GNU tar 1.16 and 1.15.1, and possibly other versions, allows user-assisted attackers to overwrite arbitrary files via a tar file that contains a GNUTYPE_NAMES record with a symbolic link, which is not properly handled by the extract_archive function in extract.c and extract_mangle function in mangle.c, a variant of CVE-2002-1216.
Teemu Salmela discovered a path traversal flaw in the way GNU tar extracted archives. A malicious user could create a tar archive that could write to arbitrary files to which the user running GNU tar has write access. (CVE-2006-6097)
