The remote Scientific Linux host is missing one or more security
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.
