Oracle Linux 6 / 7 : Unbreakable Enterprise kernel (ELSA-2015-3003)

high Nessus Plugin ID 81100

Synopsis

The remote Oracle Linux host is missing one or more security updates.

Description

The remote Oracle Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2015-3003 advisory.

- The sctp_process_param function in net/sctp/sm_make_chunk.c in the SCTP implementation in the Linux kernel before 3.17.4, when ASCONF is used, allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) via a malformed INIT chunk. (CVE-2014-7841)

- The SMB2_tcon function in fs/cifs/smb2pdu.c in the Linux kernel before 3.16.3 allows remote CIFS servers to cause a denial of service (NULL pointer dereference and client system crash) or possibly have unspecified other impact by deleting the IPC$ share during resolution of DFS referrals. (CVE-2014-7145)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
