The new utilities # licensed under GPLv2+ are compiled from the gpl/ subdirectory and packaged in # the extras subpackage. License: MIT URL: http://www.libpng.org/pub/png/apps/pngcheck.html Source0: http://www.libpng.org/pub/png/src/%{name}-%{version}.tar.gz BuildRequires: gcc BuildRequires: pkgconfig(zlib) BuildRequires: make %description pngcheck verifies the integrity of PNG, JNG and MNG files (by checking the internal 32-bit CRCs [checksums] and decompressing the image data); it can optionally dump almost all of the chunk-level information in the image in human-readable form. For example, it can be used to print the basic statistics about an image (dimensions, bit depth, etc.); to list the color and transparency info in its palette (assuming it has one); or to extract the embedded text annotations. This is a command-line program with batch capabilities. The current release supports all PNG, MNG and JNG chunks, including the newly approved sTER stereo-layout chunk. It correctly reports errors in all but two of the images in Chris Nokleberg's brokensuite-20061204. %package extras Summary: Helper utilities distributed with %{name} License: GPLv2+ %description extras Included with pngcheck (since version 2.1.0) are two helper utilities: - pngsplit - break a PNG, MNG or JNG image into constituent chunks (numbered for easy reassembly) - png-fix-IDAT-windowsize - fix minor zlib-header breakage caused by libpng 1.2.6 %prep %autosetup %build %set_build_flags %make_build -f Makefile.unx \ CFLAGS="${CFLAGS-} -DUSE_ZLIB $(pkg-config --cflags zlib)" \ LIBS="${LDFLAGS-} $(pkg-config --libs zlib)" %install install -t '%{buildroot}%{_bindir}' -D -p \ pngcheck pngsplit png-fix-IDAT-windowsize install -t '%{buildroot}%{_mandir}/man1' -D -m 0644 -p *.1 gpl/*.1 %files %license LICENSE %doc CHANGELOG %doc README %{_bindir}/pngcheck %{_mandir}/man1/pngcheck.1* %files extras %license gpl/COPYING %doc CHANGELOG %doc README %{_bindir}/pngsplit %{_bindir}/png-fix-IDAT-windowsize %{_mandir}/man1/pngsplit.1* %{_mandir}/man1/png-fix-IDAT-windowsize.1* %changelog * Fri Jul 22 2022 Fedora Release Engineering 3.0.3-6 - Rebuilt for https://fedoraproject.org/wiki/Fedora_37_Mass_Rebuild * Fri Jan 21 2022 Fedora Release Engineering 3.0.3-5 - Rebuilt for https://fedoraproject.org/wiki/Fedora_36_Mass_Rebuild * Fri Jul 23 2021 Fedora Release Engineering 3.0.3-4 - Rebuilt for https://fedoraproject.org/wiki/Fedora_35_Mass_Rebuild * Wed Jul 21 2021 Benjamin A.

Beasley - 3.0.0-4 - Fix buffer overflow on large MNG LOOP chunk (RHBZ#1908559); not built in Fedora * Mon Dec 14 2020 Benjamin A. Beasley - 3.0.0-3 - Fix a buffer overrun for certain invalid MNG PPLT chunk contents (RHBZ#1907428); not built in Fedora * Mon Dec 14 2020 Benjamin A. Beasley - 3.0.0-2 - Previous fix for buffer overrun printing the contents of the sPLT chunk in certain malformed inputs (RHBZ#1905775) was incomplete; it should be properly fixed now. * Sun Dec 13 2020 Benjamin A. Beasley - 3.0.0-1 - New upstream version 3.0.0 incorporating all patches in 2.4.0-4, and removing the -f option * Sun Dec 13 2020 Benjamin A. Beasley - 2.4.0-4 - Bounds-check all accesses into enumerated-value name arrays; a malformed file could have caused a buffer overrun in several of these cases. (RHBZ#1902810) - Fix buffer overrun when print_buffer() is passed a nonpositive size, which can occur in practice for certain malformed inputs. (RHBZ#1902810) - In some cases, the chunk length from the file data (sz) is used to index into the read buffer without sufficient bounds-checking, leading to a buffer overrun. Fix this for PPLT, hIST, sCAL, FRAM, SAVE, nEED, PAST, DISC, DROP, DBYK, ORDR, and SEEK chunks. (RHBZ#1902810) - Fix buffer overrun printing the contents of the sPLT chunk in certain malformed inputs. (RHBZ#1905775) - Backport fix for off-by-one bug in check_magic() from 3.0.0 - Backport fix for zlib version warnings going to stdout from 3.0.0 * Mon Nov 30 2020 Benjamin A. Beasley - 2.4.0-3 - Fix null pointer dereference in pngcheck when -f is given and the sCAL chunk is missing the pixel height. - Use name macro when referencing patches. - Add BR on make in anticipation of https://fedoraproject.org/wiki/Changes/Remove_make_from_BuildRoot. * Fri Nov 13 2020 Benjamin A. Beasley - 2.4.0-2 - Fix buffer overflow (RHBZ #1897485) * Sun Nov 1 2020 Benjamin A. Beasley - 2.4.0-1 - New upstream version 2.4.0 - Added new license file for main package (same MIT-style license) - Drop format-security patch, now upstreamed - Use upstreamed man pages; no need to generate with help2man anymore * Sat Oct 31 2020 Benjamin A. Beasley - 2.3.0-5 - Add rpmlintrc rules for -extras subpackage * Sat Oct 31 2020 Benjamin A. Beasley - 2.3.0-4 - Add rpmlintrc file to suppress spurious rpmlint warnings * Wed Oct 28 2020 Benjamin A. Beasley - 2.3.0-3 - Add _hardened_build macro for EPEL * Wed Oct 28 2020 Benjamin A. Beasley - 2.3.0-2 - Work around Makefile.unx not actually using LDFLAGS; this fixes hardened build (PIE) * Thu Oct 15 2020 Benjamin A. Beasley - 2.3.0-1 - Initial import (#1886858)
