CVE ID         : CVE-2018-10858 CVE-2018-10919

Several vulnerabilities have been discovered in Samba, a SMB/CIFS file,
print, and login server for Unix. The Common Vulnerabilities and
Exposures project identifies the following issues:

CVE-2018-10858

    Svyatoslav Phirsov discovered that insufficient input validation in
    libsmbclient allowed a malicious Samba server to write to the
    client's heap memory.

CVE-2018-10919

    Phillip Kuhrt discovered that Samba when acting as an Active Domain
    controller disclosed some sensitive attributes.

For Debian 8 "Jessie", these problems have been fixed in version
4.2.14+dfsg-0+deb8u10.

We recommend that you upgrade your samba packages.
