ReadyNAS 524X vulnerability?

I get Nessus reports of one detected vulnerability in a ReadyNAS 524X with firmware 6.10.7.

 

Vulnerability Desc:The version of Samba running on the remote host is 4.13.x prior to 4.13.17, 4.14.x prior to 4.14.12, or 4.15.x prior to 4.15.5. It is, therefore, affected by multiple vulnerabilities: - Out-of-bounds heap read/write vulnerability in VFS module vfs_fruit allows code execution. (CVE-2021-44142) - Information leak via symlinks of existence of files or directories outside of the exported share. (CVE-2021-44141) - Samba AD users with permission to write to an account can impersonate arbitrary services. (CVE-2022-0336) Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Vendor Fix:Upgrade to Samba version 4.13.17, 4.14.12, or 4.15.5 or later.

 

Anyone know if/when this will be fixed?

  • FYI, I see a very old version on 6.10.7

    root@NAS:~# smbstatus --version
    Version 4.8.0

     

    But Netgear might be backporting security fixes.  Tagging the mods, so they can follow up:  Mark_V and JeraldM
