15 Synopsis
16 ========
17
18 libwmf bundles an old GD version which contains a "use-after-free"
19 vulnerability.
20
21 Background
22 ==========
23
24 libwmf is a library for converting WMF files.
25
26 Affected packages
27 =================
28
29 -------------------------------------------------------------------
30 Package / Vulnerable / Unaffected
31 -------------------------------------------------------------------
32 1 media-libs/libwmf < 0.2.8.4-r3 >= 0.2.8.4-r3
33
34 Description
35 ===========
36
37 The embedded fork of the GD library introduced a "use-after-free"
38 vulnerability in a modification which is specific to libwmf.
39
40 Impact
41 ======
42
43 A remote attacker could entice a user to open a specially crafted WMF
44 file, possibly resulting in the execution of arbitrary code with the
45 privileges of the user running the application, or a Denial of Service.
46
47 Workaround
48 ==========
49
50 There is no known workaround at this time.
51
52 Resolution
53 ==========
54
55 All libwmf users should upgrade to the latest version which no longer
56 builds the GD library:
57
58 # emerge --sync
59 # emerge --ask --oneshot --verbose ">=media-libs/libwmf-0.2.8.4-r3"
