Background
HDF5 is a widely used data model, library, and file format for storing and managing scientific data. It supports the creation and manipulation of complex data structures and is utilized in various fields such as engineering, physics, and bioinformatics. The HDF5 library is essential for applications that require efficient data storage and retrieval. However, versions of HDF5 up to 1.14.3 are vulnerable to a heap-based buffer overflow, which can lead to severe security issues.
Vulnerability Detail
The vulnerability identified as CVE-2024-33873 is a heap-based buffer overflow found in the H5D__scatter_mem function within the H5Dscatgath.c file of the HDF5 library. This flaw allows an attacker to exploit the memory management of the application, potentially leading to arbitrary code execution or application crashes. The vulnerability arises from improper handling of memory during data scattering operations, which can be triggered by specially crafted input data.
