Ubuntu 23.10 USN-6450-1 Critical: OpenSSL Access Issues

Several security issues were fixed in OpenSSL.. ========================================================================== Ubuntu Security Notice USN-6450-1 October 24, 2023 openssl vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 23.10 - Ubuntu 23.04 - Ubuntu 22.04 LTS Summary: Several security issues were fixed in OpenSSL. Software Description: - openssl: Secure Socket Layer (SSL) cryptographic library and tools Details: Tony Battersby discovered that OpenSSL incorrectly handled key and initialization vector (IV) lengths. This could lead to truncation issues and result in loss of confidentiality for some symmetric cipher modes. (CVE-2023-5363) Juerg Wullschleger discovered that OpenSSL incorrectly handled the AES-SIV cipher. This could lead to empty data entries being ignored, resulting in certain applications being misled. This issue only affected Ubuntu 22.04 LTS and Ubuntu 23.04. (CVE-2023-2975) It was discovered that OpenSSL incorrectly handled checking excessively long DH keys or parameters. A remote attacker could possibly use this issue to cause OpenSSL to consume resources, leading to a denial of service. This issue only affected Ubuntu 22.04 LTS and Ubuntu 23.04. (CVE-2023-3446, CVE-2023-3817) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 23.10: libssl3 3.0.10-1ubuntu2.1 Ubuntu 23.04: libssl3 3.0.8-1ubuntu1.4 Ubuntu 22.04 LTS: libssl3 3.0.2-0ubuntu1.12 After a standard system update you need to reboot your computer to make all the necessary changes.
