In util-linux before 2.32-rc1, bash-completion/umount allows local users to gain privileges by embedding shell commands in a mountpoint name, which is mishandled during a umount command (within Bash) by a different user, as demonstrated by logging in as root and entering umount followed by a tab character for autocompletion. En util-linux, en versiones anteriores a la 2.32-rc1, bash-completion/umount permite que usuarios locales obtengan privilegios embebiendo comandos shell en un nombre mountpoint, que se gestiona de manera incorrecta durante un comando umount (en Bash) ejecutado por otro usuario. Esto se demuestra iniciando sesión como root y escribiendo unmount, seguido por un carácter de tabulador para autocompletar. • http://www.securityfocus.com/bid/103367 https://bugs.debian.org/892179 https://github.com/karelzak/util-linux/commit/75f03badd7ed9f1dd951863d75e756883d3acc55 https://github.com/karelzak/util-linux/issues/539 https://usn.ubuntu.com/4512-1 https://www.debian.org/security/2018/dsa-4134 •

CVSS: 4.9EPSS: 0%CPEs: 19EXPL: 0CVE-2016-5011 – util-linux: Extended partition loop in MBR partition table leads to DOS
https://notcve.org/view.php?id=CVE-2016-5011
The parse_dos_extended function in partitions/dos.c in the libblkid library in util-linux allows physically proximate attackers to cause a denial of service (memory consumption) via a crafted MSDOS partition table with an extended partition boot record at zero offset. La función parse_dos_extended en partitions/dos.c en la biblioteca libblkid en util-linux permite a atacantes físicamente próximos provocar una denegación de servicio (consumo de memoria) a través de una tabla de particiones MSDOS manipulada con un registro de arranque de partición extendida en desplazamiento cero. It was found that util-linux's libblkid library did not properly handle Extended Boot Record (EBR) partitions when reading MS-DOS partition tables. An attacker with physical USB access to a protected machine could insert a storage device with a specially crafted partition table that could, for example, trigger an infinite loop in systemd-udevd, resulting in a denial of service on that machine. • http://rhn.redhat.com/errata/RHSA-2016-2605.html http://www-01.ibm.com/support/docview.wss?uid=isg3T1024543 http://www-01.ibm.com/support/docview.wss?uid=nas8N1021801 http://www.openwall.com/lists/oss-security/2016/07/11/2 http://www.securityfocus.com/bid/91683 http://www.securitytracker.com/id/1036272 https://git.kernel.org/pub/scm/utils/util-linux/util-linux.git/commit/?id=7164a1c3 https://access.redhat.com/security/cve/CVE-2016-5011 https://bugzilla.redhat. •
