CVE-2015-7627

Vulnerability

A critical memory corruption vulnerability exists in Adobe Flash Player before version 18.0.0.252 and 19.x before 19.0.0.207 on Windows and OS X, before version 11.2.202.535 on Linux, as well as Adobe AIR before 19.0.0.213, Adobe AIR SDK before 19.0.0.213, and Adobe AIR SDK & Compiler before 19.0.0.213. The flaw is triggered by unspecified vectors, likely involving malformed SWF content, leading to exploitable memory corruption [1][2].

Exploitation

An attacker can exploit this vulnerability by crafting a malicious SWF file that triggers memory corruption when processed by the affected Flash Player versions. The attack requires delivering the SWF file to a victim, typically through a web browser, and convincing the user to load a webpage containing the malicious content. No authentication is required, and the exploitation can be achieved remotely [2][3].

Impact

Successful exploitation of this vulnerability allows an attacker to execute arbitrary code in the context of the currently logged-in user, potentially leading to full system compromise. The attacker can also cause a denial of service (application crash) via memory corruption. This could result in sensitive information disclosure, installation of malware, or further system control [2][3].

Mitigation

Adobe released fixes addressing this vulnerability on October 15, 2015. For Windows and OS X, update to Flash Player 18.0.0.252 or 19.0.0.207; for Linux, update to version 11.2.202.535 or later (Red Hat Enterprise Linux users received 11.2.202.548). Adobe AIR users should upgrade to version 19.0.0.213 or later. Gentoo users can emerge version 11.2.202.548 or later. No workaround is available [1][2][3].
