Change #236833

Comments

zip: correctly handle PKZIP data descriptors
* unzip.c (DATSIG, L8): New macros.
(unzip): Previously only one of the four possible data descriptors was
handled. Check for all four when validating the uncompressed
data with the CRC and length in the data descriptor. This also now
checks the full eight-byte uncompressed length for zip files.
