Publisher Name: OpenPKG GmbH Publisher Home: http://openpkg.com/ Advisory Id (public): OpenPKG-SA-2006.038 Advisory Type: OpenPKG Security Advisory (SA) Advisory Directory: http://openpkg.com/go/OpenPKG-SA Advisory Document: http://openpkg.com/go/OpenPKG-SA-2006.038 Advisory Published: 2006-12-08 17:40 UTC Issue Id (internal): OpenPKG-SI-20061127.01 Issue First Created: 2006-11-27 Issue Last Modified: 2006-12-08 Issue Revision: 06 ____________________________________________________________________________ Subject Name: GNU tar Subject Summary: archive format utility Subject Home: http://www.gnu.org/software/tar/ Subject Versions: * <= 1.16 Vulnerability Id: CVE-2006-6097, CVE-2002-1216 Vulnerability Scope: global (not OpenPKG specific) Attack Feasibility: run-time Attack Vector: remote network Attack Impact: manipulation of data Description: The archive format utility GNU tar [0], versions up to and including 1.16, allows user-assisted attackers to overwrite arbitrary files via a TAR format file that contains a "GNUTYPE_NAMES" record with a symbolic link. As the "GNUTYPE_NAMES" based "name mangling" functionality in TAR format files is (1) a GNU extension only, (2) is no longer supported for TAR file creation by GNU tar since a longer time and (3) the extraction of such records is too dangerous, the functionality has been deactivated by default now in OpenPKG. For backward compatibility (usually to extract already existing older TAR format files), the introduced command-line option "--allow-name-mangling" is available.
