CVE-2012-4167

Vulnerability

An integer overflow vulnerability exists in Adobe Flash Player and Adobe AIR. The flaw resides in the handling of unspecified vectors within the Flash Player runtime. Affected versions include Flash Player before 10.3.183.23 and 11.x before 11.4.402.265 on Windows and Mac OS X, before 10.3.183.23 and 11.x before 11.2.202.238 on Linux, before 11.1.111.16 on Android 2.x and 3.x, and before 11.1.115.17 on Android 4.x; Adobe AIR before 3.4.0.2540; and Adobe AIR SDK before 3.4.0.2540 [1][2][3].

Exploitation

An attacker can exploit this vulnerability by enticing a user to open a specially crafted SWF file, for example via a malicious web page or email attachment. No authentication is required, and the attack can be conducted remotely. The integer overflow leads to memory corruption, which can be leveraged to execute arbitrary code [2][3].

Impact

Successful exploitation allows an attacker to execute arbitrary code with the privileges of the user running the Flash Player. This can lead to full compromise of the affected system, including data theft, installation of malware, or further network propagation [2][3].

Mitigation

Adobe has released updated versions to address this vulnerability. Users should upgrade to Flash Player 10.3.183.23, 11.4.402.265 (Windows/Mac), 11.2.202.238 (Linux), 11.1.111.16 (Android 2.x/3.x), 11.1.115.17 (Android 4.x), or AIR 3.4.0.2540 as appropriate. Red Hat and Gentoo have also issued updates [2][3]. No workaround is known [3].
