Descriptions

Multiple directory traversal vulnerabilities in the (1) tar_extract_glob and (2) tar_extract_all functions in libtar 1.2.20 and earlier allow remote attackers to overwrite arbitrary files via a .. (dot dot) in a crafted tar file.

Múltiples vulnerabilidades de salto de directorio en las funciones (1) tar_extract_glob y (2) tar_extract_all en libtar 1.2.20 y anteriores permiten a atacantes remotos sobreescribir archivos arbitrarios a través de un .. (punto punto) en un archivo TAR manipulado.

A directory traversal attack was reported against libtar, a C library for manipulating tar archives. The application does not validate the filenames inside the tar archive, allowing to extract files in arbitrary path. An attacker can craft a tar file to override files beyond the tar_extract_glob and tar_extract_all prefix parameter. The updated packages have been patched to correct this issue.
