Nico Golde of the Debian Security Team found two more insecure calls in the write_type1() function in htmldoc/ps-pdf.cxx and the htmlLoadFontWidths() function in htmldoc/htmllib.cxx. </p> </description> <impact type="normal"> <p> A remote attacker could entice a user to process a specially crafted HTML file using htmldoc, possibly resulting in the execution of arbitrary code with the privileges of the user running the application. NOTE: Additional vectors via specially crafted AFM font metric files do not cross trust boundaries, as the files can only be modified by privileged users. </p> </impact> <workaround> <p> There is no known workaround at this time. </p> </workaround> <resolution> <p> All HTMLDOC users should upgrade to the latest version: </p> <code> # emerge --sync # emerge --ask --oneshot --verbose ">=app-text/htmldoc-1.8.27-r1"</code> </resolution> <references> <uri link="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-3050">CVE-2009-3050</uri> </references> <metadata tag="requester" timestamp="2009-08-26T18:35:26Z"> a3li </metadata> <metadata tag="submitter" timestamp="2009-08-26T18:45:17Z"> a3li </metadata> <metadata tag="bugReady" timestamp="2009-09-06T09:53:24Z"> a3li </metadata> </glsa>
