Synopsis:          Important: kernel security and bug fix update
Advisory ID:       SLSA-2017:2473-1
Issue Date:        2017-08-15
CVE Numbers:       CVE-2017-7533
--

Security Fix(es):

* A race condition was found in the Linux kernel, present since v3.14-rc1
through v4.12. The race happens between threads of inotify_handle_event()
and vfs_rename() while running the rename operation against the same file.
As a result of the race the next slab data or the slab's free list pointer
can be corrupted with attacker-controlled data. (CVE-2017-7533, Important)

Bug Fix(es):

* Previously, direct I/O read operations going past EOF returned an
invalid error number, instead of reading 0 bytes and returning success, if
these operations were in same XFS block with EOF. Consequently, creating
multiple VMs from a Scientific Linux 7.4 template caused all the VMs to
become unresponsive in the 'Image Locked' state. This update fixes the
direct I/O feature of the file system, and VMs created from a Scientific
Linux 7.4 template now work as expected.

* This kernel is signed with the new Secure Boot key.
