Descriptions
Integer underflow in the xTrapezoidValid macro in render/picture.h in X.Org allows context-dependent attackers to cause a denial of service (crash) via a negative bottom value.
Underflow de entero en la macro xTrapezoidValid en render/picture.h de X.Org permite a atacantes dependientes de contexto causar una denegación de servicio (crash) a través de un valor mínimo negativo .
X.Org is an open source implementation of the X Window System. It provides the basic low-level functionality that full-fledged graphical user interfaces are designed upon. An integer overflow, which led to a heap-based buffer overflow, was found in the way X.Org server handled trapezoids. A malicious, authorized client could use this flaw to crash the X.Org server or, potentially, execute arbitrary code with root privileges. All xorg-x11-server users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.
