CBL Mariner 2.0 Security Update: virglrenderer (CVE-2022-0175)

medium Nessus Plugin ID 173510

Synopsis

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

Description

The version of virglrenderer 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-2022-0175 advisory.

 - A flaw was found in the VirGL virtual OpenGL renderer (virglrenderer). The virgl did not properly initialize memory when allocating a host-backed memory resource. A malicious guest could use this flaw to mmap from the guest kernel and read this uninitialized memory from the host, possibly leading to information disclosure. (CVE-2022-0175)

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.
