15 Dec 2007 — etc-update in Portage before 2.1.3.11 on Gentoo Linux relies on the umask to set permissions for the merge file, often resulting in permissions weaker than those of the original files, which might allow local users to obtain sensitive information by reading the merge file. etc-update en Portage before 2.1.3.11 sobre Gentoo Linux depende de umask para asignar permisos al fichero a unir, normalmente como resultado de permisos débiles que los archivos orignales, lo cual podría permitir a usuarios locales obten... • http://bugs.gentoo.org/show_bug.cgi?id=193589 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
