https://notcve.org/view.php?id=CVE-2017-2616
A race condition was found in util-linux before 2.32.1 in the way su handled the management of child processes. A local authenticated attacker could use this flaw to kill other processes with root privileges under specific conditions. Se ha encontrado una condición de carrera en util-linux en versiones anteriores a la 2.32.1 en la forma en la que "su" manejaba los procesos hijo.

CVE-2011-1675 – util-linux: mount fails to anticipate RLIMIT_FSIZE
https://notcve.org/view.php?id=CVE-2011-1675
mount in util-linux 2.19 and earlier attempts to append to the /etc/mtab.tmp file without first checking whether resource limits would interfere, which allows local users to trigger corruption of the /etc/mtab file via a process with a small RLIMIT_FSIZE value, a related issue to CVE-2011-1089. mount in util-linux v2.19 y anteriores, intenta añadir al fichero /etc/mtab.tmp sin primero comprobar si los limites del recurso interfieren, lo que permite a usuarios locales provocar una corrupción del fichero /etc/mtab mediante un proceso con un valor RLIMIT_FSIZE pequeño, un asunto relacionado con CVE-2011-1089. • http://openwall.com/lists/oss-security/2011/03/04/10 http://openwall.com/lists/oss-security/2011/03/04/11 http://openwall.com/lists/oss-security/2011/03/04/12 http://openwall.com/lists/oss-security/2011/03/04/9 http://openwall.com/lists/oss-security/2011/03/05/3 http://openwall.com/lists/oss-security/2011/03/05/7 http://openwall.com/lists/oss-security/2011/03/07/9 http://openwall.com/lists/oss-security/2011/03/14/16 http://openwall • CWE-399: Resource Management Errors •
CVE-2011-1677 – util-linux: umount may fail to remove /etc/mtab~ lock file

CVE-2008-1926 – util-linux: audit log injection via login
https://notcve.org/view.php?id=CVE-2008-1926
Argument injection vulnerability in login (login-utils/login.c) in util-linux-ng 2.14 and earlier makes it easier for remote attackers to hide activities by modifying portions of log events, as demonstrated by appending an "addr=" statement to the login name, aka "audit log injection." Vulnerabilidad de inyección de argumento en login (login-utils/login.c) de util-linux-ng 2.14 y anteriores, hace que atacantes remotos puedan esconder fácilmente sus actividades modificando partes del log de sucesos, como se ha demostrado añadiendo una sentencia "addr=" en el campo "name" del login, también conocido como "audit log injection." • http://git.kernel.org/?p=utils/util-linux-ng/util-linux-ng.git%3Ba=blobdiff%3Bf=login-utils/login.c%3Bh=230121316d953c59e7842c1325f6e9f326a37608%3Bhp=aad27794327c60391b5148b367d2c79338fc6ee4%3Bhb=8ccf0b253ac0f4f58d64bc9674de18bff5a88782%3Bhpb=3a4a13b12a8065b0b5354686d2807cce421a9973 http://git.kernel.org/?p=utils/util-linux-ng/util-linux-ng.git%3Ba=commit%3Bh=8ccf0b253ac0f4f58d64bc9674de18bff5a88782 http://secunia.com/advisories/29982 http://secunia.com/advisories/30014 http://secunia.com/advisories/35161 http://wiki.rpath.com/Advisories:rPSA-2009& • CWE-94: Improper Control of Generation of Code ('Code Injection') •
