Description Robert Buchholz (RETIRED) gentoo-dev 2009-03-22 22:26:47 UTC 
ecryptfs throughout 2.6.28 wrote sensitive kernel memory to files that could potentially be read by users.
Comment 1 Stefan Behte (RETIRED) gentoo-dev Security 2009-03-31 20:36:13 UTC 
CVE-2009-0787 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-0787):
  The ecryptfs_write_metadata_to_contents function in the eCryptfs
  functionality in the Linux kernel 2.6.28 before 2.6.28.9 uses an
  incorrect size when writing kernel memory to an eCryptfs file header,
  which triggers an out-of-bounds read and allows local users to obtain
  portions of kernel memory.
