#3730 closed defect (fixed)

segmentation fault in gdalinfo because of hard coded array length in hdf5dataset.

Priority: normal Milestone:
Component: GDAL_Raster Version: unspecified
Severity: normal Keywords: hdf5

Description

gdalinfo was core dumping in method HDF5AttrIterate on some hdf5 data we have. The value of nAttrSize was greater than the hard coded array length of 8192. I changed the array size to be dynamic and it seems to be working now on my small sample of two data sets.

I added some code to look for overflows in arrays. Fixed in trunk (r20437), 1.7 branch (r20438) and 1.6 branch (r20439).
