HDF5 contains a NULL pointer dereference vulnerability. Processing a crafted HDF5 file containing an attribute with an invalid variable-length datatype type field may cause the application to crash when the attribute is read.

A double free vulnerability was discovered in the HDF5 library. Processing a crafted HDF5 file containing an oversized chunk size field via h5repack may cause the application to abort due to a double free.

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 nummessages count exceeding listmax, triggering out-of-bounds heap reads and writes in H5SMcachelistdeserialize and H5SMcachelistverifychksum.

Buffer underflow in H5Igetname /H5Ggetname if size is zero

Array full size, element count, and element size are not checked to make sure they match in H5Odtype.c

HDF5 is software for managing data. In 1.14.1-2 and earlier, an attacker who can control an h5 file parsed by HDF5 can trigger a write-based heap buffer overflow condition in the H5Trefmemsetnull method. This can lead to a denial-of-service condition, and potentially further issues such as remote code execution depending on the practical exploitability of the heap overflow against modern operating systems.

HDF5 is software for managing data. In 1.14.1-2 and earlier, a heap-use-after-free was found in the h5dump helper utility. An attacker who can supply a malicious h5 file can trigger a heap use-after-free. The freed object is referenced in a memmove call from H5Tconvstruct. The original object was allocated by H5Dtypeinfoinitphase3 and freed by H5Dtypeinfoterm.

HDF5 is software for managing data. Prior to version 1.14.4-2, an attacker who can control an h5 file parsed by HDF5 can trigger a write-based heap buffer overflow condition. This can lead to a denial-of-service condition, and potentially further issues such as remote code execution depending on the practical exploitability of the heap overflow against modern operating systems. Real-world exploitability of this issue in terms of remote-code execution is currently unknown. Version 1.14.4-2 fixes the issue.
