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 handling, specifically within the SWSDfldsrch function of the SWapi.c file. The vulnerability is triggered by an unsigned underflow in the quote-stripping process, which can be exploited to read an excessive amount of data from the stack, leading to a crash. This vulnerability requires local access to exploit.
Users are advised to upgrade to OSGeo GDAL version 3.13.0RC1, which addresses this vulnerability.
