Synopsis

The remote Oracle Linux host is missing a security update.

Description

The remote Oracle Linux 6 / 7 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2017-3579 advisory.

- The packet_set_ring function in net/packet/af_packet.c in the Linux kernel through 4.10.6 does not properly validate certain block-size data, which allows local users to cause a denial of service (integer signedness error and out-of-bounds write), or gain privileges (if the CAP_NET_RAW capability is held), via crafted system calls. (CVE-2017-7308)

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.
