F5 Networks BIG-IP : Linux kernel vulnerability (K04107324)

high Nessus Plugin ID 184215

Language:

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

The version of F5 Networks BIG-IP installed on the remote host is prior to 13.1.4.1 / 14.1.4.2 / 15.1.4 / 16.0.1.2 / 16.1.0. It is, therefore, affected by a vulnerability as referenced in the K04107324 advisory.

 - An infinite loop issue was found in the vhost_net kernel module in Linux Kernel up to and including v5.1-rc6, while handling incoming packets in handle_rx(). It could occur if one end sends packets faster than the other end can process them. A guest user, maybe remote one, could use this flaw to stall the vhost_net kernel thread, resulting in a DoS scenario. (CVE-2019-3900)

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

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K04107324.
