The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3766 advisory.
An issue was discovered in OpenZFS through 2.0.3. When an NFS share is exported to IPv6 addresses via the sharenfs feature, there is a silent failure to parse the IPv6 address data, and access is allowed to everyone. IPv6 restrictions from the configuration are not applied. (CVE-2013-20001)
OpenZFS through 2.1.13 and 2.2.x through 2.2.1, in certain scenarios involving applications that try to rely on efficient copying of file data, can replace file contents with zero-valued bytes and thus potentially disable security mechanisms. NOTE: this issue is not always security related, but can be security related in realistic situations. A possible example is cp, from a recent GNU Core Utilities (coreutils) version, when attempting to preserve a rule set for denying unauthorized access. (One might use cp when configuring access control, such as with the /etc/hosts.deny file specified in the IBM Support reference.) NOTE: this issue occurs less often in version 2.2.1, and in versions before 2.1.4, because of the default configuration in those versions. (CVE-2023-49298)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
