<title>X Font Server: Multiple Vulnerabilities</title> |
22 |
<synopsis> |
23 |
Three vulnerabilities have been discovered in the X Font Server possibly |
24 |
allowing local attackers to gain elevated privileges. |

The X.Org X11 X Font Server provides a standard mechanism for an X |
41 |
server to communicate with a font renderer. |

46 |
iDefense reported that the xfs init script does not correctly handle a |
47 |
race condition when setting permissions of a temporary file |
48 |
(CVE-2007-3103). Sean Larsson discovered an integer overflow |
49 |
vulnerability in the build_range() function possibly leading to a |
50 |
heap-based buffer overflow when handling "QueryXBitmaps" and |
51 |
"QueryXExtents" protocol requests (CVE-2007-4568). Sean Larsson also |
52 |
discovered an error in the swap_char2b() function possibly leading to a |
53 |
heap corruption when handling the same protocol requests |
54 |
(CVE-2007-4990). |

<impact type="high"> |
58 |
<p> |
59 |
The first issue would allow a local attacker to change permissions of |
60 |
arbitrary files to be world-writable by performing a symlink attack. |
61 |
The second and third issues would allow a local attacker to execute |
62 |
arbitrary code with privileges of the user running the X Font Server, |
63 |
usually xfs. |
64 |
</p> |
65 |
</impact> |
66 |
<workaround> |
67 |
<p> |
68 |
There is no known workaround at this time. |
69 |
</p> |
70 |
</workaround> |
71 |
<resolution> |
72 |
<p> |
73 |
All X Font Server users should upgrade to the latest version: |
74 |
</p> |

<code> |
76 |
# emerge --sync |
77 |
# emerge --ask --oneshot --verbose ">=x11-apps/xfs-1.0.5"</code> |
