Description

The remote OracleVM system is missing necessary patches to address critical security updates :

  • nfsd: check for oversized NFSv2/v3 arguments (J. Bruce Fields) [Orabug: 26366024] (CVE-2017-7645)

  • dm mpath: allow ioctls to trigger pg init (Mikulas Patocka) [Orabug: 25645229]

  • xen/manage: Always freeze/thaw processes when suspend/resuming (Ross Lagerwall) [Orabug: 25795530]

  • lpfc cannot establish connection with targets that send PRLI under P2P mode (Joe Jin) [Orabug: 25955028]

  • nvme: Handle PM1725 HIL reset (Martin K. Petersen) [Orabug: 26277602]

  • dccp/tcp: do not inherit mc_list from parent (Eric Dumazet) [Orabug: 26108573] (CVE-2017-8890)

  • cifs: adjust sequence number downward after signing NT_CANCEL request (Albert Barbe)

  • nfsd: stricter decoding of write-like NFSv2/v3 ops (J. Bruce Fields) [Orabug: 25986995] (CVE-2017-7895)
