========================================================================== Ubuntu Security Notice USN-5710-1 November 01, 2022 openssl vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 22.10 - Ubuntu 22.04 LTS Summary: Several security issues were fixed in OpenSSL. Software Description: - openssl: Secure Socket Layer (SSL) cryptographic library and tools Details: It was discovered that OpenSSL incorrectly handled certain X.509 Email Addresses. If a certificate authority were tricked into signing a specially-crafted certificate, a remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. The default compiler options for affected releases reduce the vulnerability to a denial of service. (CVE-2022-3602, CVE-2022-3786) It was discovered that OpenSSL incorrectly handled applications creating custom ciphers via the legacy EVP_CIPHER_meth_new() function. This issue could cause certain applications that mishandled values to the function to possibly end up with a NULL cipher and messages in plaintext. (CVE-2022-3358) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 22.10: libssl3 3.0.5-2ubuntu2 Ubuntu 22.04 LTS: libssl3 3.0.2-0ubuntu1.7 After a standard system update you need to reboot your computer to make all the necessary changes.
