========================================================================== Ubuntu Security Notice USN-7278-1 February 20, 2025
openssl vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 24.04 LTS - Ubuntu 22.04 LTS - Ubuntu 20.04 LTS Summary: Several security issues were fixed in OpenSSL. Software Description: - openssl: Secure Socket Layer (SSL) cryptographic library and tools Details: George Pantelakis and Alicja Kario discovered that OpenSSL had a timing side-channel when performing ECDSA signature computations. A remote attacker could possibly use this issue to recover private data. (CVE-2024-13176) It was discovered that OpenSSL incorrectly handled certain memory operations when using low-level GF(2^m) elliptic curve APIs with untrusted explicit values for the field polynomial. When being used in this uncommon fashion, a remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2024-9143) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 24.04 LTS libssl3t64 3.0.13-0ubuntu3.5 openssl 3.0.13-0ubuntu3.5 Ubuntu 22.04 LTS libssl3 3.0.2-0ubuntu1.19 openssl 3.0.2-0ubuntu1.19 Ubuntu 20.04 LTS libssl1.1 1.1.1f-1ubuntu2.24 openssl 1.1.1f-1ubuntu2.24 After a standard system update you need to reboot your computer to make all the necessary changes.
