to extract files to an arbitrary directory. |
| 20 |
|
| 21 |

Description |
| 35 |
=========== |
| 36 |
|
| 37 |
A vulnerability has been found in cpio that can potentially allow a |
| 38 |
cpio archive to extract its files to an arbitrary directory of the |
| 39 |
creator's choice. |
| 40 |
|
| 41 |
Impact |
| 42 |
====== |
| 43 |
|
| 44 |
An attacker could create a malicious cpio archive which would create |
| 45 |
files in arbitrary locations on the victim's system. This issue could |
| 46 |
also be used in conjunction with a previous race condition |
| 47 |
vulnerability (CAN-2005-1111) to change permissions on files owned by |
| 48 |
the victim. |
| 49 |
|
| 50 |
Workaround |
| 51 |
========== |
| 52 |
|
| 53 |
There is no known workaround at this time. |
| 54 |
|
| 55 |
Resolution |
| 56 |
========== |
| 57 |
|
| 58 |
All cpio users should upgrade to the latest version: |
| 59 |
|
| 60 |
# emerge --sync |
| 61 |
# emerge --ask --oneshot --verbose ">=app-arch/cpio-2.6-r3" |
| 62 |
