Synopsis:          Moderate: libpng security update
Advisory ID:       SLSA-2015:2596-1
Issue Date:        2015-12-09
CVE Numbers:       CVE-2015-8126
                   CVE-2015-8472
--

It was discovered that the png_get_PLTE() and png_set_PLTE() functions of
libpng did not correctly calculate the maximum palette sizes for bit
depths of less than 8. In case an application tried to use these functions
in combination with properly calculated palette sizes, this could lead to
a buffer overflow or out-of-bounds reads. An attacker could exploit this
to cause a crash or potentially execute arbitrary code by tricking an
unsuspecting user into processing a specially crafted PNG image. However,
the exact impact is dependent on the application using the library.
