Tomas Hoger reports :

The compress/ LZW decompress implentation does not correctly handle
compressed streams that contain code words that were not yet added to
the decompression table. This may lead to arbitrary memory corruption.
Successfull exploitation may possible lead to a local privilege
escalation.
