Package : samba
CVE ID : CVE-2019-10197

Stefan Metzmacher discovered a flaw in Samba, a SMB/CIFS file, print,
and login server for Unix. Specific combinations of parameters and
permissions can allow user to escape from the share path definition and
see the complete '/' filesystem. Unix permission checks in the kernel
are still enforced.

Details can be found in the upstream advisory at
https://www.samba.org/samba/security/CVE-2019-10197.html

For the stable distribution (buster), this problem has been fixed in
version 2:4.9.5+dfsg-5+deb10u1.

We recommend that you upgrade your samba packages.

tracker page at:
