New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote host is missing a vendor-supplied security patch.
DescriptionThe 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.
SolutionApply the relevant patch and fix referenced in the vendor advisory.
