[slackware-security]  libpng (SSA:2015-337-01)

New libpng packages are available for Slackware 13.0, 13.1, 13.37, 14.0, 14.1,
and -current to fix security issues.


Here are the details from the Slackware 14.1 ChangeLog:
+--------------------------+
patches/packages/libpng-1.4.17-i486-1_slack14.1.txz:  Upgraded.
  Fixed buffer overflows in the png_set_PLTE(), png_get_PLTE(),
  png_set_tIME(), and png_convert_to_rfc1123() functions that allow
  attackers to cause a denial of service (application crash) or
  possibly have unspecified other impact via a small bit-depth value
  in an IHDR (aka image header) chunk in a PNG image.
  For more information, see:

    http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-8126.
