| <description> |
| <p> |
| Diego E. Petteno` reported multiple integer overflows in glib/gbase64.c |
| when converting a long string from or to a base64 representation. |
| </p> |
| </description> |
| <impact type="normal"> |
| <p> |
| A remote attacker could entice a user or automated system to perform a |
| base64 conversion via an application using GLib, possibly resulting in |
| the execution of arbitrary code. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All GLib 2.18 users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=dev-libs/glib-2.18.4-r1"</code> |
| <p> |
| All GLib 2.16 users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=dev-libs/glib-2.16.6-r1"</code> |
