CVE ID:	CVE-2008-3275
Description:	The (1) real_lookup and (2) __lookup_hash functions in fs/namei.c in the vfs implementation in the Linux kernel before 2.6.25.15 do not prevent creation of a child dentry for a deleted (aka S_DEAD) directory, which allows local users to cause a denial of service ("overflow" of the UBIFS orphan area) via a series of attempted file creations within deleted directories.
Test IDs:	1.3.6.1.4.1.25623.1.0.61594   1.3.6.1.4.1.25623.1.0.61436
