Red Hat Security Advisory 2024-0500-03 - An update for openssl is now available for Red Hat Enterprise Linux 9.2 Extended Update Support.
An issue exists in SoftIron HyperCloud where compute nodes may come online immediately without following the correct initialization process. In this instance, workloads may be scheduled on these nodes and deploy to a failed or erroneous state, which impacts the availability of these workloads that may be deployed during this time window. This issue impacts HyperCloud versions from 2.0.0 to before 2.0.3.
Issue summary: A bug has been identified in the processing of key and initialisation vector (IV) lengths. This can lead to potential truncation or overruns during the initialisation of some symmetric ciphers. Impact summary: A truncation in the IV can result in non-uniqueness, which could result in loss of confidentiality for some cipher modes. When calling EVP_EncryptInit_ex2(), EVP_DecryptInit_ex2() or EVP_CipherInit_ex2() the provided OSSL_PARAM array is processed after the key and IV have been established. Any alterations to the key length, via the "keylen" parameter or the IV length, via the "ivlen" parameter, within the OSSL_PARAM array will not take effect as intended, potentially causing truncation or overreading of these values. The following ciphers and cipher modes are impacted: RC2, RC4, RC5, CCM, GCM and OCB. For the CCM, GCM and OCB cipher modes, truncation of the IV can result in loss of confidentiality. For example, when following NIST's SP 800-38D section 8.2.1 ...
Debian Linux Security Advisory 5532-1 - Tony Battersby reported that incorrect cipher key and IV length processing in OpenSSL, a Secure Sockets Layer toolkit, may result in loss of confidentiality for some symmetric cipher modes.
Ubuntu Security Notice 6450-1 - Tony Battersby discovered that OpenSSL incorrectly handled key and initialization vector lengths. This could lead to truncation issues and result in loss of confidentiality for some symmetric cipher modes. 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.
