Package: xorg Version: 1:7.1.0-10 Severity: important Tags: security Sean Larsson has reported some vulnerabilities in X.Org X11, which can be exploited by malicious, local users to gain escalated privileges.
The vulnerabilities are caused due to input validation errors within the ""ProcRenderAddGlyphs()" function of the "Renderer" extension and the "ProcDbeGetVisualInfo()" and "ProcDbeSwapBuffers()" functions of the "DBE" extension. This can be exploited to cause a memory corruption by sending specially crafted X requests to the X server. Successful exploitation may allow the execution of arbitrary code with the privileges of the X server, but requires that the "Renderer" or "DBE" extensions are loaded. The vulnerabilities are reported in version 7.1-1.1.0. Other versions may also be affected. Solution: Update to version 7.2 RC3.
