CVE-2025-44905 [HIGH] CWE-122 hdf5: Heap Buffer Overflow in HDF5 Scale-Offset Filter
hdf5: Heap Buffer Overflow in HDF5 Scale-Offset Filter
hdf5 v1.14.6 was discovered to contain a heap buffer overflow via the H5Z__filter_scaleoffset function.
A flaw was found in the HDF5 library, specifically in the H5Z__filter_scaleoffset function. This vulnerability allows memory corruption and application crashes via decompression of a malformed HDF5 file using the Scale-Offset filter. The issue arises when the function reads 1 byte beyond a 1-byte heap allocation, resulting in a heap-based buffer overflow.
Mitigation: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.

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.
