Critical

Base vector

AV:N/AC:L/Au:N/C:C/I:C/A:C

Name of the Vulnerable Software and Affected Versions GDAL versions 3.0.1 and earlier

Description The issue is related to a double free in the OGRExpatRealloc function in the ogr/ogr expat.cpp file of the GDAL library, which occurs when the 10MB threshold is exceeded. This can allow a remote attacker to access confidential data, compromise its integrity, and cause a denial of service.

Recommendations For GDAL versions 3.0.1 and earlier, consider updating to a version that fixes the double free issue in the OGRExpatRealloc function. As a temporary workaround, consider restricting the use of the OGRExpatRealloc function in the ogr/ogr expat.cpp file to minimize the risk of exploitation.
