====== |
| 45 |
|
| 46 |
An attacker could entice a user to process specially crafted regular |
| 47 |
expressions with Chicken, which could possibly lead to the execution of |
| 48 |
arbitrary code, a Denial of Service or the disclosure of sensitive |
| 49 |
information. |

|
| 51 |
Workaround |
| 52 |
========== |
| 53 |
|
| 54 |

| 55 |
|
| 56 |
Resolution |
| 57 |
========== |
| 58 |
|
| 59 |

| 60 |
|
| 61 |
# emerge --sync |
| 62 |
# emerge --ask --oneshot --verbose ">=dev-scheme/chicken-3.1.0" |
