[ol7_developer_EPEL] pngcheck-2.4.0-7.el7.x86_64

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.

• Thu Jan 07 2021 Benjamin A. Beasley <code@musicinmybrain.net> - 2.4.0-7

  - Fix buffer overflow on large MNG LOOP chunk (RHBZ#1908559)

• Thu Jan 07 2021 Benjamin A. Beasley <code@musicinmybrain.net> - 2.4.0-6

  - Fix a buffer overrun for certain invalid MNG PPLT chunk contents
    (RHBZ#1907428).

• Mon Dec 14 2020 Benjamin A. Beasley <code@musicinmybrain.net> - 2.4.0-5

  - 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 <code@musicinmybrain.net> - 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
  - Use name macro when referencing patches.
  - Add BR on make in anticipation of
    https://fedoraproject.org/wiki/Changes/Remove_make_from_BuildRoot.
  - 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
  - Add rpmlintrc rules for -extras subpackage
  - Add rpmlintrc file to suppress spurious rpmlint warnings

• Mon Nov 30 2020 Benjamin A. Beasley <code@musicinmybrain.net> - 2.3.0-5

  - Fix null pointer dereference in pngcheck when -f is given and the sCAL chunk
    is missing the pixel height.

• Fri Nov 13 2020 Benjamin A. Beasley <code@musicinmybrain.net> - 2.3.0-4

  - Fix buffer overflow (RHBZ #1897485)

• Wed Oct 28 2020 Benjamin A. Beasley <code@musicinmybrain.net> - 2.3.0-3

  - Add _hardened_build macro for EPEL

• Wed Oct 28 2020 Benjamin A. Beasley <code@musicinmybrain.net> - 2.3.0-2

  - Work around Makefile.unx not actually using LDFLAGS; this fixes hardened
    build (PIE)

• Thu Oct 15 2020 Benjamin A. Beasley <code@musicinmybrain.net> - 2.3.0-1

  - Initial import (#1886858)
