Yes it does.
And I guess I need to look at /opt/freeware/lib again - last time I looked that was still at zlib-1.2.4.
To answer your question (zlib is now at 1.2.11) there was an exchange about zlib on the png-mng maillist.
The original question:
Hi,
Recently I saw many security vulnerability fixes being done in zlib and are included in zlib version 1.2.11. When will zlib 1.2.11 be integrated with libpng?
Thanks and regards,
Anand
The reply:
zlib is a separate package. I tested 1.2.10 against I think every currently supported libpng version and my main development system (which is Gentoo) is currently running 1.2.11, which means that any tests I do are against 1.2.11. I haven't run a complete set yet, but I don't anticipate any problems with 1.2.11.
Upgrading to 1.2.11 is possible without recompilation of libpng or anything which uses it; this has been happening on my own system with every release. zlib releases are API and ABI backward compatible; you can upgrade, however you can't downgrade (zlib doesn't offer forward compatibility in general).
I have never tried any of the machine specific enhancements; I only run unmodified zlib. Building libpng with "make check" is probably a reasonable way of validating the basic functionality of a modified zlib, but any zlib client only uses a small fraction of the compression options and only presents a small fraction of the possible compressed streams to "inflate".
Thus - as zlib supports upgrades you should not have any issues.
Also, aixtools.zlib installation does not remove the file in /opt/freeware/lib. Instead it renames to link in /usr/lib (so it can be restored should you choose to remove aixtools.zlib) - and sets a new symbolic link to point at /opt/lib/libz.a
As the aixtools version has an archive member with the same name as the archive member in /opt/freeware/lib/libz.a new and old programs work as expected.

Note re: above.
rpm.rte is not (always) included in the normal SP updates - so mine is old. I know there is a newer version of rpm.rte, but I do not know if it also is supported on AIX 6.1. My packaging, unless otherwise noted: installs on AIX 5.3 TL7 and later.
