Description Stefan Behte (RETIRED) gentoo-dev Security 2009-07-13 21:51:18 UTC 
CVE-2009-1935 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-1935):
  Integer overflow in the pipe_build_write_buffer function
  (sys/kern/sys_pipe.c) in the direct write optimization feature in the
  pipe implementation in FreeBSD 7.1 through 7.2 and 6.3 through 6.4
  allows local users to bypass virtual-to-physical address lookups and
  read sensitive information in memory pages via unspecified vectors.
