15 | Synopsis |
16 | ======== |
17 | |
18 | The Cyrus IMAP Server contains multiple vulnerabilities which could |
19 | lead to remote execution of arbitrary code. |
20 | |
21 | Background |
22 | ========== |
23 | |
24 | The Cyrus IMAP Server is an efficient, highly-scalable IMAP e-mail |
25 | server. |
26 | |
27 | Affected packages |
28 | ================= |
29 | |
30 | ------------------------------------------------------------------- |
31 | Package / Vulnerable / Unaffected |
32 | ------------------------------------------------------------------- |
33 | 1 net-mail/cyrus-imapd < 2.2.10 >= 2.2.10 |
34 | |
35 | Description |
36 | =========== |
37 | |
38 | Multiple vulnerabilities have been discovered in the argument parsers |
39 | of the 'partial' and 'fetch' commands of the Cyrus IMAP Server |
40 | (CAN-2004-1012, CAN-2004-1013). There are also buffer overflows in the |
41 | 'imap magic plus' code that are vulnerable to exploitation as well |
42 | (CAN-2004-1011, CAN-2004-1015). |
43 | |
44 | Impact |
45 | ====== |
46 | |
47 | An attacker can exploit these vulnerabilities to execute arbitrary code |
48 | with the rights of the user running the Cyrus IMAP Server. |
49 | |
50 | Workaround |
51 | ========== |
52 | |
53 | There is no known workaround at this time. |
54 | |
55 | Resolution |
56 | ========== |
57 | |
58 | All Cyrus-IMAP Server users should upgrade to the latest version: |
59 | |
60 | # emerge --sync |
61 | # emerge --ask --oneshot --verbose ">=net-mail/cyrus-imapd-2.2.10" |
