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". La sesión de usuario puede ser escapada a la sesión principal mediante el uso de la ioctl TIOCSTI para insertar caracteres en el búfer de entrada para ser leídos por el siguiente proceso. • http://www.openwall.com/lists/oss-security/2012/11/06/8 http://www.openwall.com/lists/oss-security/2013/05/20/3 http://www.openwall.com/lists/oss-security/2013/11/28/10 http://www.openwall.com/lists/oss-security/2013/11/29/5 http://www.openwall.com/lists/oss-security/2014/10/20/9 http://www.openwall.com/lists/oss-security/2014/10/21/1 http://www.openwall.com/lists/oss-security/2014/12/15/5 http://www.openwall.com/lists/oss-security/201 • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2018-16588
Privilege escalation can occur in the SUSE useradd.c code in useradd, as distributed in the SUSE shadow package through 4.2.1-27.9.1 for SUSE Linux Enterprise 12 (SLE-12) and through 4.5-5.39 for SUSE Linux Enterprise 15 (SLE-15). Non-existing intermediate directories are created with mode 0777 during user creation. Given that they are world-writable, local attackers might use this for privilege escalation and other unspecified attacks. NOTE: this would affect non-SUSE users who took useradd.c code from a 2014-04-02 upstream pull request; however, no non-SUSE distribution is known to be affected. Puede ocurrir un escalado de privilegios en el código SUSE useradd en useradd.c, tal y como se distribuye en el paquete SUSE shadow hasta la versión 4.2.1-27.9.1 para SUSE Linux Enterprise 12 (SLE-12) y hasta la versión 4.5-5.39 para SUSE Linux Enterprise 15 (SLE-15). • http://lists.opensuse.org/opensuse-security-announce/2018-09/msg00073.html • CWE-732: Incorrect Permission Assignment for Critical Resource •

https://notcve.org/view.php?id=CVE-2017-12424
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 •

/bin/login in shadow 4.0.18.1 in Debian GNU/Linux, and probably other Linux distributions, allows local users in the utmp group to overwrite arbitrary files via a symlink attack on a temporary file referenced in a line (aka ut_line) field in a utmp entry. /bin/login en shadow 4.0.18.1 en Debian GNU/Linux, y probablemente otras distribuciones de Linux, permiten a los usuarios locales en el el grupo utmp sobrescribir arbitrariamente archivos a través de un ataque de enlace simbólico en un archivo temporal referenciado en un campo línea (alias ut_line) en una entrada utmp. • https://www.exploit-db.com/exploits/7313 http://bugs.debian.org/332198 http://bugs.debian.org/505071 http://bugs.debian.org/505271 http://osvdb.org/52200 http://security.gentoo.org/glsa/glsa-200903-24.xml http://securityreason.com/securityalert/4695 http://www.mandriva.com/security/advisories?name=MDVSA-2009:062 http://www.securityfocus.com/archive/1/498769/100/0/threaded http://www.securityfocus.com/bid/32552 http://www.ubuntu.com/usn/usn-695-1 https:// • CWE-59: Improper Link Resolution Before File Access ('Link Following') •
