Changelog for libpng15-15-1.5.13-3.4.i586.rpm :
Wed Oct 24 14:00:00 2012 jengelhAATTinai.de
- Add missing baselib requires for compat-devel-32bit

Thu Sep 27 14:00:00 2012 pgajdosAATTsuse.com
- updated to 1.5.13:
Do not compile PNG_DEPRECATED, PNG_ALLOC and PNG_PRIVATE when __GNUC__ < 3.
Removed references to png_zalloc() and png_zfree() from the manual.
Revised PNG_FP_EXPORT and PNG_FIXED_EXPORT macros to avoid generating
lone semicolons (patch ported from libpng-1.6.0beta11).
Corrected handling of the image array and the row_pointers array in example.
When png_set_filler is used to strip a filler channel during write, the
code prior to 1.5 would ignore the case where the output required an
alpha channel or when the output was a palettized PNG. In libpng-1.5 the
ignorance was lost and libpng proceeded to strip the channel resulting
in a bad (potential memory overwrite) failure later. This reverts
the behavior to the pre-1.5 state but issues a warning. libpng-1.6 is
expected to issue an error on the erroneous png_set_filler call.
Use png_memset() consistently (pngmem.c contained some bare \"memset\" calls).

Wed Jul 11 14:00:00 2012 pgajdosAATTsuse.com
- updated to 1.5.12:
Changed \"a+w\" to \"u+w\" in Makefile.in to fix CVE-2012-3386.

Fri Jun 15 14:00:00 2012 pgajdosAATTsuse.com
- updated to 1.5.11:
Enable png_set_check_for_invalid_index() for both read and write.
Made fixes for new optimization warnings from gcc 4.7.0. The compiler
performed an optimization which is safe but then warned about it.
Changing the type of \'palette_number\' in pngvalid.c removes the warning.
Improved efficiency of new do_check_palette_indexes() function.
Don\'t check palette indexes if num_palette is 0 (as it can be in MNG files).
Added two images to contrib/pngsuite (1-bit and 2-bit transparent grayscale),
and renamed three whose names were inconsistent with those in
pngsuite/README.txt.

Thu Mar 29 14:00:00 2012 pgajdosAATTsuse.com
- updated to 1.5.10:
Removed two useless #ifdef directives from pngread.c and one from pngrutil.c
Always put the CMAKE_LIBRARY in \"lib\" (removed special WIN32 case).
Removed empty vstudio/pngstest directory (Clifford Yapp).
Eliminated redundant png_push_read_tEXt|zTXt|iTXt|unknown code from
pngpread.c and use the sequential png_handle_tEXt, etc., in pngrutil.c;
now that png_ptr->buffer is inaccessible to applications, the special
handling is no longer useful.
Fixed bug with png_handle_hIST with odd chunk length (Frank Busse).
Added PNG_SAFE_LIMITS feature to pnglibconf.dfa and code in pngconf.h
to reset the user limits to safe ones if PNG_SAFE_LIMITS is defined.
To enable, use \"CPPFLAGS=-DPNG_SAFE_LIMITS_SUPPORTED\" on the configure
command or put \"#define PNG_SAFE_LIMITS_SUPPORTED\" in pnglibconf.h.
Revised the SAFE_LIMITS feature to be the same as the feature in libpng16.
Added information about the new limits in the manual.
Updated Makefile.in
Removed unused \"current_text\" members of png_struct and the png_free()
of png_ptr->current_text from pngread.c
Fixed PNG_LIBPNG_BUILD_BASE_TYPE definition.
Fixed CMF optimization of non-IDAT compressed chunks, which was added at
libpng-1.5.4. It sometimes produced too small of a window.
Reject all iCCP chunks after the first, even if the first one is invalid.
Added palette-index checking. Issue a png_benign_error() if an invalid
index is found.
Revised example.c to put text strings in a temporary character array
instead of directly assigning string constants to png_textp members.
This avoids compiler warnings when -Wwrite-strings is enabled.
Prevent PNG_EXPAND+PNG_SHIFT doing the shift twice.
Revised png_set_text_2() to avoid potential memory corruption (fixes
CVE-2011-3048).

Mon Feb 20 13:00:00 2012 pgajdosAATTsuse.com
- updated to 1.5.9:

* fixed CVE-2011-3026 [bnc#747311]

Thu Feb 2 13:00:00 2012 pgajdosAATTsuse.com
- updated to 1.5.8:
Fixed one-byte (stack) buffer-overrun bug in png_formatted_warning()
(CVE-2011-3464)

