Amazon Linux 2 Security Advisory: ALAS-2020-1459
Advisory Release Date: 2020-07-14 02:45 Pacific
Advisory Updated Date: 2020-07-17 00:43 Pacific
A flaw was found in the samba client, all samba versions before samba 4.11.2, 4.10.10 and 4.9.15, where a malicious server can supply a pathname to the client with separators. This could allow the client to access files and folders outside of the SMB network pathnames. An attacker could use this vulnerability to create files outside of the current working directory using the privileges of the client user. (CVE-2019-10218)
A flaw was found in samba versions 4.9.x up to 4.9.13, samba 4.10.x up to 4.10.8 and samba 4.11.x up to 4.11.0rc3, when certain parameters were set in the samba configuration file. An unauthenticated attacker could use this flaw to escape the shared directory and access the contents of directories outside the share. (CVE-2019-10197)
