15 Synopsis
16 ========
17
18 There are several bugs in Qt's image-handling code which could lead to
19 crashes or arbitrary code execution.
20
21 Background
22 ==========
23
24 Qt is a cross-platform GUI toolkit used by KDE.
25
26 Affected packages
27 =================
28
29 -------------------------------------------------------------------
30 Package / Vulnerable / Unaffected
31 -------------------------------------------------------------------
32 1 x11-libs/qt <= 3.3.2 >= 3.3.3
33
34 Description
35 ===========
36
37 There are several unspecified bugs in the QImage class which may cause
38 crashes or allow execution of arbitrary code as the user running the Qt
39 application. These bugs affect the PNG, XPM, BMP, GIF and JPEG image
40 types.
41
42 Impact
43 ======
44
45 An attacker may exploit these bugs by causing a user to open a
46 carefully-constructed image file in any one of these formats. This may
47 be accomplished through e-mail attachments (if the user uses KMail), or
48 by simply placing a malformed image on a website and then convicing the
49 user to load the site in a Qt-based browser (such as Konqueror).
50
51 Workaround
52 ==========
53
54 There is no known workaround at this time. All users are encouraged to
55 upgrade to the latest available version of Qt.
56
57 Resolution
58 ==========
59
60 All Qt users should upgrade to the latest version:
61
62 # emerge sync
63
64 # emerge -pv ">=x11-libs/qt-3.3.3"
65 # emerge ">=x11-libs/qt-3.3.3"
