Synopsis |
16 |
======== |
17 |
|
18 |
SpamAssassin, when running with certain options, could allow local or |
19 |
even remote attackers to execute arbitrary commands, possibly as the |
20 |
root user. |
21 |
|
22 |
Background |
23 |
========== |
24 |
|
25 |
SpamAssassin is an extensible email filter used to identify junk email. |
26 |
spamd is the daemonized version of SpamAssassin. |
27 |
|
28 |
Affected packages |
29 |
================= |
30 |
|
31 |
------------------------------------------------------------------- |
32 |
Package / Vulnerable / Unaffected |
33 |
------------------------------------------------------------------- |
34 |
1 mail-filter/spamassassin < 3.1.3 >= 3.1.3 |
35 |
|
36 |
Description |
37 |
=========== |
38 |
|
39 |
When spamd is run with both the "--vpopmail" (-v) and "--paranoid" (-P) |
40 |
options, it is vulnerable to an unspecified issue. |
41 |
|
42 |
Impact |
43 |
====== |
44 |
|
45 |
With certain configuration options, a local or even remote attacker |
46 |
could execute arbitrary code with the rights of the user running spamd, |
47 |
which is root by default, by sending a crafted message to the spamd |
48 |
daemon. Furthermore, the attack can be remotely performed if the |
49 |
"--allowed-ips" (-A) option is present and specifies non-local |
50 |
adresses. Note that Gentoo Linux is not vulnerable in the default |
51 |
configuration. |
52 |
|
53 |
Workaround |
54 |
========== |
55 |
|
56 |
Don't use both the "--paranoid" (-P) and the "--vpopmail" (-v) options. |
57 |
|
58 |
Resolution |
59 |
========== |
60 |
|
61 |
All SpamAssassin users should upgrade to the latest version: |
62 |
|
63 |
# emerge --sync |
64 |
# emerge --ask --oneshot --verbose ">=mail-filter/spamassassin-3.1.3" |
65 |
|
