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.
A vulnerability in OSGeo GDAL versions up to 3.13.0dev-4 has been identified within the HDF-EOS Grid File Handler. The issue arises in the 'memmove' function of 'frmts/hdf4/hdf-eos/SWapi.c', where the code improperly handles metadata values. Specifically, the 'DimList' string is manipulated without adequate length checks, leading to a size_t underflow. This flaw allows for an out-of-bounds read, as the 'memmove' operation attempts to read an excessive amount of data, approximately 18 exabytes, causing a crash. The vulnerability requires local execution and has been publicly disclosed.
Users can upgrade to OSGeo GDAL version 3.13.0RC1 to address this vulnerability.
