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 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 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.
