A vulnerability, which was classified as critical, was found in Adobe Acrobat Reader up to 11.0.15 (Document Reader Software). This affects some unknown processing. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119.

This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Adobe Reader and Acrobat before 11.0.17, Acrobat and Acrobat Reader DC Classic before 15.006.30198, and Acrobat and Acrobat Reader DC Continuous before 15.017.20050 on Windows and OS X allow attackers to execute arbitrary code or cause a denial of service (memory corruption) via unspecified vectors, a different vulnerability than CVE-2016-4191, CVE-2016-4192, CVE-2016-4193, CVE-2016-4194, CVE-2016-4195, CVE-2016-4196, CVE-2016-4197, CVE-2016-4198, CVE-2016-4199, CVE-2016-4200, CVE-2016-4201, CVE-2016-4202, CVE-2016-4203, CVE-2016-4204, CVE-2016-4205, CVE-2016-4206, CVE-2016-4207, CVE-2016-4208, CVE-2016-4211, CVE-2016-4212, CVE-2016-4213, CVE-2016-4214, CVE-2016-4250, CVE-2016-4251, CVE-2016-4252, CVE-2016-4254, CVE-2016-4266, CVE-2016-4267, CVE-2016-4268, CVE-2016-4269, and CVE-2016-4270.

The weakness was disclosed 08/23/2016 by Steven Seeley with Zero Day Initiative as APSB16-26 as confirmed security bulletin (Website). The advisory is shared at helpx.adobe.com. The security bulletin contains:

August 23, 2016: added references to CVE-2016-4265, CVE-2016-4266, CVE-2016-4265, CVE-2016-4266, CVE-2016-4267, CVE-2016-4268, CVE-2016-4269 and CVE-2016-4270, which were inadvertently omitted from the bulletin.
APSB16-26 added CVE references weeks later. But the changelog lists some of them twice. This vulnerability is uniquely identified as CVE-2016-4265 since 04/27/2016. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. It demands that the victim is doing some kind of user interaction. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 04/07/2017).

The vulnerability scanner Nessus provides a plugin with the ID 92036 (Adobe Acrobat < 11.0.17 / 15.006.30198 / 15.017.20050 Multiple Vulnerabilities (APSB16-26) (Mac OS X)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family MacOS X Local Security Checks.

Upgrading to version 11.0.17, 15.006.30198 or 15.017.20050 eliminates this vulnerability. A possible mitigation has been published before and not just after the disclosure of the vulnerability.

The vulnerability is also documented in the vulnerability database at Tenable (92036). The entries 89076, 89077, 89078 and 89079 are pretty similar.
