Description |
35 |
=========== |
36 |
|
37 |
Multiple vulnerabilities were found in SquirrelMail: |
38 |
|
39 |
* Niels Teusink reported multiple input sanitation flaws in certain |
40 |
encrypted strings in e-mail headers, related to |
41 |
contrib/decrypt_headers.php, PHP_SELF and the query string (aka |
42 |
QUERY_STRING) (CVE-2009-1578). |
43 |
|
44 |
* Niels Teusink also reported that the map_yp_alias() function in |
45 |
functions/imap_general.php does not filter shell metacharacters in a |
46 |
username and that the original patch was incomplete (CVE-2009-1381, |
47 |
CVE-2009-1579). |
48 |
|
49 |
* Tomas Hoger discovered an unspecified session fixation |
50 |
vulnerability (CVE-2009-1580). |
51 |
|
52 |
* Luc Beurton reported that functions/mime.php does not protect the |
53 |
application's content from Cascading Style Sheets (CSS) positioning |
54 |
in HTML e-mail messages (CVE-2009-1581). |
55 |
|
56 |
Impact |
57 |
====== |
58 |
|
59 |
The vulnerabilities allow remote attackers to execute arbitrary code |
60 |
with the privileges of the user running the web server, to hijack web |
61 |
sessions via a crafted cookie, to spoof the user interface and to |
62 |
conduct Cross-Site Scripting and phishing attacks, via a specially |
63 |
crafted message. |
64 |
|
65 |
Workaround |
66 |
========== |
67 |
|
68 |
There is no known workaround at this time. |
69 |
|
70 |
Resolution |
71 |
========== |
72 |
|
73 |
All SquirrelMail users should upgrade to the latest version: |
74 |
|
75 |
# emerge --sync |
76 |
# emerge --ask --oneshot --verbose ">=mail-client/squirrelmail-1.4.19" |
