CVE-2020-25721
Kerberos acceptors need easy access to stable AD identifiers (eg objectSid).
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.20%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Kerberos acceptors need easy access to stable AD identifiers (eg objectSid). Samba as an AD DC now provides a way for Linux applications to obtain a reliable SID (and samAccountName) in issued tickets.
