Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
The zziplib library contains a buffer overflow vulnerability that could |
| 19 |
lead to user-assisted remote execution of arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |

Description |
| 36 |
=========== |
| 37 |

| 41 |
Impact |
| 42 |
====== |
| 43 |
|
| 44 |
A remote attacker could entice a user to run a zziplib function with an |
| 45 |
overly long string as an argument which would trigger the buffer |
| 46 |
overflow and may lead to the execution of arbitrary code. |
| 47 |
|
| 48 |
Workaround |
| 49 |
========== |
| 50 |
|
| 51 |
There is no known workaround at this time. |
| 52 |
|
| 53 |
Resolution |
| 54 |
========== |
| 55 |
|
| 56 |
All zziplib users should upgrade to the latest version: |
| 57 |
|
| 58 |
# emerge --sync |
| 59 |
# emerge --ask --oneshot --verbose ">=dev-libs/zziplib-0.13.49" |
