Descriptions
In shadow before 4.5, the newusers tool could be made to manipulate internal data structures in ways unintended by the authors. Malformed input may lead to crashes (with a buffer overflow or other memory corruption) or other unspecified behaviors. This crosses a privilege boundary in, for example, certain web-hosting environments in which a Control Panel allows an unprivileged user account to create subaccounts.
En las versiones de Shadow anteriores a la 4.5, la herramienta newusers podría utilizarse para manipular estructuras de datos internas de formas no permitidas por los desarrolladores. Las entradas manipuladas podrían llevar a caídas (con un desbordamiento de búfer u otros tipos de corrupción de memoria) o a otro tipo de comportamiento sin especificar. Esto provoca un límite de privilegios en, por ejemplo, ciertos entornos de hospedaje web en los que un Panel de Control permite que una cuenta de usuario sin privilegios cree subcuentas.
It was discovered that shadow incorrectly handled certain inputs. An attacker could possibly use this issue to cause a crash or expose sensitive information. This issue only affected Ubuntu 14.04 ESM and Ubuntu 16.04 ESM. It was discovered that shadow incorrectly handled certain inputs. An attacker could possibly use this issue to expose sensitive information.
