Oracle Linux 7 : libpng (ELSA-2015-2596)

High Nessus Plugin ID 87302


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


From Red Hat Security Advisory 2015:2596 :

Updated libpng packages that fix one security issue are now available 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.


Update the affected libpng packages.
