CBL Mariner 2.0 Security Update: cloud-hypervisor-cvm / edk2 / openssl (CVE-2024-6119)

high Nessus Plugin ID 207819

Synopsis

The remote CBL Mariner host is missing one or more security updates.

Description

The version of cloud-hypervisor-cvm / edk2 / openssl installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-6119 advisory.

 - Issue summary: Applications performing certificate name checks (e.g., TLS clients checking server certificates) May attempt to read an invalid memory address resulting in abnormal termination of the application process. Impact summary: Abnormal termination of an application can a cause a denial of service. Applications performing certificate name checks (e.g., TLS clients checking server certificates) May attempt to read an invalid memory address when comparing the expected name with an `otherName` subject alternative name of an X.509 certificate. This May result in an exception that terminates the application program. Note that basic certificate chain validation (signatures, dates, ...) is not affected, the denial of service can occur only when the application also specifies an expected DNS name, Email address or IP address. TLS servers rarely solicit client certificates, and even when they do, they generally don't perform a name check against a reference identifier (expected identity), but rather extract the presented identity after checking the certificate chain. So TLS servers are generally not affected and the severity of the issue is Moderate. The FIPS modules in 3.3, 3.2, 3.1 and 3.0 are not affected by this issue.
 (CVE-2024-6119)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
