(Buffer overflow in Subversion)

    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.
  
Impact :

    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.
  
Workaround :

    There is no known workaround at this time. All users are encouraged to
    upgrade to the latest available version."
