CBL Mariner 2.0 Security Update: hyperv-daemons (CVE-2023-42753)

high Nessus Plugin ID 183060

Synopsis

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

Description

The version of hyperv-daemons 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-2023-42753 advisory.

 - An array indexing vulnerability was found in the netfilter subsystem of the Linux kernel. A missing macro could lead to a miscalculation of the `h->nets` array offset, providing attackers with the primitive to arbitrarily increment/decrement a memory buffer out-of-bound. This issue may allow a local user to crash the system or potentially escalate their privileges on the system. (CVE-2023-42753)

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.
