Title
HDF5 SOHM List Index Heap Buffer Overflow
Summary
Heap-based buffer overflow in the SOHM list-index deserialization code in HDF5 through 2.1.1 on all platforms allows attackers to cause a denial of service (crash) via a crafted HDF5 file whose shared-message list index declares a num_messages count exceeding list_max, triggering out-of-bounds heap reads and writes in H5SM__cache_list_deserialize and H5SM__cache_list_verify_chksum.

Title
HDF5 SOHM List Index Heap Buffer Overflow
Summary
Heap-based buffer overflow in the SOHM list-index deserialization code in HDF5 through 2.1.1 on all platforms allows attackers to cause a denial of service (crash) via a crafted HDF5 file whose shared-message list index declares a num_messages count exceeding list_max, triggering out-of-bounds heap reads and writes in H5SM__cache_list_deserialize and H5SM__cache_list_verify_chksum.

VAR-202506-1204
Vulnerability from variot - Updated: 2025-08-17 23:25A vulnerability has been found in HDF5 up to 1.14.6 and classified as critical. This vulnerability affects the function H5F_addr_decode_len of the file /hdf5/src/H5Fint.c. The manipulation leads to heap-based buffer overflow. An attack has to be approached locally. The exploit has been disclosed to the public and may be used. The HDF Group of HDF5 contains a buffer error vulnerability, a heap-based buffer overflow vulnerability, and an out-of-bounds write vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. HDF5 is an open-source library for HDF. An attacker could exploit this vulnerability to cause a denial of service
