According to the version of the open-iscsi package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerability :

  - An issue was discovered in uIP 1.0, as used in Contiki     3.0 and other products. The code that reassembles     fragmented packets fails to properly validate the total     length of an incoming packet specified in its IP     header, as well as the fragmentation offset value     specified in the IP header. By crafting a packet with     specific values of the IP header length and the     fragmentation offset, attackers can write into the .bss     section of the program (past the statically allocated     buffer that is used for storing the fragmented data)     and cause a denial of service in uip_reass() in uip.c,     or possibly execute arbitrary code on some target     architectures.(CVE-2020-17438)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
