The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:1854 advisory.

  • kernel: AIO interface didn’t use rw_verify_area() for checking mandatory locking on files and size of access (CVE-2012-6701)

  • kernel: AIO write triggers integer overflow in some protocols (CVE-2015-8830)

  • kernel: Null pointer dereference via keyctl (CVE-2016-8650)

  • kernel: ping socket / AF_LLC connect() sin_family race (CVE-2017-2671)

  • kernel: Race condition between multiple sys_perf_event_open() calls (CVE-2017-6001)

  • kernel: net/packet: overflow in check for priv area size (CVE-2017-7308)

  • kernel: Incorrect error handling in the set_mempolicy and mbind compat syscalls in mm/mempolicy.c (CVE-2017-7616)

  • kernel: mm subsystem does not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism (CVE-2017-7889)

  • kernel: Double free in the inet_csk_clone_lock function in net/ipv4/inet_connection_sock.c (CVE-2017-8890)

  • kernel: net: sctp_v6_create_accept_sk function mishandles inheritance (CVE-2017-9075)

  • kernel: net: IPv6 DCCP implementation mishandles inheritance (CVE-2017-9076)

  • kernel: net: tcp_v6_syn_recv_sock function mishandles inheritance (CVE-2017-9077)

  • kernel: memory leak when merging buffers in SCSI IO vectors (CVE-2017-12190)

  • kernel: vfs: BUG in truncate_inode_pages_range() and fuse client (CVE-2017-15121)

  • kernel: Race condition in drivers/md/dm.c:dm_get_from_kobject() allows local users to cause a denial of service (CVE-2017-18203)

  • kernel: a null pointer dereference in net/dccp/output.c:dccp_write_xmit() leads to a system crash (CVE-2018-1130)

  • hw: cpu: speculative store bypass (CVE-2018-3639)

  • kernel: Missing length check of payload in net/sctp/sm_make_chunk.c:_sctp_make_chunk() function allows denial of service (CVE-2018-5803)
