Red Hat Security Advisory 2022-5098-01

This is the third part of Vincent Danen’s “Patch management needs a revolution” series.Patch management needs a revolution, part 1: Surveying cybersecurity’s lineagePatch management needs a revolution, part 2: The flood of vulnerabilitiesVulnerability ratings are the foundation for a good risk-based vulnerability management program, especially if they’re from a trusted party. Recently I was discussing this topic with a customer and they said they practiced Zero Trust, as if to explain why they could not trust our ratings. The irony, however, is that they did use National Vulnerabilit

An issue exists in SoftIron HyperCloud where compute nodes may come online immediately without following the correct initialization process.  In this instance, workloads may be scheduled on these nodes and deploy to a failed or erroneous state, which impacts the availability of these workloads that may be deployed during this time window. This issue impacts HyperCloud versions from 2.0.0 to before 2.0.3.

Ubuntu Security Notice 6355-1 - Daniel Axtens discovered that specially crafted images could cause a heap-based out-of-bonds write. A local attacker could possibly use this to circumvent secure boot protections. Daniel Axtens discovered that specially crafted images could cause out-of-bonds read and write. A local attacker could possibly use this to circumvent secure boot protections. Daniel Axtens discovered that specially crafted images could cause buffer underwrite which allows arbitrary data to be written to a heap. A local attacker could possibly use this to circumvent secure boot protections.

Integer underflow in grub_net_recv_ip4_packets; A malicious crafted IP packet can lead to an integer underflow in grub_net_recv_ip4_packets() function on rsm->total_len value. Under certain circumstances the total_len value may end up wrapping around to a small integer number which will be used in memory allocation. If the attack succeeds in such way, subsequent operations can write past the end of the buffer.

Dell PowerStore versions prior to 3.5 contain an improper verification of cryptographic signature vulnerability. An attacker can trick a high privileged user to install a malicious binary by bypassing the existing cryptographic signature checks

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.

Dell EMC Metro node, Version(s) prior to 7.1, contain a Code Injection Vulnerability. An authenticated nonprivileged attacker could potentially exploit this vulnerability, leading to the execution of arbitrary OS commands on the application.

Hello everyone! Great news for my open source Scanvus project! You can now perform vulnerability checks on Linux hosts and docker images not only using the Vulners.com API, but also with the Vulns.io VM API. It’s especially nice that all the code to support the new API was written and contributed by colleagues from Vulns.io. […]

A heap out-of-bounds write may heppen during the handling of Huffman tables in the PNG reader. This may lead to data corruption in the heap space. Confidentiality, Integrity and Availablity impact may be considered Low as it's very complex to an attacker control the encoding and positioning of corrupted Huffman entries to achieve results such as arbitrary code execution and/or secure boot circumvention. This flaw affects grub2 versions prior grub-2.12.

A crafted JPEG image may lead the JPEG reader to underflow its data pointer, allowing user-controlled data to be written in heap. To a successful to be performed the attacker needs to perform some triage over the heap layout and craft an image with a malicious format and payload. This vulnerability can lead to data corruption and eventual code execution or secure boot circumvention. This flaw affects grub2 versions prior grub-2.12.
