  • 1.  Samba 4.12.10-1 msdfs link read errors re-introduced ?

    Posted Tue February 09, 2021 01:13 AM
    Samba 4.12.10-1 cannot display/read msdfs links - generating 'math routine'  errors reading msdfs links. 

    Appears to be same error that was fixed 10/25/2018  in 4.6.16  "uploaded Samba-4.6.16 which addresses the latest CVEs and the msdfs links issue"

    ref thread from Sept 2018

    Thanks for reporting the issue. 
    There were lot of code changes in the new releases. So that could have introduced this. 
    Working on a fix. Probably this week or next week a fixed samba will be available in Toolbox.

    We are unable to upload the rpms to Toolbox because the upload infra is down because of US winter storm. 
    Hopefully will be able to upload next week.
