Detailsinfo

A vulnerability, which was classified as critical, was found in Apple Mac OS X up to 10.11.3 (Operating System). This affects an unknown code block of the component Python. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as 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. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Buffer overflow in the png_read_IDAT_data function in pngrutil.c in libpng before 1.5.21 and 1.6.x before 1.6.16 allows context-dependent attackers to execute arbitrary code via IDAT data with a large width, a different vulnerability than CVE-2014-9495.

The weakness was released 03/21/2016 as HT206167 as confirmed advisory (Website). It is possible to read the advisory at support.apple.com. This vulnerability is uniquely identified as CVE-2015-0973 since 01/10/2015. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. The technical details are unknown and an exploit is not publicly 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.
