| 15 | Synopsis |
| 16 | ======== |
| 17 | |
| 18 | PDFlib is vulnerable to multiple overflows, which can potentially lead |
| 19 | to the execution of arbitrary code. |
| 20 | |
| 21 | Background |
| 22 | ========== |
| 23 | |
| 24 | PDFlib is a library providing functions to handle PDF files. It |
| 25 | includes a modified TIFF library used to process TIFF images. |
| 26 | |
| 27 | Affected packages |
| 28 | ================= |
| 29 | |
| 30 | ------------------------------------------------------------------- |
| 31 | Package / Vulnerable / Unaffected |
| 32 | ------------------------------------------------------------------- |
| 33 | 1 media-libs/pdflib < 5.0.4_p1 >= 5.0.4_p1 |
| 34 | |
| 35 | Description |
| 36 | =========== |
| 37 | |
| 38 | The TIFF library is subject to several known vulnerabilities (see GLSA |
| 39 | 200410-11). Most of these overflows also apply to PDFlib. |
| 40 | |
| 41 | Impact |
| 42 | ====== |
| 43 | |
| 44 | A remote attacker could entice a user or web application to process a |
| 45 | carefully crafted PDF file or TIFF image using a PDFlib-powered |
| 46 | program. This can potentially lead to the execution of arbitrary code |
| 47 | with the rights of the program processing the file. |
| 48 | |
| 49 | Workaround |
| 50 | ========== |
| 51 | |
| 52 | There is no known workaround at this time. |
| 53 | |
| 54 | Resolution |
| 55 | ========== |
| 56 | |
| 57 | All PDFlib users should upgrade to the latest version: |
| 58 | |
| 59 | # emerge --sync |
| 60 | # emerge --ask --oneshot --verbose ">=media-libs/pdflib-5.0.4_p1" |
