| <p> |
| ANTHRAX666 reported an insecure call to the sscanf() function in the |
| set_page_size() function in htmldoc/util.cxx. 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. |

| <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> |
