Fedora 24 : libpng10 (2016-1a7e14d084)

Medium Nessus Plugin ID 96350

Synopsis

The remote Fedora host is missing a security update.

Description

This update fixes an old NULL pointer dereference bug in png_set_text_2() discovered and patched by Patrick Keshishian (CVE-2016-10087). The potential 'NULL dereference' bug has existed in libpng since version 0.71 of June 26, 1995. To be vulnerable, an application has to load a text chunk into the png structure, then delete all text, then add another text chunk to the same png structure, which seems to be an unlikely sequence, but it has happened.

The update also fixes some documentation typos and an instance of undefined behavior.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected libpng10 package.
