Description

A correction fix is requested for :
CVE-2014-8139 unzip: CRC32 verification heap-based buffer overread (oCERT-2014-011)

The problem was an unrealistic/invalid value in a .ZIP Extra Field. There was
a check (in extract.c:TestExtraField()) for an extra-block length that was too
large, but no check for a too-small value. In this example, the length
(ebLen) was 1, and when "(ebLen-4)" was passed to crc32(), bad things
happened.