Mon Dec 19 13:00:00 2011 pgajdosAATTsuse.com
- updated to 1.5.7:
Added support for ARM processor (Mans Rullgard)
Fixed bug in pngvalid on early allocation failure; fixed type cast in
pngmem.c; pngvalid would attempt to call png_error() if the allocation
of a png_struct or png_info failed. This would probably have led to a
crash. The pngmem.c implementation of png_malloc() included a cast
to png_size_t which would fail on large allocations on 16-bit systems.
Fix for the preprocessor of the Intel C compiler. The preprocessor
splits adjacent AATT signs with a space; this changes the concatentation
token from AATT-AATT-AATT to PNG_JOIN; that should work with all compiler
preprocessors.
Paeth filter speed improvements from work by Siarhei Siamashka. This
changes the \'Paeth\' reconstruction function to improve the GCC code
generation on x86. The changes are only part of the suggested ones;
just the changes that definitely improve speed and remain simple.
The changes also slightly increase the clarity of the code.
Check compression_type parameter in png_get_iCCP and remove spurious
casts. The compression_type parameter is always assigned to, so must
be non-NULL. The cast of the profile length potentially truncated the
value unnecessarily on a 16-bit int system, so the cast of the (byte)
compression type to (int) is specified by ANSI-C anyway.
Fixed FP division by zero in pngvalid.c; the \'test_pixel\' code left
the sBIT fields in the test pixel as 0, which resulted in a floating
point division by zero which was irrelevant but causes systems where
FP exceptions cause a crash. Added code to pngvalid to turn on FP
exceptions if the appropriate glibc support is there to ensure this is
tested in the future.
Updated scripts/pnglibconf.mak and scripts/makefile.std to handle the
new PNG_JOIN macro.
Added versioning to pnglibconf.h comments.
Simplified read/write API initial version; basic read/write tested on
a variety of images, limited documentation (in the header file.)
Installed more accurate linear to sRGB conversion tables. The slightly
modified tables reduce the number of 16-bit values that
convert to an off-by-one 8-bit value. The \"makesRGB.c\" code that was used
to generate the tables is now in a contrib/sRGBtables sub-directory.
etc. see CHANGES

Thu Dec 1 13:00:00 2011 idoenmezAATTsuse.de
- Name field shouldn\'t contain a macro

Thu Dec 1 13:00:00 2011 cooloAATTsuse.com
- add libtool as buildrequire to avoid implicit dependency

Thu Nov 3 13:00:00 2011 pgajdosAATTsuse.com
- updated to 1.5.6:
Fixed some 64-bit type conversion warnings in pngrtran.c
Moved row_info from png_struct to a local variable.
The various interlace mask arrays have been made into arrays of
bytes and made PNG_CONST and static (previously some arrays were
marked PNG_CONST and some weren\'t).
Additional checks have been added to the transform code to validate the
pixel depths after the transforms on both read and write.
Removed some redundant code from pngwrite.c, in png_desgtroy_write_struct().
Changed chunk reading/writing code to use png_uint_32 instead of png_byte[4].
This removes the need to allocate temporary strings for chunk names on
the stack in the read/write code. Unknown chunk handling still uses the
string form because this is exposed in the API.
Added a note in the manual the png_read_update_info() must be called only
once with a particular info_ptr.
Revised test-pngtest.sh to report FAIL when pngtest fails.
Added \"--strict\" option to pngtest, to report FAIL when the failure is
only because the resulting valid files are different.
Revised CMakeLists.txt to work with mingw and removed some material from
CMakeLists.txt that is no longer useful in libpng-1.5.
Fixed typo in Makefile.in and Makefile.am (\"-M Wl\" should be \"-M -Wl\").\"
Speed up png_combine_row() for interlaced images. This reduces the generality
of the code, allowing it to be optimized for Adam7 interlace. The masks
passed to png_combine_row() are now generated internally, avoiding
some code duplication and localizing the interlace handling somewhat.
Align png_struct::row_buf - previously it was always unaligned, caused by
a bug in the code that attempted to align it; the code needs to subtract
one from the pointer to take account of the filter byte prepended to
each row.
Optimized png_combine_row() when rows are aligned. This gains a small
percentage for 16-bit and 32-bit pixels in the typical case where the
output row buffers are appropriately aligned. The optimization was not
previously possible because the png_struct buffer was always misaligned.
Removed two redundant tests for unitialized row.
Fixed a relatively harmless memory overwrite in compressed text writing
with a 1 byte zlib buffer.
Add ability to call png_read_update_info multiple times to pngvalid.c
Fixes for multiple calls to png_read_update_info. These fixes attend to
most of the errors revealed in pngvalid, however doing the gamma work
twice results in inaccuracies that can\'t be easily fixed. There is now
a warning in the code if this is going to happen.
Turned on multiple png_read_update_info in pngvalid transform tests.
Prevent libpng from overwriting unused bits at the end of the image when
it is not byte aligned, while reading. Prior to libpng-1.5.6 libpng would
overwrite the partial byte at the end of each row if the row width was not
an exact multiple of 8 bits and the image is not interlaced.
Made png_ptr->prev_row an aligned pointer into png_ptr->big_prev_row
(Mans Rullgard).
Changed misleading \"Missing PLTE before cHRM\" warning to \"Out of place cHRM\"
Added PNG_LSR() and PNG_LSL() macros to defend against buggy compilers that
evaluate non-taken code branches and complain about out-of-range shifts.
Renamed the local variable \'byte\' because it appears in a MSYS header
file.
Added #define PNG_ALIGN_TYPE PNG_ALIGN_NONE to contrib/pngminim/
*/pngusr.h
