Descriptions

A certain debugging component in IBM AIX 5.3 and 6.1 does not properly handle the (1) _LIB_INIT_DBG and (2) _LIB_INIT_DBG_FILE environment variables, which allows local users to gain privileges by leveraging a setuid-root program to create an arbitrary root-owned file with world-writable permissions, related to libC.a (aka the XL C++ runtime library) in AIX 5.3 and libc.a in AIX 6.1.

Cierto componente de depuración en IBM AIX v5.3 y v6.1 no proporciona la gestión de los entornos (1) _LIB_INIT_DBG y (2) _LIB_INIT_DBG_FILE, que permite a usuarios locales obtener privilegios utilizando para ello un programa setuid-root para crear un archivo root-owned a su elección con permisos world-writable, relacionados con ibC.a (como la librería XL C++ runtime) en AIX v5.3 y libc.a en AIX v6.1.
