Risk: Medium
Local: No
Remote: Yes

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.
