Detailsinfo

A vulnerability, which was classified as critical, has been found in Apple Mac OS X up to 10.11.3 (Operating System). Affected by this issue is an unknown code of the component Python. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Heap-based buffer overflow in the png_combine_row function in libpng before 1.5.21 and 1.6.x before 1.6.16, when running on 64-bit systems, might allow context-dependent attackers to execute arbitrary code via a "very wide interlaced" PNG image.

The weakness was published 03/21/2016 by Alex as HT206167 as confirmed advisory (Website). The advisory is available at support.apple.com. This vulnerability is handled as CVE-2014-9495 since 01/03/2015. The attack may be launched remotely. No form of authentication is required for exploitation. The technical details are unknown and an exploit is not available. The advisory points out:

Multiple vulnerabilities existed in libpng versions prior to 1.6.20. These were addressed by updating libpng to version 1.6.20.

The vulnerability scanner Nessus provides a plugin with the ID 81063 (openSUSE Security Update : libpng16 (openSUSE-SU-2015:0161-1)), which helps to determine the existence of the flaw in a target environment.
