Executive brief
A vulnerability was identified in Google Chrome's graphics engine (ANGLE) that could allow a malicious website to bypass security checks. By tricking a user into visiting a specially crafted web page, an attacker could potentially access sensitive information or cause the browser to crash. This affects users on Windows, Mac, Linux, and Android platforms.
Technical details
A type confusion vulnerability exists in the libGLESv2 component of the Almost Native Graphics Layer Engine (ANGLE) used by Google Chrome. The flaw is rooted in an integer overflow (CWE-190) that occurs during the processing of graphics content. A remote attacker can exploit this by hosting a malicious HTML page; when a victim visits the page, the attacker can bypass buffer validation. This could lead to out-of-bounds memory access, potentially resulting in information disclosure, data integrity issues, or a denial-of-service (crash). The issue was resolved in Chrome version 55.0.2883.75 for desktop and 55.0.2883.84 for Android.
