Synopsis |
| 19 |
======== |
| 20 |
|
| 21 |
Python 2.2 has a vulnerability in DNS handling when IPV6 is disabled |
| 22 |
and a malformed IPV6 address is encountered by getaddrinfo(). |
| 23 |
|
| 24 |
Background |
| 25 |
========== |
| 26 |
|
| 27 |
Python is an interpreted, interactive, object-oriented, cross-platform |
| 28 |
programming language. |
| 29 |
|
| 30 |
Affected packages |
| 31 |
================= |
| 32 |
|
| 33 |
------------------------------------------------------------------- |
| 34 |
Package / Vulnerable / Unaffected |
| 35 |
------------------------------------------------------------------- |
| 36 |
1 dev-lang/python < 2.2.2 >= 2.2.2 |
| 37 |
< 2.2 |
| 38 |
|
| 39 |
Description |
| 40 |
=========== |
| 41 |
|
| 42 |
If IPV6 is disabled in Python 2.2, getaddrinfo() is not able to handle |
| 43 |
IPV6 DNS requests properly and a buffer overflow occurs. |
| 44 |
|
| 45 |
Impact |
| 46 |
====== |
| 47 |
|
| 48 |
An attacker can execute arbitrary code as the user running python. |
| 49 |
|
| 50 |
Workaround |
| 51 |
========== |
| 52 |
|
| 53 |
Users with IPV6 enabled are not affected by this vulnerability. |
| 54 |
|
| 55 |
Resolution |
| 56 |
========== |
| 57 |
|
| 58 |
All Python 2.2 users should upgrade to the latest version: |
| 59 |
|
| 60 |
# emerge sync |
| 61 |
|
| 62 |
# emerge -pv ">=dev-lang/python-2.2.2" |
| 63 |
# emerge ">=dev-lang/python-2.2.2" |
| 64 |
|
| 65 |
