CVE-2011-3378

RPM v4.4.x hasta v4.9.x, probablemente antes de v4.9.1.2, permite a atacantes remotos provocar una denegación de servicio (corrupción de memoria) y posiblemente ejecutar código arbitrario a través de un paquete RPM con cabeceras manipuladas y "offsets" que no son manipulados correctamente cuando un paquete es consultado o instalado, relacionado con (1) la función regionSwab, (2) la función headerLoad, y (3) múltiples funciones en rpmio/rpmpgp.c.

The RPM Package Manager is a command line driven package management system capable of installing, uninstalling, verifying, querying, and updating software packages. Multiple flaws were found in the way the RPM library parsed package headers. An attacker could create a specially-crafted RPM package that, when queried or installed, would cause rpm to crash or, potentially, execute arbitrary code. Note: Although an RPM package can, by design, execute arbitrary code when installed, this issue would allow a specially-crafted RPM package to execute arbitrary code before its digital signature has been verified. Package downloads from the Red Hat Network remain secure due to certificate checks performed on the secure connection.
