Openshift Container Platform

In the Linux kernel through 4.19, a use-after-free can occur due to a race condition between fanout_add from setsockopt and bind on an AF_PACKET socket. This issue exists because of the 15fe076edea787807a7cdc168df832544b58eba6 incomplete fix for a race condition. The code mishandles a certain multithreaded case involving a packet_do_bind unregister action followed by a packet_notifier register action. Later, packet_release operates on only one of the two applicable linked lists. The attacker can achieve Program Counter control.Show less

Kibana versions 5.3.0 to 6.4.1 had a cross-site scripting (XSS) vulnerability via the source field formatter that could allow an attacker to obtain sensitive information from or perform destructive actions on behalf of other Kibana users.Show less

An out of bound write can occur when patching an Openshift object using the 'oc patch' functionality in OpenShift Container Platform before 3.7. An attacker can use this flaw to cause a denial of service attack on the Openshift master api service which provides cluster management.Show less

In Artifex Ghostscript before 9.24, attackers able to supply crafted PostScript files to the builtin PDF14 converter could use a use-after-free in copydevice handling to crash the interpreter or possibly have unspecified other impact.Show less

NodeJS Tough-Cookie version 2.2.2 contains a Regular Expression Parsing vulnerability in HTTP request Cookie Header parsing that can result in Denial of Service. This attack appear to be exploitable via Custom HTTP header passed by client. This vulnerability appears to have been fixed in 2.3.0.Show less

In all versions of Node.js prior to 6.14.4, 8.11.4 and 10.9.0 when used with UCS-2 encoding (recognized by Node.js under the names `'ucs2'`, `'ucs-2'`, `'utf16le'` and `'utf-16le'`), `Buffer#write()` can be abused to write outside of the bounds of a single `Buffer`. Writes that start from the second-to-last position of a buffer cause a miscalculation of the maximum length of the input bytes to be written.Show less

An input validation flaw was found in the way OpenShift 3 handles requests for images. A user, with a copy of the manifest associated with an image, can pull an image even if they do not have access to the image normally, resulting in the disclosure of any information contained within the image.Show less

A flaw was found in all Openshift Enterprise versions using the openshift elasticsearch plugin. An attacker with knowledge of the given name used to authenticate and access Elasticsearch can later access it without the token, bypassing authentication. This attack also requires that the Elasticsearch be configured with an external route, and the data accessed is limited to the indices.Show less

Poppler through 0.62 contains an out of bounds read vulnerability due to an incorrect memory access that is not mapped in its memory space, as demonstrated by pdfunite. This can result in memory corruption and denial of service. This may be exploitable when a victim opens a specially crafted PDF file.Show less

Ansible before versions 2.3.1.0 and 2.4.0.0 fails to properly mark lookup-plugin results as unsafe. If an attacker could control the results of lookup() calls, they could inject Unicode strings to be parsed by the jinja2 templating system, resulting in code execution. By default, the jinja2 templating language is now marked as 'unsafe' and is not evaluated.Show less

The OpenShift image import whitelist failed to enforce restrictions correctly when running commands such as "oc tag", for example. This could allow a user with access to OpenShift to run images from registries that should not be allowed.Show less

source-to-image component of Openshift Container Platform before versions atomic-openshift 3.7.53, atomic-openshift 3.9.31 is vulnerable to a privilege escalation which allows the assemble script to run as the root user in a non-privileged container. An attacker can use this flaw to open network connections, and possibly other actions, on the host which are normally only available to a root user.Show less

The Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, allows remote attackers to cause a denial of service (excessive memory allocation and application crash) via a crafted ELF file, as demonstrated by _bfd_elf_parse_attributes in elf-attrs.c and bfd_malloc in libbfd.c. This can occur during execution of nm.Show less

openshift-ansible before versions 3.9.23, 3.7.46 deploys a misconfigured etcd file that causes the SSL client certificate authentication to be disabled. Quotations around the values of ETCD_CLIENT_CERT_AUTH and ETCD_PEER_CLIENT_CERT_AUTH in etcd.conf result in etcd being configured to allow remote users to connect without any authentication if they can access the etcd server bound to the network on the master nodes. An attacker could use this flaw to read and modify all the data about the Openshift cluster in the etcd datastore, potentially adding another compute node, or bringing down the entire cluster.Show less

routing before version 3.10 is vulnerable to an improper input validation of the Openshift Routing configuration which can cause an entire shard to be brought down. A malicious user can use this vulnerability to cause a Denial of Service attack for other users of the router shard.Show less
