CVSS: 8.2EPSS: 0%CPEs: 7EXPL: 0CVE-2021-32803 – Arbitrary File Creation/Overwrite via insufficient symlink protection due to directory cache poisoning
https://notcve.org/view.php?id=CVE-2021-32803
The npm package "tar" (aka node-tar) before versions 6.1.2, 5.0.7, 4.4.15, and 3.2.3 has an arbitrary File Creation/Overwrite vulnerability via insufficient symlink protection. `node-tar` aims to guarantee that any file whose location would be modified by a symbolic link is not extracted. This is, in part, achieved by ensuring that extracted directories are not symlinks. Additionally, in order to prevent unnecessary `stat` calls to determine whether a given path is a directory, paths are cached when directories are created. This logic was insufficient when extracting tar files that contained both a directory and a symlink with the same name as the directory. • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://github.com/npm/node-tar/commit/9dbdeb6df8e9dbd96fa9e84341b9d74734be6c20 https://github.com/npm/node-tar/security/advisories/GHSA-r628-mhmh-qjhw https://www.npmjs.com/advisories/1771 https://www.npmjs.com/package/tar https://www.oracle.com/security-alerts/cpuoct2021.html https://access.redhat.com/security/cve/CVE-2021-32803 https://bugzilla.redhat.com/show_bug.cgi?id=1990415 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-59: Improper Link Resolution Before File Access ('Link Following') •

A flaw was found in the src/list.c of tar 1.33 and earlier. This flaw allows an attacker who can submit a crafted input file to tar to cause uncontrolled consumption of memory. The highest threat from this vulnerability is to system availability. Se detectó un fallo en el archivo src/list.c de tar versiones 1.33 y anteriores. Este fallo permite a un atacante que puede enviar un archivo de entrada diseñado a tar causar un consumo no controlado de memoria. • https://bugzilla.redhat.com/show_bug.cgi?id=1917565 https://git.savannah.gnu.org/cgit/tar.git/commit/?id=d9d4435692150fa8ff68e1b1a473d187cc3fd777 https://savannah.gnu.org/bugs/?59897 https://security.gentoo.org/glsa/202105-29 • CWE-125: Out-of-bounds Read CWE-401: Missing Release of Memory after Effective Lifetime •

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') •

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 •
