#938 closed defect (fixed)

HFA Compression code does not malloc enough space

Reported by: sam.gillingham@… Owned by: warmerdam
Priority: high Milestone:
Component: GDAL_Raster Version: unspecified
Severity: major Keywords:

Description 

Both m_pCounts and m_pValues areas should be allocated at least the size 
of a GUInt32 larger that they currently are to allow for the addition 
of an extra compressed value before the loop exits. Otherwise code overwrites
beyond the allocated space.
