15 Synopsis
16 ========
17
18 Gaim is vulnerable to a buffer overflow which could lead to the
19 execution of arbitrary code or to a Denial of Service.
20
21 Background
22 ==========
23
24 Gaim is a full featured instant messaging client which handles a
25 variety of instant messaging protocols.
26
27 Affected packages
28 =================
29
30 -------------------------------------------------------------------
31 Package / Vulnerable / Unaffected
32 -------------------------------------------------------------------
33 1 net-im/gaim < 1.5.0 >= 1.5.0
34
35 Description
36 ===========
37
38 Brandon Perry discovered that Gaim is vulnerable to a heap-based buffer
39 overflow when handling away messages (CAN-2005-2103). Furthermore,
40 Daniel Atallah discovered a vulnerability in the handling of file
41 transfers (CAN-2005-2102).
42
43 Impact
44 ======
45
46 A remote attacker could create a specially crafted away message which,
47 when viewed by the target user, could lead to the execution of
48 arbitrary code. Also, an attacker could send a file with a non-UTF8
49 filename to a user, which would result in a Denial of Service.
50
51 Workaround
52 ==========
53
54 There is no known workaround at this time.
55
56 Resolution
57 ==========
58
59 All Gaim users should upgrade to the latest version:
60
61 # emerge --sync
62 # emerge --ask --oneshot --verbose ">=net-im/gaim-1.5.0"
