GDM is the GNOME display manager. |

<p> |
45 |
The result of a g_strsplit() call is incorrectly parsed in the files |
46 |
daemon/gdm.c, daemon/gdmconfig.c, gui/gdmconfig.c and |
47 |
gui/gdmflexiserver.c, allowing for a null pointer dereference. |

<impact type="low"> |
51 |
<p> |
52 |
A local user could send a crafted message to /tmp/.gdm_socket that |
53 |
would trigger the null pointer dereference and crash GDM, thus |
54 |
preventing it from managing future displays. |
55 |
</p> |
56 |
</impact> |
57 |
<workaround> |
58 |
<p> |
59 |
Restrict the write permissions on /tmp/.gdm_socket to trusted users |
60 |
only after each GDM restart. |
61 |
</p> |
62 |
</workaround> |
63 |
<resolution> |
64 |
<p> |
65 |
All GDM users should upgrade to the latest version: |
66 |
</p> |
67 |
<code> |
68 |
# emerge --sync |
69 |
# emerge --ask --oneshot --verbose "gnome-base/gdm"</code> |
