Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
zip contains a buffer overflow when creating a ZIP archive of files |
| 19 |
with very long path names. This could lead to the execution of |
| 20 |
arbitrary code. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
zip is a compression and file packaging utility. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |
| 29 |
|
| 30 |
------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 app-arch/zip <= 2.3-r3 >= 2.3-r4 |
| 34 |
|
| 35 |
Description |
| 36 |
=========== |
| 37 |
|
| 38 |
zip does not check the resulting path length when doing recursive |
| 39 |
folder compression. |
| 40 |
|
| 41 |
Impact |
| 42 |
====== |
| 43 |
|
| 44 |
An attacker could exploit this by enticing another user or web |
| 45 |
application to create an archive including a specially-crafted path |
| 46 |
name, potentially resulting in the execution of arbitrary code with the |
| 47 |
permissions of the user running zip. |
| 48 |
|
| 49 |
Workaround |
| 50 |
========== |
| 51 |
|
| 52 |
There is no known workaround at this time. |
| 53 |
|
| 54 |
Resolution |
| 55 |
========== |
| 56 |
|
| 57 |
All zip users should upgrade to the latest version: |
| 58 |
|
| 59 |
# emerge --sync |
| 60 |
# emerge --ask --oneshot --verbose ">=app-arch/zip-2.3-r4" |
| 61 |
|
| 62 |
