AI Analysis
Technical Summary
The opencryptoki packages, which implement version 2.11 of the PKCS#11 API for IBM Cryptocards and software tokens, contain a timing side-channel vulnerability in the handling of RSA PKCS#1 v1.5 padded ciphertexts (CVE-2024-0914). This vulnerability allows attackers to potentially extract sensitive information by measuring the time taken during cryptographic operations. Red Hat has issued a security advisory (RHSA-2024:1992) providing an update that fixes this issue for Red Hat Enterprise Linux 8.6 Extended Update Support. The advisory rates the impact as moderate and provides updated packages to remediate the vulnerability.
Potential Impact
The vulnerability allows an attacker to exploit timing side-channel information leakage during RSA PKCS#1 v1.5 ciphertext processing, potentially compromising cryptographic keys or sensitive data. The impact is rated moderate by Red Hat. There are no known exploits in the wild at this time.
Mitigation Recommendations
Red Hat has released an official security update that fixes this timing side-channel vulnerability in opencryptoki. Users of affected Red Hat Enterprise Linux 8.6 Extended Update Support versions should apply the update as described in Red Hat advisory RHSA-2024:1992 and the referenced article https://access.redhat.com/articles/11258. No additional mitigation steps are required beyond applying the official patch.
