hdf5: HDF5 Heap Buffer Overflow
vendor_redhat·2025-06-27·CVSS 4.8
CVE-2025-6750 [MEDIUM] CWE-119 hdf5: HDF5 Heap Buffer Overflow
hdf5: HDF5 Heap Buffer Overflow
A vulnerability, which was classified as problematic, has been found in HDF5 1.14.6. Affected by this issue is the function H5O__mtime_new_encode of the file src/H5Omtime.c. 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.
A flaw was found in hdf5. The H5O__mtime_new_encode function in src/H5Omtime.c contains a heap-based buffer overflow vulnerability that can be triggered by crafted input. A local attacker can exploit this condition by providing a specially constructed file. This manipulation may result in a denial of service.
Statement: The assigned severity is Low because the attack vector is local. An attacker would require local access to the system

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
