| <title>Xpdf, CUPS: Multiple integer overflows</title> |
| <synopsis> |
| Multiple integer overflows were discovered in Xpdf, potentially resulting |
| in execution of arbitrary code upon viewing a malicious PDF file. CUPS |
| includes Xpdf code and therefore is vulnerable to the same issues. |

| Xpdf is an open source viewer for Portable Document Format (PDF) files. The |
| Common UNIX Printing System (CUPS) is a cross-platform print spooler that |
| includes some Xpdf code. |

| <impact type="normal"> |
| <p> |
| An attacker could entice an user to open a specially-crafted PDF file, |
| potentially resulting in execution of arbitrary code with the rights of the |
| user running Xpdf. By enticing an user to directly print the PDF file to a |
| CUPS printer, an attacker could also crash the CUPS spooler or execute |
| arbitrary code with the rights of the CUPS spooler, which is usually the |
| "lp" user. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All Xpdf users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=app-text/xpdf-3.00-r5"</code> |
| <p> |
| All CUPS users should also upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=net-print/cups-1.1.20-r5"</code> |
