| <p> |
| Poppler is a cross-platform PDF rendering library originally based on |
| Xpdf. |
| </p> |
| </background> |
| <description> |
| <p> |
| Poppler and Xpdf are vulnerable to an integer overflow in the |
| StreamPredictor::StreamPredictor function, and a stack overflow in the |
| StreamPredictor::getNextLine function. The original vulnerability was |
| discovered by Maurycy Prodeus. Note: Gentoo's version of Xpdf is |
| patched to use the Poppler library, so the update to Poppler will also |
| fix Xpdf. |
| </p> |
| </description> |
| <impact type="normal"> |
| <p> |
| By enticing a user to view a specially crafted program with a |
| Poppler-based PDF viewer such as Gentoo's Xpdf, Epdfview, or Evince, a |
| remote attacker could cause an overflow, potentially resulting in the |
| execution of arbitrary code with the privileges of the user running the |
| application. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All Poppler users should upgrade to the latest version of Poppler: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=app-text/poppler-0.5.4-r2"</code> |
