CVE-2026-8086: Heap-based Buffer Overflow in OSGeo gdal
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.
AI Analysis
Technical Summary
This vulnerability in OSGeo gdal affects the SWnentries function in the HDF4 EOS API implementation, where manipulation of the DimensionName argument can cause a heap-based buffer overflow. The flaw exists in versions up to 3.13.0dev-4. Exploitation requires local privileges and no user interaction, with low complexity and low vector complexity. The vulnerability has a CVSS 4.8 (medium) score. A patch identified by commit 9491e794f1757f08063ea2f7a274ad2994afa636 is available in version 3.12.4RC1 to remediate this issue.
Potential Impact
Successful exploitation can lead to a heap-based buffer overflow, which may cause application crashes or potentially allow execution of arbitrary code with local privileges. The attack requires local access and does not involve user interaction, limiting remote exploitation. The medium CVSS score reflects moderate impact given the local attack vector and required privileges.
Mitigation Recommendations
Upgrade OSGeo gdal to version 3.12.4RC1 or later, which includes the patch (commit 9491e794f1757f08063ea2f7a274ad2994afa636) that fixes this heap-based buffer overflow vulnerability.
