1, Infinite loop in MS-ZIP and Quantum decoders (minor issue):

A deficiency has been reported in the way cabextract extracted
certain Cabinet (*.cab) files, using the MZ-ZIP and Quantum decompressors.
If a local user was tricked into opening a specially-crafted *.cab
file, it could lead to infinite loop.
