CUPS includes Xpdf code and therefore is vulnerable to the same issues. </synopsis> <product type="ebuild">Xpdf</product> <announced>2004-10-21</announced> <revised count="02">2004-11-06</revised> <bug>69662</bug> <access>remote</access> <affected> <package name="app-text/xpdf" auto="yes" arch="*"> <unaffected range="ge">3.00-r5</unaffected> <vulnerable range="le">3.00-r4</vulnerable> </package> <package name="net-print/cups" auto="yes" arch="*"> <unaffected range="ge">1.1.20-r5</unaffected> <vulnerable range="le">1.1.20-r4</vulnerable> </package> </affected> <background> <p> 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. </p> </background> <description> <p> Chris Evans discovered multiple integer overflow issues in Xpdf. </p> </description> <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> </resolution> <references> <uri link="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0888">CAN-2004-0888</uri> <uri link="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0889">CAN-2004-0889</uri> </references> <metadata tag="submitter" timestamp="2004-10-21T10:10:18Z"> koon </metadata> <metadata tag="bugReady" timestamp="2004-10-21T14:18:53Z"> koon </metadata> </glsa>
