SSA-539476SSA-539476: Siemens SIMATIC NET CP, SINEMA and SCALANCE Products Affected by Vulnerabilities in Third-Party Component strongSwan2022-02-08csaf · siemens_psirtDE
Vulnerabilities in the third-party component strongSwan could allow an attacker to cause a denial of service (DoS) condition in affected devices by exploiting integer overflow bugs. Siemens has released updates for the affected products and recommends to update to the latest versions.
VDE-2022-010PHOENIX CONTACT: Multiple Linux component vulnerabilities fixed in latest AXC F x152 LTS release2022-04-12csaf · phoenix_contact_psirtDE
PLCnext Control AXC F x152 is certified according to IEC 62443-4-1 and IEC 62443-4-2. This certification requires that all third-party components used in the firmware are regularly checked for known vulnerabilities. Firmware components in version 2021.06 had already been updated. For the 2022.0 LTS version more firmware components have been updated implicitly fixing the vulnerabilities listed. The vulnerabilities listed above have not been individually verified in terms of actual impact and/or limitations in combination with the affected products listed. The current LTS release 2022.0 LTS contains updates of integrated third-party libraries, SDKs and other third-party software to address these issues nevertheless. UPDATE A (April 4th, 2022): Added RFC 4072 (Art. No. 1051328) and fixed affected version of AXC F 3152
