17 Mar 2021 — The Debian shadow package before 1:4.5-1 for Shadow incorrectly lists pts/0 and pts/1 as physical terminals in /etc/securetty. This allows local users to login as password-less users even if they are connected by non-physical means such as SSH (hence bypassing PAM's nullok_secure configuration). This notably affects environments such as virtual machines automatically generated with a default blank root password, allowing all local users to escalate privileges. El paquete shadow de Debian versiones anteriore... • https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=877374 • CWE-269: Improper Privilege Management •

03 Dec 2019 — shadow: TOCTOU (time-of-check time-of-use) race condition when copying and removing directory trees shadow: condición de carrera TOCTOU (de tiempo de comprobación y tiempo de uso) cuando se copia y elimina árboles de directorio. Florian Weimer discovered that shadow was not properly copying and removing user directory trees, which could lead to a race condition. A local attacker could possibly use this issue to setup a symlink attack and alter or remove directories without authorization. • https://access.redhat.com/security/cve/cve-2013-4235 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •

04 Nov 2019 — There is a possible tty hijacking in shadow 4.x before 4.1.5 and sudo 1.x before 1.7.4 via "su - user -c program". The user session can be escaped to the parent session by using the TIOCSTI ioctl to push characters into the input buffer to be read by the next process. Se presenta un posible secuestro de tty en shadow versiones 4.x anteriores a 4.1.5 y sudo versiones 1.x anteriores a 1.7.4 por medio de "su - user -c program".

04 Aug 2017 — 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 m... • https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=756630 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

28 May 2006 — useradd in shadow-utils before 4.0.3, and possibly other versions before 4.0.8, does not provide a required argument to the open function when creating a new user mailbox, which causes the mailbox to be created with unpredictable permissions and possibly allows attackers to read or modify the mailbox.
