Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (4.30%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

A heap-buffer overflow was found in the way samba clients processed extra long filename in a directory listing. A malicious samba server could use this flaw to cause arbitrary code execution on a samba client. Samba versions before 4.6.16, 4.7.9 and 4.8.4 are vulnerable.
