Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
eix has an insecure temporary file creation vulnerability, potentially |
| 19 |
allowing a local user to overwrite arbitrary files. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
eix is a small utility for searching ebuilds with indexing for fast |
| 25 |
results. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |

------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 app-portage/eix < 0.5.0_pre2 >= 0.5.0_pre2 |
| 34 |
*>= 0.3.0-r2 |
| 35 |
|
| 36 |
Description |
| 37 |
=========== |
| 38 |
|
| 39 |
Eric Romang discovered that eix creates a temporary file with a |
| 40 |
predictable name. eix creates a temporary file in /tmp/eix.*.sync where |
| 41 |
* is the process ID of the shell running eix. |
| 42 |
|
| 43 |
Impact |
| 44 |
====== |
| 45 |
|
| 46 |
A local attacker can watch the process list and determine the process |
| 47 |
ID of the shell running eix while the "emerge --sync" command is |
| 48 |
running, then create a link from the corresponding temporary file to a |
| 49 |
system file, which would result in the file being overwritten with the |
| 50 |
rights of the user running the application. |
| 51 |
|
| 52 |
Workaround |
| 53 |
========== |
| 54 |
|
| 55 |
There is no known workaround at this time. |
| 56 |
|
| 57 |
Resolution |
| 58 |
========== |
| 59 |
|
| 60 |
All eix users should upgrade to the latest version: |
| 61 |
|
| 62 |
# emerge --sync |
| 63 |
# emerge --ask --oneshot --verbose app-portage/eix |
| 64 |
|
