"According to its self-reported version, the remote SonicWall firewall is running a version of SonicOS that is affected
by multiple vulnerabilities:

  - Stack overflow in the parsing of IPv4 packets IP options. (CVE-2019-12256)

  - TCP Urgent Pointer = 0 leads to integer underflow (CVE-2019-12255)

  - TCP Urgent Pointer state confusion caused by malformed TCP AO option (CVE-2019-12260)

  - TCP Urgent Pointer state confusion during connect to a remote host (CVE-2019-12261)

  - TCP Urgent Pointer state confusion due to race condition (CVE-2019-12263)

  - Heap overflow in DHCP Offer/ACK parsing in ipdhcpc (CVE-2019-12257)

  - TCP connection DoS via malformed TCP options (CVE-2019-12258)

  - Handling of unsolicited Reverse ARP replies (Logical Flaw) (CVE-2019-12262)

  - Logical flaw in IPv4 assignment by the ipdhcpc DHCP client (CVE-2019-12264)

  - DoS via NULL dereference in IGMP parsing (CVE-2019-12259)

  - IGMP Information leak via IGMPv3 specific membership report (CVE-2019-12265)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
