15 Synopsis
16 ========
17
18 A vulnerability has been discovered in KVIrc, allowing for the remote
19 execution of arbitrary code.
20
21 Background
22 ==========
23
24 KVIrc is a free portable IRC client based on Qt.
25
26 Affected packages
27 =================
28
29 -------------------------------------------------------------------
30 Package / Vulnerable / Unaffected
31 -------------------------------------------------------------------
32 1 net-irc/kvirc < 3.2.6_pre20070714 >= 3.2.6_pre20070714
33
34 Description
35 ===========
36
37 Stefan Cornelius from Secunia Research discovered that the
38 "parseIrcUrl()" function in file src/kvirc/kernel/kvi_ircurl.cpp does
39 not properly sanitise parts of the URI when building the command for
40 KVIrc's internal script system.
41
42 Impact
43 ======
44
45 A remote attacker could entice a user to open a specially crafted
46 irc:// URI, possibly leading to the remote execution of arbitrary code
47 with the privileges of the user running KVIrc. Successful exploitation
48 requires that KVIrc is registered as the default handler for irc:// or
49 similar URIs.
50
51 Workaround
52 ==========
53
54 There is no known workaround at this time.
55
56 Resolution
57 ==========
58
59 All KVIrc users should upgrade to the latest version:
60
61 # emerge --sync
62 # emerge --ask --oneshot --verbose ">=net-irc/kvirc-3.2.6_pre20070714"
