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. • https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=756630 https://bugs.launchpad.net/ubuntu/+source/shadow/+bug/1266675 https://github.com/shadow-maint/shadow/commit/954e3d2e7113e9ac06632aee3c69b8d818cc8952 https://lists.debian.org/debian-lts-announce/2021/03/msg00020.html https://security.gentoo.org/glsa/201710-16 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
