Problem Description:
zlib through 1.2.12 has a heap-based buffer over-read or buffer
overflow in inflate in inflate.c via a large gzip header extra
field.
Impact:
Applications that call inflateGetHeader may be vulnerable to a
buffer overflow. Note that inflateGetHeader is not used by anything
in the FreeBSD base system, but may be used by third party
software.
