Vulnerability from variot

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. Multiple open-source embedded TCP/IP stacks, commonly used in Internet of Things (IoT) and embedded devices, have several vulnerabilities stemming from improper memory management. These vulnerabilities are also tracked as ICS-VU-633937 and JVNVU#96491057 as well as the name AMNESIA:33.CVE-2020-13984 Not Affected CVE-2020-13985 Affected CVE-2020-13986 Affected CVE-2020-13987 Affected CVE-2020-13988 Affected CVE-2020-17437 Affected CVE-2020-17438 Affected CVE-2020-17439 Affected CVE-2020-17440 Affected CVE-2020-17441 Not Affected CVE-2020-17442 Not Affected CVE-2020-17443 Not Affected CVE-2020-17444 Not Affected CVE-2020-17445 Not Affected CVE-2020-17467 Not Affected CVE-2020-17468 Not Affected CVE-2020-17469 Not Affected CVE-2020-17470 Not Affected CVE-2020-24334 Affected CVE-2020-24335 Not Affected CVE-2020-24336 Affected CVE-2020-24337 Not Affected CVE-2020-24338 Not Affected CVE-2020-24339 Not Affected CVE-2020-24340 Not Affected CVE-2020-24341 Not Affected CVE-2020-24383 Not Affected CVE-2020-25107 Not Affected CVE-2020-25108 Not Affected CVE-2020-25109 Not Affected CVE-2020-25110 Not Affected CVE-2020-25111 Not Affected CVE-2020-25112 Not Affected CVE-2021-28362 Not AffectedCVE-2020-13984 Not Affected CVE-2020-13985 Affected CVE-2020-13986 Affected CVE-2020-13987 Affected CVE-2020-13988 Affected CVE-2020-17437 Affected CVE-2020-17438 Affected CVE-2020-17439 Affected CVE-2020-17440 Affected CVE-2020-17441 Not Affected CVE-2020-17442 Not Affected CVE-2020-17443 Not Affected CVE-2020-17444 Not Affected CVE-2020-17445 Not Affected CVE-2020-17467 Not Affected CVE-2020-17468 Not Affected CVE-2020-17469 Not Affected CVE-2020-17470 Not Affected CVE-2020-24334 Affected CVE-2020-24335 Not Affected CVE-2020-24336 Affected CVE-2020-24337 Not Affected CVE-2020-24338 Not Affected CVE-2020-24339 Not Affected CVE-2020-24340 Not Affected CVE-2020-24341 Not Affected CVE-2020-24383 Not Affected CVE-2020-25107 Not Affected CVE-2020-25108 Not Affected CVE-2020-25109 Not Affected CVE-2020-25110 Not Affected CVE-2020-25111 Not Affected CVE-2020-25112 Not Affected CVE-2021-28362 Not Affected. Contiki is an open source cross-platform operating system for IoT (Internet of Things) devices. Contiki-OS has a buffer error vulnerability that stems from not checking the length field of the packet header based on the available data in the packet. Given any length, an out-of-bounds memory read can be performed during the checksum calculation. ========================================================================= Ubuntu Security Notice USN-6259-1 July 27, 2023

open-iscsi vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 20.04 LTS
  • Ubuntu 18.04 LTS (Available with Ubuntu Pro)
  • Ubuntu 16.04 LTS (Available with Ubuntu Pro)

Summary:

Several security issues were fixed in Open-iSCSI.

Software Description: - open-iscsi: Open Source iSCSI implementation

Details:

Jos Wetzels, Stanislav Dashevskyi, and Amine Amri discovered that Open-iSCSI incorrectly handled certain checksums for IP packets. An attacker could possibly use this issue to expose sensitive information. (CVE-2020-13987)

Jos Wetzels, Stanislav Dashevskyi, Amine Amri discovered that Open-iSCSI incorrectly handled certain parsing TCP MSS options. An attacker could possibly use this issue to cause a crash or cause unexpected behavior. (CVE-2020-13988)

Amine Amri and Stanislav Dashevskyi discovered that Open-iSCSI incorrectly handled certain TCP data. An attacker could possibly use this issue to expose sensitive information. (CVE-2020-17437)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 20.04 LTS: open-iscsi 2.0.874-7.1ubuntu6.4

Ubuntu 18.04 LTS (Available with Ubuntu Pro): open-iscsi 2.0.874-5ubuntu2.11+esm1

Ubuntu 16.04 LTS (Available with Ubuntu Pro): open-iscsi 2.0.873+git0.3b4b4500-14ubuntu3.7+esm1

In general, a standard system update will make all the necessary changes.
