CVE-2016-4277

Vulnerability

Adobe Flash Player versions prior to 18.0.0.375 and 19.x through 23.x before 23.0.0.162 on Windows and OS X, and before 11.2.202.635 on Linux, contain an unspecified vulnerability that allows attackers to bypass intended access restrictions and obtain sensitive information [1][2]. The exact code path and conditions required are not disclosed in the available references, but the issue is distinct from CVE-2016-4271 and CVE-2016-4278.

Exploitation

An attacker can exploit this vulnerability by delivering a crafted SWF file to a user running an affected version of Adobe Flash Player. The attack requires no authentication and can be performed remotely, typically via a malicious website or embedded content. The specific exploitation steps are not detailed in the references, but the vulnerability is triggered through unspecified vectors [1][2].

Impact

Successful exploitation allows an attacker to bypass security restrictions and obtain sensitive information from the affected system. The impact is limited to information disclosure; the vulnerability does not directly enable code execution or denial of service, though other CVEs in the same advisory may have more severe impacts [1][2].

Mitigation

Adobe released fixed versions: 18.0.0.375, 23.0.0.162 (Windows/OS X), and 11.2.202.635 (Linux). Users should upgrade to these or later versions. Red Hat and Gentoo have issued advisories recommending updates [1][2]. No workaround is available for this specific vulnerability.
