CVE-2015-8407

Vulnerability

Stack-based buffer overflow in Adobe Flash Player before 18.0.0.268 and 19.x and 20.x before 20.0.0.228 on Windows and OS X, and before 11.2.202.554 on Linux, as well as Adobe AIR before 20.0.0.204, AIR SDK before 20.0.0.204, and AIR SDK & Compiler before 20.0.0.204. The vulnerability is triggered via unspecified vectors, likely involving crafted SWF content [1].

Exploitation

An attacker can exploit this vulnerability by convincing a user to open a malicious Flash file, typically delivered via a web page or email. No authentication is required; the attacker only needs to craft a specially designed SWF file that triggers the stack buffer overflow when processed by the vulnerable Flash Player [1].

Impact

Successful exploitation allows an attacker to execute arbitrary code with the privileges of the affected process. This can lead to full system compromise, including data theft, installation of malware, or denial of service. The vulnerability is rated as critical due to the potential for remote code execution [1].

Mitigation

Adobe released fixed versions: Flash Player 18.0.0.268, 20.0.0.228, and 11.2.202.554 (Linux); AIR 20.0.0.204. Users should update to these versions or later. Gentoo recommends upgrading to >=www-plugins/adobe-flash-11.2.202.559 [1]. No workaround is available.
