HDF5 is a high-performance library and a file format specification that implements the HDF5 data model. If a file is corrupted such that an array datatype's size, the number of elements, and the element size are not in agreement it can trigger an out of bounds read. The array datatype stores the full size of the datatype (dt->shared->size) separately from the number of elements (dt->shared->u.array.nelem) and the element size (dt->shared->parent->shared->size). If any one of these are corrupted so that they don't align with the others (element size * nelem = full size), it can lead to an out of bounds read. Depending on what is corrupted, it can alter the type of out of bounds read triggered. The vulnerability is present only in files that have been maliciously altered, as its generally not possible to independently alter the full size of the datatype, the element count and the element size. As such, this is only present if a malicious actor is altering files, and won't appear in regular usage.
A flaw was found in HDF5, a high-performance library and file format specification. A remote attacker can exploit this vulnerability by providing a maliciously altered HDF5 file. If the file's array datatype has inconsistent size, element count, or element size, it can trigger an out-of-bounds read. This can lead to a denial of service (DoS) by causing the application to crash or become unresponsive.
Отчет
This Moderate flaw in HDF5 is due to an out-of-bounds read when processing a maliciously crafted HDF5 file with inconsistent array datatype metadata. Exploitation requires an attacker to provide a specially altered file, which can lead to a denial of service by crashing the application. Regular usage of HDF5 is not affected.
