A flaw was found in the util-linux chfn and chsh utilities when compiled with Readline support. The Readline library uses an "INPUTRC" environment variable to get a path to the library config file. When the library cannot parse the specified file, it prints an error message containing data from the file. This flaw allows an unprivileged user to read root-owned files, potentially leading to privilege escalation. This flaw affects util-linux versions prior to 2.37.4. • https://lore.kernel.org/util-linux/20220214110609.msiwlm457ngoic6w%40ws.net.home/T/#u https://security.gentoo.org/glsa/202401-08 https://security.netapp.com/advisory/ntap-20220331-0002 • CWE-209: Generation of Error Message Containing Sensitive Information •

A logic error was found in the libmount library of util-linux in the function that allows an unprivileged user to unmount a FUSE filesystem. This flaw allows an unprivileged local attacker to unmount FUSE filesystems that belong to certain other users who have a UID that is a prefix of the UID of the attacker in its string form. An attacker may use this flaw to cause a denial of service to applications that use the affected filesystems. Se ha encontrado un error lógico en la biblioteca libmount de util-linux en la función que permite a un usuario no privilegiado desmontar un sistema de archivos FUSE. Este fallo permite a un atacante local no privilegiado desmontar sistemas de archivos FUSE que pertenecen a otros usuarios determinados que presentan un UID que es un prefijo del UID del atacante en su forma de cadena. • http://packetstormsecurity.com/files/170176/snap-confine-must_mkdir_and_open_with_perms-Race-Condition.html http://seclists.org/fulldisclosure/2022/Dec/4 http://www.openwall.com/lists/oss-security/2022/11/30/2 https://bugzilla.redhat.com/show_bug.cgi?id=2024631https://access.redhat.com/security/cve/CVE-2021-3995 https://github.com/util-linux/util-linux/commit/57202f5713afa2af20ffbb6ab5331481d0396f8d https://mirrors.edge.kernel.org/pub/linux/utils/util-linux/v2.37/v2.37.3-ReleaseNotes https: • CWE-552: Files or Directories Accessible to External Parties •

A logic error was found in the libmount library of util-linux in the function that allows an unprivileged user to unmount a FUSE filesystem. This flaw allows a local user on a vulnerable system to unmount other users' filesystems that are either world-writable themselves (like /tmp) or mounted in a world-writable directory. An attacker may use this flaw to cause a denial of service to applications that use the affected filesystems. Se ha encontrado un error lógico en la biblioteca libmount de util-linux en la función que permite a un usuario no privilegiado desmontar un sistema de archivos FUSE. Este fallo permite a un usuario local en un sistema vulnerable desmontar los sistemas de archivos de otros usuarios que son de escritura mundial (como /tmp) o que están montados en un directorio de escritura mundial. • http://packetstormsecurity.com/files/170176/snap-confine-must_mkdir_and_open_with_perms-Race-Condition.html http://seclists.org/fulldisclosure/2022/Dec/4 http://www.openwall.com/lists/oss-security/2022/11/30/2 https://access.redhat.com/security/cve/CVE-2021-3996 https://bugzilla.redhat.com/show_bug.cgi?id=2024628 https://github.com/util-linux/util-linux/commit/166e87368ae88bf31112a30e078cceae637f4cdb https://mirrors.edge.kernel.org/pub/linux/utils/util-linux/v2.37/v2.37.3-ReleaseNotes https • CWE-552: Files or Directories Accessible to External Parties •

An integer overflow in util-linux through 2.37.1 can potentially cause a buffer overflow if an attacker were able to use system resources in a way that leads to a large number in the /proc/sysvipc/sem file. NOTE: this is unexploitable in GNU C Library environments, and possibly in all realistic environments. ** EN DISPUTA ** Un desbordamiento de enteros en util-linux hasta la versión 2.37.1 puede potencialmente causar un desbordamiento de búfer si un atacante fuera capaz de utilizar los recursos del sistema de una manera que lleve a un número grande en el archivo /proc/sysvipc/sem.
