EulerOS Virtualization 2.9.1 : open-iscsi (EulerOS-SA-2021-1718)

critical Nessus Plugin ID 148620

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

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.

Solution

Update the affected open-iscsi package.
