Package : samba
Version : 2:4.2.14+dfsg-0+deb8u13
CVE ID : CVE-2018-16860

Isaac Boukris and Andrew Bartlett discovered that the S4U2Self Kerberos
extension used in Samba's Active Directory support was susceptible to
man-in-the-middle attacks caused by incomplete checksum validation.

For Debian 8 "Jessie", this problem has been fixed in version
2:4.2.14+dfsg-0+deb8u13.

We recommend that you upgrade your samba packages.
