A flaw was found in the decompression function of registry-support. This issue can be triggered if an unauthenticated remote attacker tricks a user into parsing a devfile which uses the parent or plugin keywords. This could download a malicious archive and cause the cleanup process to overwrite or delete files outside of the archive, which should not be allowed.

A flaw was found in Corosync. A remote unauthenticated attacker can exploit a wrong return value vulnerability in the Corosync membership commit token sanity check by sending a specially crafted User Datagram Protocol (UDP) packet. This can lead to an out-of-bounds read, causing a denial of service (DoS) and potentially disclosing limited memory contents

A vulnerability was found in all openshift/mediawiki 4.x.x versions prior to 4.3.0, where an insecure modification vulnerability in the /etc/passwd file was found in the openshift/mediawiki. An attacker with access to the container could use this flaw to modify /etc/passwd and escalate their privileges.

A flaw was found in Corosync. An integer overflow vulnerability in Corosync's join message sanity validation allows a remote, unauthenticated attacker to send crafted User Datagram Protocol (UDP) packets. This can cause the service to crash, leading to a denial of service. This vulnerability specifically affects Corosync deployments configured to use totemudp/totemudpu mode.

A vulnerability was found in all openshift/postgresql-apb 4.x.x versions prior to 4.3.0, where an insecure modification vulnerability in the /etc/passwd file was found in the container openshift/postgresql-apb. An attacker with access to the container could use this flaw to modify /etc/passwd and escalate their privileges.

A flaw was found in grub2. The calculation of the translation buffer when reading a language .mo file in grubgettextgetstrfromposition() may overflow, leading to a Out-of-bound write. This issue can be leveraged by an attacker to overwrite grub2's sensitive heap data, eventually leading to the circumvention of secure boot protections.

A flaw was found in glib. This vulnerability allows a heap buffer overflow and denial-of-service (DoS) via an integer overflow in GLib's GIO (GLib Input/Output) escapebytestring() function when processing malicious file or remote filesystem attribute values.

A content spoofing vulnerability was found in the openshift/console 3.11 and 4.x. This flaw allows an attacker to craft a URL and inject arbitrary text onto the error page that appears to be from the OpenShift instance. This attack could potentially convince a user that the inserted text is legitimate.
