 Package : zfs-linux Version : 0.7.12-2+deb10u3 CVE ID : CVE-2013-20001 CVE-2023-49298 Debian Bug : 1059322 1056752

 A couple of vulnerabilities were found in zfs-linux.

 CVE-2013-20001

 In OpenZFS, 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-2023-49298

 OpenZFS 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.

 For Debian 10 buster, these problems have been fixed in version 0.7.12-2+deb10u3.

 We recommend that you upgrade your zfs-linux packages.

 For the detailed security status of zfs-linux please refer to its security tracker page at:

Tenable has extracted the preceding description block directly from the Debian security advisory.

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

Solution

Upgrade the libnvpair1linux packages.
