary code execution and/or secure boot circumvention. This flaw affects grub2 versions prior grub-2.12. | 4.5 |
Medium |
||
A crafted 16-bit grayscale PNG image may lead to a out-of-bounds write in the heap area. An attacker may take advantage of that to cause heap data corruption or eventually arbitrary code execution and circumvent secure boot protections. This issue has a high complexity to be exploited as an attacker needs to perform some triage over the heap layout to achieve signifcant results, also the values written into the memory are repeated three times in a row making difficult to produce valid payloads. This flaw affects grub2 versions prior grub-2.12. | 4.5 |

It was found in OpenShift, before version 4.8, that the generated certificate for the in-cluster Service CA, incorrectly included additional certificates. The Service CA is automatically mounted into all pods, allowing them to safely connect to trusted in-cluster services that present certificates signed by the trusted Service CA. The incorrect inclusion of additional CAs in this certificate would allow an attacker that compromises any of the additional CAs to masquerade as a trusted in-cluster service. | 4.6 |

An insecure modification flaw in the /etc/kubernetes/kubeconfig file was found in OpenShift. This flaw allows an attacker with access to a running container which mounts /etc/kubernetes or has local access to the node, to copy this kubeconfig file and attempt to add their own node to the OpenShift cluster. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. This flaw affects versions before openshift4/ose-machine-config-operator v4.7.0-202105111858.p0. | 7 |
High |
||
A flaw was found in the OpenShift web console, where the access token is stored in the browser's local storage. An attacker can use this flaw to get the access token via physical access, or an XSS attack on the victim's browser. This flaw affects openshift/console versions before openshift/console-4. | 6.1 |
Medium |
||
An insecure modification vulnerability in the /etc/passwd file was found in the container openshift/apb-base, affecting versions before the following 4.3.5, 4.2.21, 4.1.37, and 3.11.188-4. An attacker with access to the container could use this flaw to modify /etc/passwd and escalate their privileges. | 7 |
High |
||
An insecure modification vulnerability in the /etc/passwd file was found in the container openshift/mariadb-apb, affecting versions before the following 4.3.5, 4.2.21, 4.1.37, and 3.11.188-4 . An attacker with access to the container could use this flaw to modify /etc/passwd and escalate their privileges. | 7 |

||
In atomic-openshift before version 3.10.9 a malicious network-policy configuration can cause Openshift Routing to crash when using ovs-networkpolicy plugin. An attacker can use this flaw to cause a Denial of Service (DoS) attack on an Openshift 3.9, or 3.7 Cluster. | 7.5 |
