Free For Apple Install Google Chrome 117.0.5938.132: Potential Security Issues with Cipher Modes

Google Chrome version 117.0.5938.132, now available for free download on Apple devices, comes with a crucial security update that addresses potential vulnerabilities in the cipher modes used by some symmetric encryption algorithms. According to official documentation, the following ciphers and cipher modes are impacted: RC2, RC4, RC5, CCM, GCM, and OCB.

One of the main issues identified is truncation of the Initialization Vector (IV), which can occur when using the CCM, GCM, or OCB cipher modes. This truncation can result in a loss of uniqueness for the IV values, potentially leading to security breaches. Furthermore, when calling EVP_EncryptInit_ex2(), EVP_DecryptInit_ex2(), or EVP_CipherInit_ex2() functions, the provided OSSL_PARAM array may not be processed as intended, causing overreading or truncation of these values.

The bug identified in the processing of key and initialization parameters could result in loss of confidentiality for some cipher modes. To mitigate this issue, developers should ensure that they provide the correct IV length via the 'ivlen' parameter when calling these functions.

In summary, the security update addresses potential vulnerabilities in symmetric encryption algorithms used by Google Chrome version 117.0.5938.132 on Apple devices. The affected cipher modes include RC2, RC4, RC5, CCM, GCM, and OCB. To ensure optimal security, developers should be aware of the potential issues associated with IV truncation and overreading, and take necessary measures to prevent confidentiality breaches.
