Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Insecure permission handling in maildrop might allow local attackers to |
| 19 |
elevate their privileges. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
maildrop is the mail filter/mail delivery agent that is used by the |
| 25 |
Courier Mail Server. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |
| 29 |
|
| 30 |
------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 mail-filter/maildrop < 2.4.2 >= 2.4.2 |
| 34 |
|
| 35 |
Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Christoph Anton Mitterer reported that maildrop does not properly drop |
| 39 |
its privileges when run as root. |
| 40 |
|
| 41 |
Impact |
| 42 |
====== |
| 43 |
|
| 44 |
A local attacker could create a specially crafted .mailfilter file, |
| 45 |
possibly leading to the execution of arbitrary commands with the "root" |
| 46 |
group privileges. NOTE: Successful exploitation requires that maildrop |
| 47 |
is run as root with the -d option. |
| 48 |
|
| 49 |
Workaround |
| 50 |
========== |
| 51 |
|
| 52 |
There is no known workaround at this time. |
| 53 |
|
| 54 |
Resolution |
| 55 |
========== |
| 56 |
|
| 57 |
All maildrop users should upgrade to the latest version: |
| 58 |
|
| 59 |
# emerge --sync |
| 60 |
# emerge --ask --oneshot --verbose ">=mail-filter/maildrop-2.4.2" |
| 61 |
|
