SystemD and Putty Updates for Debian 8 LTS
Posted on: 04/25/2019 07:36 AM

The following updates has been released for Debian GNU/Linux 8 LTS:

DLA 1762-1: systemd security update
DLA 1763-1: putty security update

DLA 1762-1: systemd security update
Package : systemd
Version : 215-17+deb8u12
CVE ID : CVE-2017-18078 CVE-2019-3842


Two vulnerabilities have been addressed in the systemd components
systemd-tmpfiles and pam_systemd.so.

CVE-2017-18078

systemd-tmpfiles in systemd attempted to support ownership/permission
changes on hardlinked files even if the fs.protected_hardlinks sysctl
is turned off, which allowed local users to bypass intended access
restrictions via vectors involving a hard link to a file for which
the user lacked write access.

CVE-2019-3842

It was discovered that pam_systemd did not properly sanitize the
environment before using the XDG_SEAT variable. It was possible for
an attacker, in some particular configurations, to set a XDG_SEAT
environment variable which allowed for commands to be checked against
polkit policies using the "allow_active" element rather than
"allow_any".

For Debian 8 "Jessie", these problems have been fixed in version
215-17+deb8u12.

We recommend that you upgrade your systemd packages.
