Red Hat Security Advisory 2022-5098-01 - The grub2 packages provide version 2 of the Grand Unified Boot Loader, a highly configurable and customizable boot loader with modular architecture. The packages support a variety of kernel formats, file systems, computer architectures, and hardware devices. The shim package contains a first-stage UEFI boot loader that handles chaining to a trusted full boot loader under secure boot environments. Issues addressed include buffer overflow, out of bounds write, and use-after-free vulnerabilities.

Realtek USB driver has a buffer overflow vulnerability due to insufficient parameter length verification in the API function. An unauthenticated LAN attacker can exploit this vulnerability to disrupt services.

NHI’s health insurance web service component has insufficient validation for input string length, which can result in heap-based buffer overflow attack. A remote attacker can exploit this vulnerability to flood the memory space reserved for the program, in order to terminate service without authentication, which requires a system restart to recover service.

Red Hat Security Advisory 2022-5002-01 - The Advanced Virtualization module provides the user-space component for running virtual machines that use KVM in environments managed by Red Hat products. Issues addressed include buffer overflow, integer overflow, and memory leak vulnerabilities.

Heap-based Buffer Overflow in GitHub repository vim/vim prior to 8.2.

The PPM reader in libjpeg-turbo through 2.0.90 mishandles use of tjLoadImage for loading a 16-bit binary PPM file into a grayscale buffer and loading a 16-bit binary PGM file into an RGB buffer. This is related to a heap-based buffer overflow in the get_word_rgb_row function in rdppm.c.

A stack-based buffer overflow vulnerability exists in the BlynkConsole.h runCommand functionality of Blynk -Library v1.0.1. A specially-crafted network request can lead to command execution. An attacker can send a network request to trigger this vulnerability.
