| 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. |

| 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" |
