Synopsis

The remote Oracle Linux host is missing a security update.

Description

The remote Oracle Linux 5 / 6 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2016-3652 advisory.

- The sctp_sf_ootb function in net/sctp/sm_statefuns.c in the Linux kernel before 4.8.8 lacks chunk-length checking for the first chunk, which allows remote attackers to cause a denial of service (out-of-bounds slab access) or possibly have unspecified other impact via crafted SCTP data. (CVE-2016-9555)

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.
