15 | Synopsis |
16 | ======== |
17 | |
18 | KPdf and KWord both include vulnerable Xpdf code to handle PDF files, |
19 | making them vulnerable to the execution of arbitrary code. |
20 | |
21 | Background |
22 | ========== |
23 | |
24 | KPdf is a KDE-based PDF viewer included in the kdegraphics package. |
25 | KWord is a KDE-based word processor also included in the koffice |
26 | package. |
27 | |
28 | Affected packages |
29 | ================= |
30 | |
31 | ------------------------------------------------------------------- |
32 | Package / Vulnerable / Unaffected |
33 | ------------------------------------------------------------------- |
34 | 1 kde-base/kdegraphics < 3.4.3-r3 >= 3.4.3-r3 |
35 | 2 kde-base/kpdf < 3.4.3-r3 >= 3.4.3-r3 |
36 | 3 app-office/koffice < 1.4.2-r6 >= 1.4.2-r6 |
37 | 4 app-office/kword < 1.4.2-r6 >= 1.4.2-r6 |
38 | ------------------------------------------------------------------- |
39 | 4 affected packages on all of their supported architectures. |

41 | |
42 | Description |
43 | =========== |
44 | |
45 | KPdf and KWord both include Xpdf code to handle PDF files. This Xpdf |
46 | code is vulnerable to several heap overflows (GLSA 200512-08) as well |
47 | as several buffer and integer overflows discovered by Chris Evans. |
48 | |
49 | Impact |
50 | ====== |
51 | |
52 | An attacker could entice a user to open a specially crafted PDF file |
53 | with Kpdf or KWord, potentially resulting in the execution of arbitrary |
54 | code with the rights of the user running the affected application. |
55 | |
56 | Workaround |
57 | ========== |
58 | |
59 | There is no known workaround at this time. |
60 | |
61 | Resolution |
62 | ========== |
63 | |
64 | All kdegraphics users should upgrade to the latest version: |
65 | |
66 | # emerge --sync |
67 | # emerge --ask --oneshot --verbose ">=kde-base/kdegraphics-3.4.3-r3" |
68 | |
69 | All Kpdf users should upgrade to the latest version: |
70 | |
71 | # emerge --sync |
72 | # emerge --ask --oneshot --verbose ">=kde-base/kpdf-3.4.3-r3" |
73 | |
74 | All KOffice users should upgrade to the latest version: |
75 | |
76 | # emerge --sync |
77 | # emerge --ask --oneshot --verbose ">=app-office/koffice-1.4.2-r6" |
78 | |
79 | All KWord users should upgrade to the latest version: |
80 | |
81 | # emerge --sync |
82 | # emerge --ask --oneshot --verbose ">=app-office/kword-1.4.2-r6" |
