HDF5 Library through 1.14.3 contains a heap-based buffer over-read in H5HLfldeserialize in H5HLcache.c resulting in the corruption of the instruction pointer a different vulnerability than CVE-2024-32613.

A vulnerability was found in HDF5 up to 1.14.6. It has been rated as critical. Affected by this issue is the function H5FLblkgclist of the file src/H5FL.c. The manipulation of the argument H5FLblkheadt leads to use after free. An attack has to be approached locally. The exploit has been disclosed to the public and may be used.

H5Zfilterfletcher32 in H5Zfletcher32.c in HDF5 through 2.3.0 computes the data length to checksum by subtracting the 4-byte trailing checksum size from the input buffer size without checking that the buffer is at least 4 bytes, allowing a sizet underflow. This allows attackers to cause a denial of service (massively out-of-bounds read and application crash in H5checksumfletcher32) via a crafted HDF5 file with a Fletcher32-filtered chunk smaller than 4 bytes, triggered via H5Dread, e.g. by the h5ls or h5dump tools.

The H5Znbitdecompressonebyte, H5Znbitdecompressonenooptype, and H5Znbitdecompressoneatomic functions in H5Znbit.c in HDF5 through 2.3.0 advance a read index into the compressed chunk buffer without bounding it against the buffer's actual size. This allows attackers to cause an out-of-bounds heap read, and in constrained cases disclosure of adjacent heap memory into decompressed dataset values, via a crafted HDF5 file whose N-Bit filter parameters describe more decompressed data than the stored compressed chunk actually contains, triggered via H5Dread, e.g. by the h5ls or h5repack tools.

A vulnerability, which was classified as problematic, was found in HDF5 1.14.6. Affected is the function H5FSsectlinksize of the file src/H5FSsection.c. The manipulation leads to heap-based buffer overflow. It is possible to launch the attack on the local host. The exploit has been disclosed to the public and may be used.

A vulnerability classified as problematic was found in HDF5 1.14.6. This vulnerability affects the function H5Ofsinfoencode of the file /src/H5Ofsinfo.c. The manipulation leads to heap-based buffer overflow. It is possible to launch the attack on the local host. The exploit has been disclosed to the public and may be used.

A vulnerability was found in HDF5 1.14.6 and classified as critical. This issue affects the function H5MMstrndup of the component Metadata Attribute Decoder. The manipulation leads to heap-based buffer overflow. Attacking locally is a requirement. The exploit has been disclosed to the public and may be used. The vendor plans to fix this issue in an upcoming release.

HDF5 Library through 1.14.3 has a SEGV in H5Tclosereal in H5T.c, resulting in a corrupted instruction pointer.

HDF5 Library through 1.14.3 contains a heap-based buffer over-read in the function H5HLfldeserialize in H5HLcache.c, a different vulnerability than CVE-2024-32612.
