Description :
The libpng10 package contains an old version of libpng, a library of functions

Update Information:

This update addresses a couple of buffer overflows that might allow
 context-dependent attackers to execute arbitrary code via very wide PNG images.

ChangeLog:

* Fri Feb 27 2015 Paul Howarth <paul@city-fan.org> - 1.0.63-1
- Update to 1.0.63
  - Issue a png_error() instead of a png_warning() when width is potentially
    too large for the architecture, in case the calling application has
    overridden the default 1,000,000-column limit (fixes CVE-2014-9495 and
    CVE-2015-0973)
  - Quieted some harmless warnings from Coverity-scan
  - Display user limits in the output from pngtest (not packaged)
  - Changed PNG_USER_CHUNK_MALLOC_MAX from unlimited to 8,000,000; it only
    affects the maximum memory that can be allocated to an ancillary chunk,
    and does not limit the size of IDAT data, which is instead limited by
    PNG_USER_WIDTH_MAX
  - Rebuilt configure scripts with automake-1.15 and libtool-2.4.6
- Update soname patch
* Fri Nov 21 2014 Paul Howarth <paul@city-fan.org> 1.0.62-1
- update to 1.0.62
  - avoid out-of-bounds memory access while checking version string in
    pngread.c and pngwrite.c
  - build fix for Windows
- use %license where possible
