15 | Synopsis |
16 | ======== |
17 | |
18 | POV-Ray includes a version of libpng that might allow for the execution |
19 | of arbitrary code when reading a specially crafted PNG file |
20 | |
21 | Background |
22 | ========== |
23 | |
24 | POV-Ray is a well known open-source ray tracer. |
25 | |
26 | Affected packages |
27 | ================= |
28 | |
29 | ------------------------------------------------------------------- |
30 | Package / Vulnerable / Unaffected |
31 | ------------------------------------------------------------------- |
32 | 1 media-gfx/povray < 3.6.1-r4 >= 3.6.1-r4 |
33 | |
34 | Description |
35 | =========== |
36 | |
37 | POV-Ray uses a statically linked copy of libpng to view and output PNG |
38 | files. The version shipped with POV-Ray is vulnerable to CVE-2008-3964, |
39 | CVE-2008-1382, CVE-2006-3334, CVE-2006-0481, CVE-2004-0768. A bug in |
40 | POV-Ray's build system caused it to load the old version when your |
41 | installed copy of libpng was >=media-libs/libpng-1.2.10. |
42 | |
43 | Impact |
44 | ====== |
45 | |
46 | An attacker could entice a user to load a specially crafted PNG file as |
47 | a texture, resulting in the execution of arbitrary code with the |
48 | permissions of the user running the application. |
49 | |
50 | Workaround |
51 | ========== |
52 | |
53 | There is no known workaround at this time. |
54 | |
55 | Resolution |
56 | ========== |
57 | |
58 | All POV-Ray users should upgrade to the latest version: |
59 | |
60 | # emerge --sync |
61 | # emerge --ask --oneshot --verbose ">=media-gfx/povray-3.6.1-r4" |
