| Jean-Sebastien Guay-Leroux reported an integer underflow in |
| file_printf function. |

| <impact type="high"> |
| <p> |
| A remote attacker could entice a user to run the "file" program on a |
| specially crafted file that would trigger a heap-based buffer overflow |
| possibly leading to the execution of arbitrary code with the rights of |
| the user running "file". Note that this vulnerability could be also |
| triggered through an automatic file scanner like amavisd-new. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| Since file is a system package, all Gentoo users should upgrade to the |
| latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=sys-apps/file-4.20"</code> |
