Overview

Affected versions of this package are vulnerable to Race Condition via the MSG driver. This driver looks for a matching "prologue"-file when calling MSGDataset::Open. The filename depends on the satellite number. There are only 4 satellites and all of them are tried until an existing prologue is found. The satellite number is stored as a static variable iCurrentSatellite and each call to Open triggers a loop that modifies this variable. If multiple threads try to open a MSG dataset, the state of iCurrentSatellite is modified in all threads.
