| <p> |
| Subversion is a version control system intended to eventually replace |
| CVS. Like CVS, it has an optional client-server architecture (where the |
| server can be an Apache server running mod_svn, or an ssh program as in |
| CVS's :ext: method). In addition to supporting the features found in |
| CVS, Subversion also provides support for moving and copying files and |
| directories. |

| <description> |
| <p> |
| All releases of Subversion prior to 1.0.3 have a vulnerability in the |
| date-parsing code. This vulnerability may allow denial of service or |
| arbitrary code execution as the Subversion user. Both the client and |
| server are vulnerable, and write access is NOT required to the server's |
| repository. |
| </p> |
| </description> |
| <impact type="normal"> |
| <p> |
| All servers and clients are vulnerable. Specifically, clients that |
| allow other users to write to administrative files in a working copy |
| may be exploited. Additionally all servers (whether they are httpd/DAV |
| or svnserve) are vulnerable. Write access to the server is not |
| required; public read-only Subversion servers are also exploitable. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. All users are encouraged to |
| upgrade to the latest available version. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All Subversion users should upgrade to the latest stable version: |
| </p> |
| <code> |
| # emerge sync |
| |
| # emerge -pv ">=dev-util/subversion-1.0.3" |
| # emerge ">=dev-util/subversion-1.0.3"</code> |
| </resolution> |
