[Zlib-devel] zlibwapi - unzGetCurrentFileInfo BUG (NULL pointer write access fail)

[Hiroshi Kuno]

Hi, Gilles.

I found a backward imcompatible bug in unzGetCurrentFileInfo().

> unzGetCurrentFileInfo(unzip, /*fileinfo*/NULL, name, sizeof(name), /*extra*/NULL, 0, /*comment*/NULL, 0); // I need a entry name only.

That code occur "NULL pointer write accress fail" in zlibwapi v1.2.4.
But that code run successfully in zlibwapi v1.2.3.

We allowed that unzGetCurrentFileInfo()'s 2nd parameter "pfile_info" is NULL in v1.2.3.
