A flaw was found in cri-o. A malicious container can create a symbolic link to arbitrary files on the host via directory traversal (“../“). This flaw allows the container to read and write to arbitrary files on the host system.

A flaw was found in OpenShift's Telemeter. If certain conditions are in place, an attacker can use a forged token to bypass the issue ("iss") check during JSON web token (JWT) authentication.

A flaw was found in Open vSwitch that allows ICMPv6 Neighbor Advertisement packets between virtual machines to bypass OpenFlow rules. This issue may allow a local attacker to create specially crafted packets with a modified or spoofed target IP address field that can redirect ICMPv6 traffic to arbitrary IP addresses.

A flaw was found in OpenShift API, as admission checks do not enforce "custom-host" permissions. This issue could allow an attacker to violate the boundaries, as permissions will not be applied.

A content spoofing flaw was found in OpenShift's OAuth endpoint. This flaw allows a remote, unauthenticated attacker to inject text into a webpage, enabling the obfuscation of a phishing operation.

A flaw was found in Open Virtual Network where the service monitor MAC does not properly rate limit. This issue could allow an attacker to cause a denial of service, including on deployments with CoPP enabled and properly configured.

A flaw was found in the `/v2/_catalog` endpoint in distribution/distribution, which accepts a parameter to control the maximum number of records returned (query string: `n`). This vulnerability allows a malicious user to submit an unreasonably large value for `n,` causing the allocation of a massive string array, possibly causing a denial of service through excessive use of memory.

A flaw was found in openvswitch (OVS). When processing an IP packet with protocol 0, OVS will install the datapath flow without the action modifying the IP header. This issue results (for both kernel and userspace datapath) in installing a datapath flow matching all IP protocols (nw_proto is wildcarded) for this flow, but with an incorrect action, possibly causing incorrect handling of other IP packets with a != 0 IP protocol that matches this dp flow.

runc through 1.1.4 has Incorrect Access Control leading to Escalation of Privileges, related to libcontainer/rootfs_linux.go. To exploit this, an attacker must be able to spawn two containers with custom volume-mount configurations, and be able to run custom images. NOTE: this issue exists because of a CVE-2019-19921 regression.

A vulnerability was found in OpenShift OSIN. It has been classified as problematic. This affects the function ClientSecretMatches/CheckClientSecret. The manipulation of the argument secret leads to observable timing discrepancy. The name of the patch is 8612686d6dda34ae9ef6b5a974e4b7accb4fea29. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-216987.
