Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Two vulnerabilities have been discovered in GNU cpio: |
| 38 |
|
| 39 |
* The list_file function in GNU cpio contains a heap-based buffer |
| 40 |
overflow vulnerability (CVE-2014-9112) |
| 41 |
* A directory traversal vulnerability has been found in GNU cpio |
| 42 |
(CVE-2015-1197) |
| 43 |
|
| 44 |
Impact |
| 45 |
====== |
| 46 |
|
| 47 |
A remote attacker may be able to entice a user to open a specially |
| 48 |
crafted archive using GNU cpio, possibly resulting in execution of |
| 49 |
arbitrary code, a Denial of Service condition, or overwriting arbitrary |
| 50 |
files. |
| 51 |
|
| 52 |
Workaround |
| 53 |
========== |
| 54 |
|
| 55 |
There is no known workaround at this time. |
| 56 |
|
| 57 |
Resolution |
| 58 |
========== |
| 59 |
|
| 60 |
All GNU cpio users should upgrade to the latest version: |
| 61 |
|
| 62 |
# emerge --sync |
| 63 |
# emerge --ask --oneshot --verbose ">=app-arch/cpio-2.11-r3" |
| 64 |
