CVE-2015-0327

Vulnerability

A heap-based buffer overflow exists in Adobe Flash Player before 13.0.0.269 and 14.x through 16.x before 16.0.0.305 on Windows and OS X, and before 11.2.202.442 on Linux [1][2][3]. The vulnerability is triggered via unspecified vectors, likely involving crafted SWF content. Affected versions include those bundled with Internet Explorer and Microsoft Edge on Windows [1], as well as the standalone player on Linux distributions [2][3].

Exploitation

An attacker can exploit this vulnerability by delivering a malicious SWF file, typically through a compromised website or email attachment. No authentication is required; user interaction (e.g., visiting a malicious page or opening a crafted file) is sufficient to trigger the overflow. The exact exploitation steps are not detailed in the available references, but the heap-based nature suggests a memory corruption that can be leveraged for code execution.

Impact

Successful exploitation allows an attacker to execute arbitrary code with the privileges of the user running Flash Player [1][2][3]. This can lead to full system compromise, including data theft, installation of malware, or further lateral movement. Additionally, the vulnerability may enable denial of service or information disclosure [3].

Mitigation

Adobe released fixed versions: 13.0.0.269, 16.0.0.305, and 11.2.202.442 [1][2][3]. Microsoft provided updates for Internet Explorer and Microsoft Edge via security advisory 2755801 [1]. Red Hat and Gentoo advisories recommend updating to the patched versions [2][3]. No workaround is available [3]. Users should apply updates immediately.
