DescriptionCVE.org

A vulnerability was determined in OSGeo gdal up to 3.13.0dev-4. This vulnerability affects the function memmove of the file frmts/hdf4/hdf-eos/SWapi.c of the component HDF-EOS Grid File Handler. This manipulation causes out-of-bounds read. The attack is restricted to local execution. The exploit has been publicly disclosed and may be utilized. Upgrading to version 3.13.0RC1 is able to resolve this issue. Patch name: a791f70f8eaec540974ec989ca6fb00266b7646c. Upgrading the affected component is advised.

AnalysisAI

Out-of-bounds read in OSGeo GDAL up to version 3.13.0dev-4 occurs in the HDF-EOS Grid File Handler when parsing malformed HDF4 files, allowing local authenticated attackers to read memory beyond buffer bounds. The vulnerability exists in the memmove operation within SWapi.c and GDapi.c that processes field information without proper bounds validation. Vendor-released patch available in version 3.13.0RC1; publicly available exploit code exists.

Technical ContextAI

GDAL (Geospatial Data Abstraction Library) is an open-source library for reading and writing raster and vector geospatial data formats. The vulnerability resides in the HDF-EOS (Hierarchical Data Format-Earth Observing System) Grid File Handler component, specifically in functions that parse field metadata from HDF4 files. The vulnerable code performs a memmove operation to strip parentheses from field name strings without validating string length, leading to CWE-125 (Out-of-bounds Read). When a malformed HDF4 file contains a field name string shorter than two characters (e.g., a single character or empty string), the memmove call with a negative or zero length parameter causes reads beyond the allocated buffer. The fix validates string length and checks for parentheses before performing the memory operation, preventing the out-of-bounds read.

RemediationAI

Upgrade GDAL to version 3.13.0RC1 or later, which includes patch a791f70f8eaec540974ec989ca6fb00266b7646c. If upgrading is not immediately feasible, restrict file processing to trusted HDF4 sources and disable HDF4 driver support in GDAL if not required (via compilation options or runtime driver filtering). Additionally, apply operating system-level access controls to limit which users can execute GDAL and supply input files, reducing the attack surface to privileged or system administrators. Monitor GDAL usage logs for attempts to process malformed HDF4 files. See https://github.com/OSGeo/gdal/releases/tag/v3.13.0RC1 for release notes and https://github.com/OSGeo/gdal/commit/a791f70f8eaec540974ec989ca6fb00266b7646c for technical details of the fix.
