An update of the systemd package has been released.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - systemd-tmpfiles in systemd before 237 attempts to support ownership/permission changes on hardlinked     files even if the fs.protected_hardlinks sysctl is turned off, which allows local users to bypass intended     access restrictions via vectors involving a hard link to a file for which the user lacks write access, as     demonstrated by changing the ownership of the /etc/passwd file. (CVE-2017-18078)

Note that Nessus relies on the presence of the package as reported by the vendor.

This update for systemd fixes the following issues :

Security issue fixed :

  - CVE-2017-18078: tmpfiles: refuse to chown()/chmod()     files which are hardlinked, unless protected_hardlinks     sysctl is on. This could be used by local attackers to     gain privileges (bsc#1077925)

Non Security issues fixed :

  - core: use id unit when retrieving unit file state     (#8038) (bsc#1075801)

  - cryptsetup-generator: run cryptsetup service before swap     unit (#5480)

  - udev-rules: all values can contain escaped double quotes     now (#6890)

  - strv: fix buffer size calculation in strv_join_quoted()

  - tmpfiles: change ownership of symlinks too

  - stdio-bridge: Correctly propagate error

  - stdio-bridge: remove dead code

  - remove bus-proxyd (bsc#1057974)

  - core/timer: Prevent timer looping when unit cannot start     (bsc#1068588)

  - Make systemd-timesyncd use the openSUSE NTP servers by     default Previously systemd-timesyncd used the Google     Public NTP servers time(1..4).google.com

  - Don't ship /usr/lib/systemd/system/tmp.mnt at all     (bsc#1071224) But we still ship a copy in /var. Users     who want to use tmpfs on /tmp are supposed to add a     symlink in /etc/ pointing to the copy shipped in /var.
    To support the update path we automatically create the     symlink if tmp.mount in use is located in /usr.

  - Enable systemd-networkd on Leap distros only     (bsc#1071311)

This update was imported from the SUSE:SLE-12-SP2:Update update project.

An update of 'systemd' packages of Photon OS has been released.

According to the versions of the systemd packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - systemd: Out-of-bounds heap write in systemd-networkd     dhcpv6 option handling (CVE-2018-15688)

  - systemd: stack overflow when calling syslog from a     command with long cmdline (CVE-2018-16864)

  - systemd: stack overflow when receiving many journald     entries (CVE-2018-16865)

  - systemd: Assertion failure when PID 1 receives a     zero-length message over notify socket(CVE-2016-7795)

  - systemd: Unsafe handling of hard links allowing     privilege escalation(CVE-2017-18078)

  - systemd: Out-of-bounds write in systemd-resolved due to     allocating too small buffer in     dns_packet_new(CVE-2017-9445)

  - systemd: memory leak in journald-server.c introduced by     fix for CVE-2018-16864 (CVE-2019-3815)

According to the versions of the systemd packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - A flaw was found in the way systemd handled empty     notification messages. A local attacker could use this     flaw to make systemd freeze its execution, preventing     further management of system services, system shutdown,     or zombie process collection via     systemd.i1/4^CVE-2016-7795i1/4%0

  - systemd-tmpfiles in systemd before 237 attempts to     support ownership/permission changes on hardlinked     files even if the fs.protected_hardlinks sysctl is     turned off, which allows local users to bypass intended     access restrictions via vectors involving a hard link     to a file for which the user lacks write access, as     demonstrated by changing the ownership of the     /etc/passwd file.i1/4^CVE-2017-18078i1/4%0
