for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having Moderate
security impact. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available from the
CVE link in the References section.
The libpng packages contain a library of functions for creating and
manipulating PNG (Portable Network Graphics) image format files.
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)
All libpng users are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue.
