https://notcve.org/view.php?id=CVE-2018-20482
GNU Tar through 1.30, when --sparse is used, mishandles file shrinkage during read access, which allows local users to cause a denial of service (infinite read loop in sparse_dump_region in sparse.c) by modifying a file that is supposed to be archived by a different user's process (e.g., a system backup running as root). GNU Tar, hasta la versión 1.30, cuando se emplea --sparse, gestiona de manera incorrecta el encogimiento de archivos durante el acceso de lectura, lo que permite que usuarios locales provoquen una denegación de servicio (bucle infinito de lectura en sparse_dump_region en sparse.c) modificando un archivo que debería ser archivado por el proceso de un usuario diferente (por ejemplo, un backup del sistema que se ejecuta como root). • http://git.savannah.gnu.org/cgit/tar.git/commit/?id=c15c42ccd1e2377945fd0414eca1a49294bff454 http://lists.gnu.org/archive/html/bug-tar/2018-12/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00077.html http://www.securityfocus.com/bid/106354 https://lists.debian.org/debian-lts-announce/2018/12/msg00023.html https://lists.debian.org/debian-lts-announce/2021/11/msg00025.html https://news.ycombinator.com/item?id=18745431 https://security.gentoo.org/glsa/201903- • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

https://notcve.org/view.php?id=CVE-2016-6321
Directory traversal vulnerability in the safer_name_suffix function in GNU tar 1.14 through 1.29 might allow remote attackers to bypass an intended protection mechanism and write to arbitrary files via vectors related to improper sanitization of the file_name parameter, aka POINTYFEATHER. Vulnerabilidad de salto de directorio en la función safer_name_suffix en GNU tar 1.14 hasta la versión 1.29 podrían permitir a atacantes remotos eludir un mecanismo de protección previsto y escribir en archivos arbitarios a través de vectores relacionados con una desinfección inadecuada del parámetro file_name, también conocida como POINTYFEATHER. The GNU tar archiver can be tricked into extracting files and directories in the given destination, regardless of the path name(s) specified on the command line. Versions 1.14 through 1.29 are affected. • http://git.savannah.gnu.org/cgit/tar.git/commit/?id=7340f67b9860ea0531c1450e5aa261c50f67165d http://lists.gnu.org/archive/html/bug-tar/2016-10/msg00016.html http://packetstormsecurity.com/files/139370/GNU-tar-1.29-Extract-Pathname-Bypass.html http://seclists.org/fulldisclosure/2016/Oct/102 http://seclists.org/fulldisclosure/2016/Oct/96 http://www.debian.org/security/2016/dsa-3702 http://www.securityfocus.com/bid/93937 http://www.ubuntu.com/usn/USN-3132-1 https://lists.apache. • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

Heap-based buffer overflow in the rmt_read__ function in lib/rtapelib.c in the rmt client functionality in GNU tar before 1.23 and GNU cpio before 2.11 allows remote rmt servers to cause a denial of service (memory corruption) or possibly execute arbitrary code by sending more data than was requested, related to archive filenames that contain a : (colon) character. Desbordamiento de búfer basado en pila en la función rmt_read__ en lib/rtapelib.c en la funcionalidad de cliente rmt en GNU tar anterior v1.23 y GNU cpio anterior v2.11 permite a servidores rmt remotos causar una denegación de servicio (caída de memoria) o probablemente ejecutar código de su elección con el envío de más datos de los requeridos, relacionado con nombre de ficheros que contienen el caracter : (dos puntos). • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10691 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10705 http://lists.fedoraproject.org/pipermail/package-announce/2010-March/036668.html http://lists.fedoraproject.org/pipermail/package-announce/2010-March/037395.html http://lists.fedoraproject.org/pipermail/package-announce/2010-March/037401.html http://lists.fedoraproject.org/pipermail/package-announce/2010-March/038134.html http://lists.fedoraproject.org/pipermail/package-announce/2010-Marc • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •
