Red Hat Security Advisory 2022-5236-01

Dell VxRail, versions prior to 7.0.410, contain a Container Escape Vulnerability. A local high-privileged attacker could potentially exploit this vulnerability, leading to the execution of arbitrary OS commands on the container's underlying OS. Exploitation may lead to a system take over by an attacker.

Ubuntu Security Notice 5654-1 - It was discovered that the framebuffer driver on the Linux kernel did not verify size limits when changing font or screen size, leading to an out-of- bounds write. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Moshe Kol, Amit Klein and Yossi Gilad discovered that the IP implementation in the Linux kernel did not provide sufficient randomization when calculating port offsets. An attacker could possibly use this to expose sensitive information.

An update for kernel is now available for Red Hat Enterprise Linux 7.7 Advanced Update Support, Red Hat Enterprise Linux 7.7 Telco Extended Update Support, and Red Hat Enterprise Linux 7.7 Update Services for SAP Solutions. Red Hat Product Security has rated this update as having a security impact of Important.
