CVSS: 9.8EPSS: 0%CPEs: 8EXPL: 0CVE-2022-1664 – directory traversal for in-place extracts with untrusted v2 and v3 source packages with debian.tar
https://notcve.org/view.php?id=CVE-2022-1664
Dpkg::Source::Archive in dpkg, the Debian package management system, before version 1.21.8, 1.20.10, 1.19.8, 1.18.26 is prone to a directory traversal vulnerability. When extracting untrusted source packages in v2 and v3 source package formats that include a debian.tar, the in-place extraction can lead to directory traversal situations on specially crafted orig.tar and debian.tar tarballs. La función Dpkg::Source::Archive en dpkg, el sistema de administración de paquetes de Debian, versiones anteriores a 1.21.8, 1.20.10, 1.19.8, 1.18.26, es propenso a una vulnerabilidad de salto de directorio. Cuando son extraídos paquetes fuente no confiables en formatos de paquetes fuente v2 y v3 que incluyen un debian.tar, la extracción en el lugar puede conllevar a situaciones de salto de directorio en los tarballs orig.tar y debian.tar especialmente diseñados • https://git.dpkg.org/cgit/dpkg/dpkg.git/commit/?id=1f23dddc17f69c9598477098c7fb9936e15fa495 https://git.dpkg.org/cgit/dpkg/dpkg.git/commit/?id=58814cacee39c4ce9e2cd0e3a3b9b57ad437eff5 https://git.dpkg.org/cgit/dpkg/dpkg.git/commit/?id=7a6c03cb34d4a09f35df2f10779cbf1b70a5200b https://git.dpkg.org/cgit/dpkg/dpkg.git/commit/?id=faa4c92debe45412bfcf8a44f26e827800bb24be https://lists.debian.org/debian-lts-announce/2022/05/msg00033.html https://lists.debian.org/debian-security-announce/2022/msg00115.html https://security • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

https://notcve.org/view.php?id=CVE-2017-8283
dpkg-source in dpkg 1.3.0 through 1.18.23 is able to use a non-GNU patch program and does not offer a protection mechanism for blank-indented diff hunks, which allows remote attackers to conduct directory traversal attacks via a crafted Debian source package, as demonstrated by use of dpkg-source on NetBSD. Dpkg-source en dpkg en las versiones comprendidas entre la 1.3.0 y la 1.18.23 es capaz de usar un programa de parches non-GNU que no ofrece un mecanismo de protección para diff hunks identadas en blanco, lo que permite a atacantes remotos realizar ataques de salto de directorio a través de un paquete fuente Debian, como se demuestra mediante el uso de dpkg-source en NetBSD. • http://www.openwall.com/lists/oss-security/2017/04/20/2 http://www.securityfocus.com/bid/98064 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
