Update Information:

An out-of-bounds read in png_convert_to_rfc1123() in png.c could potentially be
exploited by a crafted PNG file to leak information from an application's
memory
(CVE-2015-7981). Buffer overflow vulnerabilities in functions
png_get_PLTE/png_set_PLTE, allowing remote attackers to cause DoS to
application
or have unspecified other impact (CVE-2015-8126). Also includes various other
small bug fixes as detailed in the package changelog.
