Synopsis: CVE-2020-28374 can now be patched using Ksplice
CVEs: CVE-2020-28374

Users with Oracle Linux Premier Support can now use Ksplice to patch
against the latest Oracle kernel update, CVE-2020-28374.


We recommend that all users of Ksplice Uptrack running UEKR4 4.1.12 on
OL6 and OL7 install these updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,
these updates will be installed automatically and you do not need to
take any action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y


* CVE-2020-28374: Access control bypass when reading or writing TCM devices.

Lack of validation against the session's list when matching a Target Core
Mod (TCM) device during an eXtended COPY (XCOPY) operation leads to access
control bypass.  Attackers with access to one device could read and write
from/to other devices they should not have access to.
