id summary reporter owner description type status priority milestone component version severity resolution keywords cc 4104 IReadBlock / IWriteBlock fail to seek lucasvr warmerdam "The SAGA Raster module may fail to seek to certain file offsets depending on the input file size. The computation of the offset performed in SAGARasterBand::{IReadBlock,IWriteBlock} on n_mBits, nRasterXSize, nRasterYSize and nBlockYOff results in a signed 32-bit temporary value. As a consequence, if the resulting offset is not within the 32-bit range, a truncated or potentially negative value could be provided to VSIFSeekL(), causing runtime errors such as: ERROR 3: Unable to seek to beginning of grid row. ERROR 1: IReadBlock failed at X offset 0, Y offset 6684 ERROR 3: Unable to seek to beginning of grid row. ERROR 1: IReadBlock failed at X offset 0, Y offset 6685 ERROR 3: Unable to seek to beginning of grid row.
