Several vulnerabilities have been discovered in Samba, a SMB/CIFS file, print, and login server for Unix, which might result in bypass of access checks, overwrite of files in unintended situations using the WORM vfs module, installing CA certificates over http without verification when auto-enrollment GPO is enabled, denial of service or remote code execution.



For Debian 10 buster, these problems have been fixed in version 2:4.9.5+dfsg-5+deb10u7.

We recommend that you upgrade your samba packages.
