EulerOS Virtualization 2.9.0 : open-iscsi (EulerOS-SA-2021-1639)
high Nessus Plugin ID 147664
Synopsis
The remote EulerOS Virtualization host is missing multiple security updates.Description
According to the versions of the open-iscsi package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :- An issue was discovered in uIP 1.0, as used in Contiki 3.0 and other products. When the Urgent flag is set in a TCP packet, and the stack is configured to ignore the urgent data, the stack attempts to use the value of the Urgent pointer bytes to separate the Urgent data from the normal data, by calculating the offset at which the normal data should be present in the global buffer.
However, the length of this offset is not checked therefore, for large values of the Urgent pointer bytes, the data pointer can point to memory that is way beyond the data buffer in uip_process in uip.c.(CVE-2020-17437)
- An issue was discovered in Contiki through 3.0. An Integer Overflow exists in the uIP TCP/IP Stack component when parsing TCP MSS options of IPv4 network packets in uip_process in net/ipv4/uip.c.(CVE-2020-13988)
- An issue was discovered in Contiki through 3.0. An Out-of-Bounds Read vulnerability exists in the uIP TCP/IP Stack component when calculating the checksums for IP packets in upper_layer_chksum in net/ipv4/uip.c.(CVE-2020-13987)
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.
