Amazon Linux 2 Security Advisory: ALAS-2020-1544
Advisory Release Date: 2020-10-22 18:38 Pacific
Advisory Updated Date: 2020-10-22 22:33 Pacific
Severity:
Medium
Issue Overview:
All samba versions 4.9.x before 4.9.18, 4.10.x before 4.10.12 and 4.11.x before 4.11.5 have an issue where if it is set with "log level = 3" (or above) then the string obtained from the client, after a failed character conversion, is printed. Such strings can be provided during the NTLMSSP authentication exchange. In the Samba AD DC in particular, this may cause a long-lived process(such as the RPC server) to terminate. (In the file server case, the most likely target, smbd, operates as process-per-client and so a crash there is harmless). (CVE-2019-14907)
Affected Packages:
samba
