15 Synopsis
16 ========
17
18 A buffer overflow in TMSNC might lead to the execution of arbitrary
19 code when processing an instant message.
20
21 Background
22 ==========
23
24 TMSNC is a Textbased client for the MSN instant messaging protocol.
25
26 Affected packages
27 =================
28
29 -------------------------------------------------------------------
30 Package / Vulnerable / Unaffected
31 -------------------------------------------------------------------
32 1 net-im/tmsnc <= 0.3.2-r1 Vulnerable!
33 -------------------------------------------------------------------
34 NOTE: Certain packages are still vulnerable. Users should migrate
35 to another package if one is available or wait for the
36 existing packages to be marked stable by their
37 architecture maintainers.
38
39 Description
40 ===========
41
42 Nico Golde reported a stack-based buffer overflow when processing a MSN
43 packet with a UBX command containing a large UBX payload length field.
44
45 Impact
46 ======
47
48 A remote attacker could send a specially crafted message, possibly
49 resulting in the execution of arbitrary code.
50
51 Workaround
52 ==========
53
54 There is no known workaround at this time.
55
56 Resolution
57 ==========
58
59 Since TMSNC is no longer maintained, we recommend that users unmerge
60 the vulnerable package and switch to another console-based MSN client
61 such as CenterIM or Pebrot:
62
63 # emerge --unmerge "net-im/tmsnc"
