CVE-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') •

CVE-2017-8283

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') •

CVE-2015-0860

https://notcve.org/view.php?id=CVE-2015-0860

Off-by-one error in the extracthalf function in dpkg-deb/extract.c in the dpkg-deb component in Debian dpkg 1.16.x before 1.16.17 and 1.17.x before 1.17.26 allows remote attackers to execute arbitrary code via the archive magic version number in an "old-style" Debian binary package, which triggers a stack-based buffer overflow. Error por un paso en la función extracthalf en dpkg-deb/extract.c en el componente dpkg-deb en Debian dpkg 1.16.x en versiones anteriores a 1.16.17 y 1.17.x en versiones anteriores a 1.17.26 permite a atacantes remotos ejecutar código arbitrario a través del número mágico de versión del archivo en un paquete binario de Debian 'old-style', lo que desencadena un desbordamiento de buffer basado en pila. • http://www.debian.org/security/2015/dsa-3407 http://www.ubuntu.com/usn/USN-2820-1 https://anonscm.debian.org/cgit/dpkg/dpkg.git/commit/dpkg-deb/extract.c?id=e65aa3db04eb908c9507d5d356a95cedb890814d https://blog.fuzzing-project.org/30-Stack-overflows-and-out-of-bounds-read-in-dpkg-Debian.html https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=798324 https://security.gentoo.org/glsa/201612-07 • CWE-189: Numeric Errors •

The dpkg-source command in Debian dpkg before 1.16.16 and 1.17.x before 1.17.25 allows remote attackers to bypass signature verification via a crafted Debian source control file (.dsc). El comando dpkg-source en Debian dpkg anterior a 1.16.16 y 1.17.x anterior a 1.17.25 permite a atacantes remotos evadir verificación de firmas a través de un fichero de control de fuentes de Debian (.dsc) manipulado. • http://lists.fedoraproject.org/pipermail/package-announce/2015-May/157387.html http://lists.opensuse.org/opensuse-updates/2015-06/msg00029.html http://www.debian.org/security/2015/dsa-3217 http://www.ubuntu.com/usn/USN-2566-1 • CWE-284: Improper Access Control •
