Description Agostino Sarubbo gentoo-dev 2014-03-25 12:04:21 UTC 
CVE-2014-2038 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-2038):

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.
