Celestia Forums

I've seen that zlib.dll is version 1.1.3 and libpng1.dll is version 1.0.9 in the latest version of celestia

Should we or you update that lib ?
the latest version of zlib package is 1.1.4
http://www.gzip.org/zlib
the latest version of libpng is 1.2.4
http://sourceforge.net/project/showfile ... up_id=5624

Ill wait to hear from Chris, as to weather this might cause problems,
before I replace the Lib's.

What would be the advantage of these updated versions anyway

zlib v1.1.4 fixes a security bug in 1.1.3: some compressed data will cause it to crash the program calling it. This can cause problems on multi-user systems. See the zlib home page for details. They urge relinking the applicaion program against the new library. http://www.gzip.org/zlib/

libpng uses zlib. The newer versions of libpng also have quite a few patches to improve reading of marginally compliant png files.

Simply replacing the dlls *should* work (that's one of the reasons for making them dynamically loadable), but I'd rather wait for Chris to rebuild Celestia with the new versions.
