Synopsis |
16 |
======== |
17 |
|
18 |
uw-imap is vulnerable to remote overflow of a buffer in the IMAP server |
19 |
leading to execution of arbitrary code. |
20 |
|
21 |

Description |
35 |
=========== |
36 |
|
37 |
Improper bounds checking of user supplied data while parsing IMAP |
38 |
mailbox names can lead to overflowing the stack buffer. |
39 |
|
40 |
Impact |
41 |
====== |
42 |
|
43 |
Successful exploitation requires an authenticated IMAP user to request |
44 |
a malformed mailbox name. This can lead to execution of arbitrary code |
45 |
with the permissions of the IMAP server. |
46 |
|
47 |
Workaround |
48 |
========== |
49 |
|
50 |
There are no known workarounds at this time. |
51 |
|
52 |
Resolution |
53 |
========== |
54 |
|
55 |
All uw-imap users should upgrade to the latest version: |
56 |
|
57 |
# emerge --sync |
58 |
# emerge --ask --oneshot --verbose ">=net-mail/uw-imap-2004g" |
