CVE-2015-7647

Vulnerability

CVE-2015-7647 is an unspecified type confusion vulnerability in Adobe Flash Player. It affects versions before 18.0.0.255 and 19.x before 19.0.0.226 on Windows and OS X, and versions before 11.2.202.540 on Linux [1][2][3]. The vulnerability occurs when processing a specially crafted SWF file, leading to memory corruption.

Exploitation

An attacker can exploit this vulnerability by delivering a malicious SWF file to a victim, typically through a compromised website or email attachment. No authentication or user interaction beyond loading the SWF is required. The attacker must convince the victim to visit a page hosting the malicious content.

Impact

Successful exploitation allows arbitrary code execution within the context of the affected Adobe Flash Player process. This can lead to complete compromise of the victim's system, including data exfiltration, installation of malware, and further propagation.

Mitigation

Adobe released fixes in versions 18.0.0.255 and 19.0.0.226 for Windows/OS X, and version 11.2.202.540 for Linux. Subsequently, Red Hat updated its packages to version 11.2.202.548 [1][2]. Gentoo recommends upgrading to >=11.2.202.548 [3]. No workarounds are available; users must upgrade to a patched version.
