RHSA-2002-138: tar |

Check for the version of the tar packages Detailed Explanation for this Vulnerability Assessment The unzip and tar utilities contain vulnerabilities which can permit arbitrary files to be overwritten during archive extraction. The unzip and tar utilities are used for dealing with archives, which are multiple files stored inside of a single file. A directory traversal vulnerability in unzip version 5.42 and earlier, as well as GNU tar 1.13.19 and earlier, permits attackers to overwrite arbitrary files during archive extraction via a ".." (dot dot) in an extracted filename (CVE-2001-1267, CVE-2001-1268). In addition, unzip version 5.42 and earlier also permits attackers to overwrite arbitrary files during archive extraction via filenames in the archive that begin with the "/" (slash) character (CVE-2001-1269). During testing of the fix to GNU tar, we discovered that GNU tar 1.13.25 was still vulnerable to a modified version of the same problem. Red Hat has provided a patch to tar 1.3.25 to correct this problem (CVE-2002-0399). Users of unzip and tar are advised to upgrade to these errata packages, containing unzip version 5.50 and a patched version of GNU tar 1.13.25, which are not vulnerable to these issues.
