15 Synopsis
16 ========
17
18 Mozilla Firefox 1.0.2 fixes new security vulnerabilities, including the
19 remote execution of arbitrary code through malicious GIF images or

21
22 Background
23 ==========

40 Description
41 ===========
42
43 The following vulnerabilities were found and fixed in Mozilla Firefox:
44
45 * Mark Dowd from ISS X-Force reported an exploitable heap overrun in
46 the GIF processing of obsolete Netscape extension 2 (CAN-2005-0399)
47
48 * Kohei Yoshino discovered that a page bookmarked as a sidebar could
49 bypass privileges control (CAN-2005-0402)
50
51 * Michael Krax reported a new way to bypass XUL security restrictions
52 through drag-and-drop of items like scrollbars (CAN-2005-0401)
53
54 Impact
55 ======
56
57 * The GIF heap overflow could be triggered by a malicious GIF image
58 that would end up executing arbitrary code with the rights of the
59 user running Firefox
60
61 * By tricking the user into bookmarking a malicious page as a
62 Sidebar, a remote attacker could potentially execute arbitrary code
63 with the rights of the user running the browser
64
65 * By setting up a malicious website and convincing users to obey very
66 specific drag-and-drop instructions, attackers may leverage
67 drag-and-drop features to bypass XUL security restrictions, which
68 could be used as a stepping stone to exploit other vulnerabilities
69
70 Workaround
71 ==========
72
73 There is no known workaround at this time.
74
75 Resolution
76 ==========
77
78 All Mozilla Firefox users should upgrade to the latest version:
79
80 # emerge --sync
81 # emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-1.0.2"
82
83 All Mozilla Firefox binary users should upgrade to the latest version:
84
85 # emerge --sync
86 # emerge --ask --oneshot --verbose
87 ">=www-client/mozilla-firefox-bin-1.0.2"
