A vulnerability has been found and corrected in subversion:
  Multiple integer overflows in the libsvn_delta library in Subversion
  before 1.5.7, and 1.6.x before 1.6.4, allow remote authenticated users
  and remote Subversion servers to execute arbitrary code via an svndiff
  stream with large windows that trigger a heap-based buffer overflow,
  a related issue to CVE-2009-2412 (CVE-2009-2411).
  This update provides a solution to this vulnerability and in turn
  upgrades subversion where possible to provide additional features
  and upstream bugfixes and adds required dependencies where needed.
