Descriptions

The Netscape Portable Runtime (NSPR) API 4.6.1 and 4.6.2, as used in Sun Solaris 10, trusts user-specified environment variables for specifying log files even when running from setuid programs, which allows local users to create or overwrite arbitrary files.

Las API 4.6.1 y 4.6.2 de Netscape Portable Runtime (NSPR), usadas en Sun Solaris 10, permiten variables de entorno definidas por el usuario para especificar ficheros de traza incluso cuando se ejecutan desde programas Setuid, que permiten a los usuarios locales crear o sobre-escribir ficheros de su elección.
