high Nessus Plugin ID 134891
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


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


The remote host is running a version of the Gaia Operating System which is affected by multiple vulnerabilities involving the Linux Kernel's handling of TCP networking.
- It is possible to overflow the 16bit width of TCP_SKB_CB(skb)->tcp_gso_segs which could result in the system crashing resulting in a Denial of Service. (CVE-2019-11477)

- It is possible to fragment the TCP retransmission queue in tcp_fragment in the Linux Kernel when handling specific TCP Selective Acknowledgement sequences. This could be abused by an atacker to cause a Denial of Service. (CVE-2019-11478)

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


Apply the relevant patch and fix referenced in the vendor advisory.
