Scientific Linux Security Update : libpng on SL7.x x86_64

This script is Copyright (C) 2015-2016 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

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. (CVE-2015-8126, CVE-2015-8472)
