Description
A security flaw has been discovered in OSGeo gdal up to 3.13.0dev-4. Impacted is the function GDnentries of the file frmts/hdf4/hdf-eos/GDapi.c. Performing a manipulation of the argument DataFieldName results in heap-based buffer overflow. The attack must be initiated from a local position. The exploit has been released to the public and may be used for attacks. Upgrading to version 3.13.0RC1 is recommended to address this issue. The patch is named 184f77dbcc74118c062c05e464c88161d3c37b9b. You should upgrade the affected component.
A heap-based buffer overflow vulnerability has been identified in OSGeo GDAL versions through 3.13.0dev-4. This issue arises in the HDF4-EOS Grid API, specifically within the GDnentries function of GDapi.c. The vulnerability is triggered by unbounded string concatenation into a user-allocated buffer, which can lead to memory corruption. This flaw is particularly concerning as it allows for a potential overwrite of heap memory, which could be exploited to execute arbitrary code.
Users are advised to upgrade to OSGeo GDAL version 3.13.0RC1, where this vulnerability has been fixed.
