Synopsis |
| 17 |
======== |
| 18 |
|
| 19 |
An input validation vulnerability has been discovered in Horde-IMP. |
| 20 |
This only affects users of Internet Explorer. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
Horde-IMP is the Internet Messaging Program. It is written in PHP and |
| 26 |
provides webmail access to IMAP and POP3 accounts. |
| 27 |
|
| 28 |
Affected packages |
| 29 |
================= |
| 30 |
|
| 31 |
------------------------------------------------------------------- |
| 32 |
Package / Vulnerable / Unaffected |
| 33 |
------------------------------------------------------------------- |
| 34 |
1 net-www/horde-imp <= 3.2.4 >= 3.2.5 |
| 35 |
|
| 36 |
Description |
| 37 |
=========== |
| 38 |
|
| 39 |
Horde-IMP fails to properly sanitize email messages that contain |
| 40 |
malicious HTML or script code so that it is not safe for users of |
| 41 |
Internet Explorer when using the inline MIME viewer for HTML messages. |
| 42 |
|
| 43 |
Impact |
| 44 |
====== |
| 45 |
|
| 46 |
By enticing a user to read a specially crafted e-mail, an attacker can |
| 47 |
execute arbitrary scripts running in the context of the victim's |
| 48 |
browser. This could lead to a compromise of the user's webmail account, |
| 49 |
cookie theft, etc. |
| 50 |
|
| 51 |
Workaround |
| 52 |
========== |
| 53 |
|
| 54 |
Do not use Internet Explorer to access Horde-IMP. |
| 55 |
|
| 56 |
Resolution |
| 57 |
========== |
| 58 |
|
| 59 |
All Horde-IMP users should upgrade to the latest stable version: |
| 60 |
|
| 61 |
# emerge sync |
| 62 |
|
| 63 |
# emerge -pv ">=horde-imp-3.2.5" |
| 64 |
# emerge ">=horde-imp-3.2.5" |
| 65 |
|
