| execution of arbitrary code. |

| Qt is a cross-platform GUI toolkit used by KDE. |

| <description> |
| <p> |
| Qt links to a bundled vulnerable version of zlib when emerged with the |
| zlib USE-flag disabled. This may lead to a buffer overflow. |
| </p> |
| </description> |
| <impact type="normal"> |
| <p> |
| By creating a specially crafted compressed data stream, attackers can |
| overwrite data structures for applications that use Qt, resulting in a |
| Denial of Service or potentially arbitrary code execution. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| Emerge Qt with the zlib USE-flag enabled. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All Qt users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=x11-libs/qt-3.3.4-r8"</code> |
| </resolution> |
