** Description changed:

- [nfs: information leakage]
+ The nfs_can_extend_write function in fs/nfs/write.c in the Linux kernel
+ before 3.13.3 relies on a write delegation to extend a write operation
+ without a certain up-to-date verification, which allows local users to
+ obtain sensitive information from kernel memory in opportunistic
+ circumstances by writing to a file in an NFS filesystem and then reading
+ the same file.
  
  Break-Fix: c7559663e42f4294ffe31fe159da6b6a66b35d61
