Vulnerability from variot - Updated: 2023-12-18 11:41An 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. 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. Siemens SENTRON PAC3200, etc. are all products of German Siemens (Siemens). Siemens SENTRON PAC3200 is a multifunctional power meter for industrial environments. Siemens SENTRON PAC4200 is a multifunctional power meter for industrial environments. Siemens SIRIUS 3RW5 is a soft start device for industrial environments.
The Siemens device has an input verification error vulnerability. Attackers can use this vulnerability to send a specially crafted IP packet to a device located on the same network to trigger a denial of service condition on the device. ========================================================================= 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.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
Browse all ATT&CK techniques and the vulnerabilities related to each.
