ChangeLog file for zlib
+Changes in 1.1.4 (11 March 2002)

+- Avoid accesses before window for invalid distances with inflate window
+ less than 32K.

+ of 256 bytes. (A complete fix will be available in 1.1.5).

-The changes made in version 1.1.2 are documented in the file ChangeLog.
-The main changes since 1.1.1 are:
-
-- added contrib/minzip, mini zip and unzip based on zlib (Gilles Vollant)
- See http://www.winimage.com/zLibDll/unzip.html
-- preinitialize the inflate tables for fixed codes, to make the code
- completely thread safe (Mark)
-- some simplifications and slight speed-up to the inflate code (Mark)
-- fix gzeof on non-compressed files (Allan Schrum)
-- add -std1 option in configure for OSF1 to fix gzprintf (Martin Mokrejs)
-- use default value of 4K for Z_BUFSIZE for 16-bit MSDOS (Tim Wegner + Glenn)
-- added os2/Makefile.def and os2/zlib.def (Andrew Zabolotny)
-- add shared lib support for UNIX_SV4.2MP (MATSUURA Takanori)
-- do not wrap extern "C" around system includes (Tom Lane)
-- added amiga/Makefile.pup for Amiga powerUP SAS/C PPC (Andreas Kleinert)
-- allow "make install prefix=..." even after configure (Glenn Randers-Pehrson)
-- allow "configure --prefix $HOME" (Tim Mooney)

+The changes made in version 1.1.4 are documented in the file ChangeLog.

+- ZFREE was repeated on same allocation on some error conditions.
+ This creates a security problem described in

+- force windowBits > 8 to avoid a bug in the encoder for a window size

+The beta version 1.1.5beta includes many more changes. A new official

- gzdopen is not supported on RISCOS, BEOS and by some Mac compilers.
