X.Org DBE和Render扩展多个整数溢出漏洞

X.Org是X.Org Foundation对X窗口系统的开源实现。 X.Org Render扩展的ProcRenderAddGlyphs函数及DBE扩展的ProcDbeGetVisualInfo和ProcDbeSwapBuffers函数没有正确验证用户输入，允许攻击者通过向X服务器发送特制的X请求触发整数溢出，本地攻击者可能利用此漏洞获取root用户权限。 X.org X11R6 6.9.0 X.org X11R7 7.1 X.org X11R7 7.0 临时解决方法：...

USN-280-1: X.org server vulnerability

The Render extension of the X.org server incorrectly calculated the size of a memory buffer, which led to a buffer overflow. A local attacker could exploit this to crash the X server or even execute arbitrary code with root privileges...
