CESA-2006:0195: tar security update



An updated tar package that fixes a path traversal flaw is now available. This update has been rated as having low security impact by the CentOS Security Response Team.

The GNU tar program saves many files together in one archive and can restore individual files (or all of the files) from that archive. In 2002, a path traversal flaw was found 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-2002-0399). CentOS included a backported security patch to correct this issue in CentOS Linux 3, and an erratum for CentOS Enterprise Linux 2.1 users was issued. During internal testing, we discovered that our backported security patch contained an incorrect optimization and therefore was not sufficient to completely correct this vulnerability. The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CVE-2005-1918 to this issue. Users of tar should upgrade to this updated package, which contains a replacement backported patch to correct this issue.
