15 Synopsis
16 ========
17
18 Centericq does not properly handle communications with the LiveJournal
19 service, allowing for the remote execution of arbitrary code.
20
21 Background
22 ==========
23
24 Centericq is a text mode menu-driven and window-driven instant
25 messaging interface.
26
27 Affected packages
28 =================
29
30 -------------------------------------------------------------------
31 Package / Vulnerable / Unaffected
32 -------------------------------------------------------------------
33 1 net-im/centericq <= 4.21.0-r2 Vulnerable!
34 -------------------------------------------------------------------
35 NOTE: Certain packages are still vulnerable. Users should migrate
36 to another package if one is available or wait for the
37 existing packages to be marked stable by their
38 architecture maintainers.
39
40 Description
41 ===========
42
43 When interfacing with the LiveJournal service, Centericq does not
44 appropriately allocate memory for incoming data, in some cases creating
45 a buffer overflow.
46
47 Impact
48 ======
49
50 An attacker could entice a user to connect to an unofficial LiveJournal
51 server causing Centericq to read specially crafted data from the
52 server, which could lead to the execution of arbitrary code with the
53 rights of the user running Centericq.
54
55 Workaround
56 ==========
57
58 There is no known workaround at this time.
59
60 Resolution
61 ==========
62
63 Currently, Centericq is unmaintained. As such, Centericq has been
64 masked in Portage until it is again maintained.
65
66 # emerge --ask --verbose --unmerge "net-im/centericq"
