Title
Mozilla Firefox和Firefox ESR ANGLE拒绝服务漏洞
Description
Mozilla Firefox和Firefox ESR都是美国Mozilla基金会开发的浏览器产品。Firefox是一款开源Web浏览器；Firefox ESR是Firefox的一个延长支持版本。Google ANGLE（Almost Native Graphics Layer Engine）是美国谷歌（Google）公司的一个图形层引擎，它允许Windows用户通过把OpenGL ES 2.0 API转译为DirectX 9或DirectX 11 API调用，来运行WebGL和其他OpenGL ES 2.0内容。 基于Windows平台的Mozilla Firefox 47.0之前版本和Firefox ESR 45.2之前45.x版本中使用的ANGLE中的‘TSymbolTableLevel’类存在拒绝服务漏洞。远程攻击者可通过使用WebGL着色器利用该漏洞造成拒绝服务（越边界写入和应用程序崩溃）。
