Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Syslog-ng does not properly initialize its chroot jail allowing for an |
| 19 |
escape if a separate vulnerability in Syslog-ng is exploited. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Syslog-ng is a flexible and scalable system logger. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 app-admin/syslog-ng < 2.1.3 *>= 2.0.10 |
| 33 |
>= 2.1.3 |
| 34 |
|
| 35 |
Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Florian Grandel reported that Syslog-ng does not call chdir() before |
| 39 |
chroot() which leads to an inherited file descriptor to the current |
| 40 |
working directory. |
| 41 |
|
| 42 |
Impact |
| 43 |
====== |
| 44 |
|
| 45 |
A local attacker might exploit a separate vulnerability in Syslog-ng |
| 46 |
and use this vulnerability to escape the chroot jail. |
| 47 |
|
| 48 |
Workaround |
| 49 |
========== |
| 50 |
|
| 51 |
There is no known workaround at this time. |
| 52 |
|
| 53 |
Resolution |
| 54 |
========== |
| 55 |
|
| 56 |
All Syslog-ng 2.0 users should upgrade to the latest version: |
| 57 |
|
| 58 |
# emerge --sync |
| 59 |
# emerge --ask --oneshot --verbose ">=app-admin/syslog-ng-2.0.10" |
| 60 |
|
| 61 |
