Synopsis |
16 |
======== |
17 |
|
18 |
Squirrelmail fails to properly sanitize user input, which could lead to |
19 |
a compromise of webmail accounts. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
SquirrelMail is a webmail package written in PHP. It supports IMAP and |
25 |

|
35 |
Description |
36 |
=========== |
37 |
|
38 |
SquirrelMail fails to properly sanitize certain strings when decoding |
39 |
specially-crafted headers. |
40 |
|
41 |
Impact |
42 |
====== |
43 |
|
44 |
By enticing a user to read a specially-crafted e-mail, an attacker can |
45 |
execute arbitrary scripts running in the context of the victim's |
46 |
browser. This could lead to a compromise of the user's webmail account, |
47 |
cookie theft, etc. |
48 |
|
49 |
Workaround |
50 |
========== |
51 |
|
52 |
There is no known workaround at this time. |
53 |
|
54 |
Resolution |
55 |
========== |
56 |
|
57 |
All SquirrelMail users should upgrade to the latest version: |
58 |
|
59 |
# emerge --sync |
60 |
# emerge --ask --oneshot --verbose ">=mail-client/squirrelmail-1.4.3a-r2" |
61 |
|
62 |
Note: Users with the vhosts USE flag set should manually use |
63 |
webapp-config to finalize the update. |
