Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple vulnerabilities in bip might allow remote unauthenticated |
| 19 |
attackers to cause a Denial of Service or possibly execute arbitrary |
| 20 |
code. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
bip is a multi-user IRC proxy with SSL support. |
| 26 |
|
| 27 |

Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Multiple vulnerabilities have been discovered in bip: |
| 39 |
|
| 40 |
* Uli Schlachter reported that bip does not properly handle invalid |
| 41 |
data during authentication, resulting in a daemon crash |
| 42 |
(CVE-2010-3071). |
| 43 |
* Julien Tinnes reported that bip does not check the number of open |
| 44 |
file descriptors against FD_SETSIZE, resulting in a stack buffer |
| 45 |
overflow (CVE-2012-0806). |
| 46 |
|
| 47 |
Impact |
| 48 |
====== |
| 49 |
|
| 50 |
A remote attacker could exploit these vulnerabilities to execute |
| 51 |
arbitrary code with the privileges of the user running the bip daemon, |
| 52 |
or cause a Denial of Service condition. |
| 53 |
|
| 54 |
Workaround |
| 55 |
========== |
| 56 |
|
| 57 |
There is no known workaround at this time. |
| 58 |
|
| 59 |
Resolution |
| 60 |
========== |
| 61 |
|
| 62 |
All bip users should upgrade to the latest version: |
| 63 |
|
| 64 |
# emerge --sync |
| 65 |
# emerge --ask --oneshot --verbose ">=net-irc/bip-0.8.8-r1" |
| 66 |
|
| 67 |
NOTE: The CVE-2010-3071 flaw was already corrected in an earlier |
| 68 |
version of bip and is included in this advisory for completeness. |
