------------------------------------------------------------------------- Debian LTS Advisory DLA-4114-1 [email protected] https://www.debian.org/lts/security/ Daniel Leidert April 05, 2025 https://wiki.debian.org/LTS
-------------------------------------------------------------------------

Package : zfs-linux Version : 2.0.3-9+deb11u2 CVE ID : CVE-2013-20001 CVE-2023-49298 Debian Bug : 1056752 1059322

Multiple vulnerabilities were found in zfs-linux, the OpenZFS filesystem for Linux.

CVE-2013-20001

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. With the fix, recognize when the host part of a sharenfs attribute is an ipv6 Literal, and pass that through without modification.

CVE-2023-49298

Check dnode and its data for dirtiness to prevent applications from inadvertently replacing file contents with zero-valued bytes and thus potentially disabling security mechanisms.

For Debian 11 bullseye, these problems have been fixed in version 2.0.3-9+deb11u2.

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:
