Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
A buffer overflow in zoo may be exploited to execute arbitrary when |
| 19 |
creating archives of specially crafted directories and files. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |

| 25 |

Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 app-arch/zoo < 2.10-r2 >= 2.10-r2 |
| 34 |
|
| 35 |
Description |
| 36 |
=========== |
| 37 |
|
| 38 |
zoo is vulnerable to a new buffer overflow due to insecure use of the |
| 39 |
strcpy() function when trying to create an archive from certain |
| 40 |
directories or filenames. |
| 41 |
|
| 42 |
Impact |
| 43 |
====== |
| 44 |
|
| 45 |
An attacker could exploit this issue by enticing a user to create a zoo |
| 46 |
archive of specially crafted directories and filenames, possibly |
| 47 |
leading to the execution of arbitrary code with the rights of the user |
| 48 |
running zoo. |
| 49 |
|
| 50 |
Workaround |
| 51 |
========== |
| 52 |
|
| 53 |
There is no known workaround at this time. |
| 54 |
|
| 55 |
Resolution |
| 56 |
========== |
| 57 |
|
| 58 |
All zoo users should upgrade to the latest version: |
| 59 |
|
| 60 |
# emerge --sync |
| 61 |
# emerge --ask --oneshot --verbose ">=app-arch/zoo-2.10-r2" |
| 62 |
|
