CBL Mariner 2.0 Security Update: cloud-hypervisor (CVE-2023-28448)

high Nessus Plugin ID 174564

Synopsis

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

Description

The version of cloud-hypervisor 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-2023-28448 advisory.

 - Versionize is a framework for version tolerant serializion/deserialization of Rust data structures, designed for usecases that need fast deserialization times and minimal size overhead. An issue was discovered in the Versionize::deserialize' implementation provided by the versionize' crate for vmm_sys_utils::fam::FamStructWrapper', which can lead to out of bounds memory accesses. The impact started with version 0.1.1. The issue was corrected in version 0.1.10 by inserting a check that verifies, for any deserialized header, the lengths of compared flexible arrays are equal and aborting deserialization otherwise. (CVE-2023-28448)

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

Solution

Update the affected packages.
