CVE-2026-8086 Details
Description
A vulnerability was identified in OSGeo gdal up to 3.13.0dev-4. This issue affects the function SWnentries of the file frmts/hdf4/hdf-eos/SWapi.c. Such manipulation of the argument DimensionName leads to heap-based buffer overflow. The attack must be carried out locally. The exploit is publicly available and might be used. Upgrading to version 3.12.4RC1 is capable of addressing this issue. The name of the patch is 9491e794f1757f08063ea2f7a274ad2994afa636. It is advisable to upgrade the affected component.
A heap-based buffer overflow vulnerability has been identified in OSGeo GDAL versions through 3.13.0dev-4. The issue arises in the HDF4-EOS processing module, specifically within the 'SWnentries' function of 'frmts/hdf4/hdf-eos/SWapi.c'. The vulnerability is triggered by unbounded string concatenation into a caller-allocated buffer, based on incorrect assumptions about the formatting of metadata values. This flaw allows for local exploitation, potentially leading to arbitrary memory corruption.
Users are advised to upgrade to GDAL version 3.12.4RC1, which addresses this vulnerability.
