Synopsis |
| 17 |
======== |
| 18 |
|
| 19 |
Multiple vulnerabilities in Xfce might allow user-assisted attackers to |
| 20 |
execute arbitrary code. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
Xfce is a GTK+ 2 based desktop environment that allows to run a modern |
| 26 |
desktop environment on modest hardware. |
| 27 |
|
| 28 |
Affected packages |

Description |
| 41 |
=========== |
| 42 |
|
| 43 |
Gregory Andersen reported that the Xfce4 panel does not correctly |
| 44 |
calculate memory boundaries, leading to a stack-based buffer overflow |
| 45 |
in the launcher_update_panel_entry() function (CVE-2007-6531). Daichi |
| 46 |
Kawahata reported libxfcegui4 did not copy provided values when |
| 47 |
creating "SessionClient" structs, possibly leading to access of freed |
| 48 |
memory areas (CVE-2007-6532). |
| 49 |
|
| 50 |
Impact |
| 51 |
====== |
| 52 |
|
| 53 |
A remote attacker could entice a user to install a specially crafted |
| 54 |
"rc" file to execute arbitrary code via long strings in the "Name" and |
| 55 |
"Comment" fields or via unspecified vectors involving the second |
| 56 |
vulnerability. |
| 57 |
|
| 58 |
Workaround |
| 59 |
========== |
| 60 |
|
| 61 |
There is no known workaround at this time. |
| 62 |
|
| 63 |
Resolution |
| 64 |
========== |
| 65 |
|
| 66 |
All Xfce4 panel users should upgrade to the latest version: |
| 67 |
|
| 68 |
# emerge --sync |
| 69 |
# emerge --ask --oneshot --verbose ">=xfce-base/xfce4-panel-4.4.2" |
| 70 |
|
| 71 |
All libxfcegui4 users should upgrade to the latest version: |
| 72 |
|
| 73 |
# emerge --sync |
| 74 |
# emerge --ask --oneshot --verbose ">=xfce-base/libxfcegui4-4.4.2" |
| 75 |
|
| 76 |
Please refer to the Upgrading section of the Xfce Configuration Guide |
| 77 |
in case you are upgrading from Xfce 4.2. |
