CVE-2015-7981 
Qixue Xiao discovered an out-of-bounds read vulnerability in the
png_convert_to_rfc1123 function. A remote attacker can potentially
take advantage of this flaw to cause disclosure of information from
process memory.

CVE-2015-8126 
Multiple buffer overflows were discovered in the png_set_PLTE and
png_get_PLTE functions. A remote attacker can take advantage of this
flaw to cause a denial of service (application crash) via a small
bit-depth value in an IHDR (image header) chunk in a PNG image.");
