CBL Mariner 2.0 Security Update: libpcap / nmap (CVE-2024-8006)

medium Nessus Plugin ID 210130

Synopsis

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

Description

The version of libpcap / nmap 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-2024-8006 advisory.

 - Remote packet capture support is disabled by default in libpcap. When a user builds libpcap with remote packet capture support enabled, one of the functions that become available is pcap_findalldevs_ex(). One of the function arguments can be a filesystem path, which normally means a directory with input data files. When the specified path cannot be used as a directory, the function receives NULL from opendir(), but does not check the return value and passes the NULL value to readdir(), which causes a NULL pointer derefence. (CVE-2024-8006)

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.
