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.

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6259-1 advisory.

  - 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)

  - 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 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)

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

The remote SUSE Linux SLES12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:2806-1 advisory.
