SynopsisThe remote Debian host is missing a security update.
DescriptionIsaac 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.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
