Red Hat Security Advisory: tpm2-tools security update
Two security vulnerabilities were identified in the tpm2-tools package used for managing TPM 2.0 devices on Red Hat Enterprise Linux 9. The first vulnerability (CVE-2024-29038) allows arbitrary quote data to go undetected by the tpm2_checkquote utility. The second vulnerability (CVE-2024-29039) involves the PCR selection value not being compared with the attest, potentially undermining the integrity checks. Red Hat has issued a security update addressing these issues with a low severity rating. The update is available for multiple Red Hat Enterprise Linux 9 variants and architectures.
AI Analysis
Technical Summary
The tpm2-tools package for Red Hat Enterprise Linux 9 contained two vulnerabilities: CVE-2024-29038 where arbitrary quote data could bypass detection by the tpm2_checkquote tool, and CVE-2024-29039 where the PCR selection value was not properly compared with the attest data. These issues could affect the reliability of TPM quote verification. Red Hat released an update (RHSA-2024:9424) that fixes these vulnerabilities by correcting the quote validation logic. The advisory rates the impact as low and provides updated packages for various RHEL 9 versions and architectures.
Potential Impact
The vulnerabilities may allow invalid or manipulated TPM quote data to be accepted as valid, potentially weakening the trustworthiness of TPM-based attestation processes. However, Red Hat rates the security impact as low, indicating limited risk or exploitability in typical environments. There are no known exploits in the wild at this time.
Mitigation Recommendations
Red Hat has released an official security update (RHSA-2024:9424) for tpm2-tools on Red Hat Enterprise Linux 9 that addresses these vulnerabilities. Users should apply the update promptly following Red Hat's guidance at https://access.redhat.com/articles/11258. No additional mitigation actions are indicated by the vendor advisory.
