Synopsis |
| 46 |
======== |
| 47 |
|
| 48 |
Multiple remote vulnerabilities have been found in the LCDd server, |
| 49 |
allowing execution of arbitrary code with the rights of the LCDd user. |
| 50 |
|
| 51 |
Background |
| 52 |
========== |
| 53 |
|
| 54 |
LCDproc is a program that displays various bits of real-time system |
| 55 |
information on an LCD. It makes use of a local server (LCDd) to collect |
| 56 |
information to display on the LCD. |
| 57 |
|
| 58 |
Affected packages |
| 59 |
================= |
| 60 |
|
| 61 |
------------------------------------------------------------------- |
| 62 |
Package / Vulnerable / Unaffected |
| 63 |
------------------------------------------------------------------- |
| 64 |
1 app-misc/lcdproc <= 0.4.4-r1 >= 0.4.5 |
| 65 |
|
| 66 |
Description |
| 67 |
=========== |
| 68 |
|
| 69 |
Due to insufficient checking of client-supplied data, the LCDd server |
| 70 |
is susceptible to two buffer overflows and one string buffer |
| 71 |
vulnerability. If the server is configured to listen on all network |
| 72 |
interfaces (see the Bind parameter in LCDproc configuration), these |
| 73 |
vulnerabilities can be triggered remotely. |
| 74 |
|
| 75 |
Impact |
| 76 |
====== |
| 77 |
|
| 78 |
These vulnerabilities allow an attacker to execute code with the rights |
| 79 |
of the user running the LCDproc server. By default, this is the |
| 80 |
"nobody" user. |
| 81 |
|
| 82 |
Workaround |
| 83 |
========== |
| 84 |
|
| 85 |
A workaround is not currently known for this issue. All users are |
| 86 |
advised to upgrade to the latest version of the affected package. |
| 87 |
|
| 88 |
Resolution |
| 89 |
========== |
| 90 |
|
| 91 |
LCDproc users should upgrade to version 0.4.5 or later: |
| 92 |
|
| 93 |
# emerge sync |
| 94 |
|
| 95 |
# emerge -pv ">=app-misc/lcdproc-0.4.5" |
| 96 |
# emerge ">=app-misc/lcdproc-0.4.5" |
| 97 |
|
