15 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 Background
22 ==========
23
24 uw-imap is the University of Washington's IMAP and POP server daemons.
25
26 Affected packages
27 =================
28
29 -------------------------------------------------------------------
30 Package / Vulnerable / Unaffected
31 -------------------------------------------------------------------
32 1 net-mail/uw-imap < 2004g >= 2004g
33
34 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"
