| <background> |
| <p> |
| LibXfont is the X.Org font library. TightVNC is a VNC client/server for |
| X displays. |
| </p> |
| </background> |
| <description> |
| <p> |
| The libXfont code is prone to several integer overflows, in functions |
| ProcXCMiscGetXIDList(), bdfReadCharacters() and FontFileInitTable(). |
| TightVNC contains a local copy of this code and is also affected. |
| </p> |
| </description> |
| <impact type="high"> |
| <p> |
| A local attacker could use a specially crafted BDF Font to gain root |
| privileges on the vulnerable host. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All libXfont users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=x11-libs/libXfont-1.2.7-r1"</code> |
