| <p> |
| Matt Lewis of Google reported multiple integer overflows in the |
| libsvn_delta library, possibly leading to heap-based buffer overflows. |
| </p> |
| </description> |
| <impact type="high"> |
| <p> |
| A remote attacker with commit access could exploit this vulnerability |
| by sending a specially crafted commit to a Subversion server, or a |
| remote attacker could entice a user to check out or update a repository |
| from a malicious Subversion server, possibly resulting in the execution |
| of arbitrary code with the privileges of the user running the server or |
| client. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All Subversion users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=dev-util/subversion-1.6.4"</code> |
