| file is a utility that guesses a file format by scanning binary data |
| for patterns. |

| <p> |
| Colin Percival from FreeBSD reported that the previous fix for the |
| file_printf() buffer overflow introduced a new integer overflow. |
| </p> |
| </description> |
| <impact type="high"> |
| <p> |
| A remote attacker could entice a user to run the file program on an |
| overly large file (more than 1Gb) that would trigger an integer |
| overflow on 32-bit systems, possibly leading to the execution of |
| arbitrary code with the rights of the user running file. |
| </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-4.21"</code> |
