15 Synopsis
16 ========
17
18 An error in Gajim causes invalid OpenSSL certificates to be accepted as
19 valid.
20
21 Background
22 ==========
23
24 Gajim is a Jabber/XMPP client which uses GTK+.
25
26 Affected packages
27 =================
28
29 -------------------------------------------------------------------
30 Package / Vulnerable / Unaffected
31 -------------------------------------------------------------------
32 1 net-im/gajim < 0.15.3-r1 >= 0.15.3-r1
33
34 Description
35 ===========
36
37 The _ssl_verify_callback() function in tls_nb.py does not properly
38 validate SSL certificates, causing any certificate to be accepted as
39 valid as long as the root CA is valid.
40
41 Impact
42 ======
43
44 A remote attacker might employ a specially crafted certificate to
45 conduct man-in-the-middle attacks on SSL connections and potentially
46 disclose sensitive information.
47
48 Workaround
49 ==========
50
51 There is no known workaround at this time.
52
53 Resolution
54 ==========
55
56 All Gajim users should upgrade to the latest version:
57
58 # emerge --sync
59 # emerge --ask --oneshot --verbose ">=net-im/gajim-0.15.3-r1"
