Security update for systemd
This update for systemd provides the following fixes:
Security issues fixed:
- CVE-2018-16864, CVE-2018-16865: Fixed two memory corruptions through attacker-controlled alloca()s (bsc#1120323)
- CVE-2018-16866: Fixed an information leak in journald (bsc#1120323)
- Fixed an issue during system startup in relation to encrypted swap disks (bsc#1119971)
Non-security issues fixed:
- core: Queue loading transient units after setting their properties. (bsc#1115518)
- logind: Stop managing VT switches if no sessions are registered on that VT. (bsc#1101591)
- terminal-util: introduce vt_release() and vt_restore() helpers.
- terminal: Unify code for resetting kbd utf8 mode a bit.
- terminal Reset should honour default_utf8 kernel setting.
- logind: Make session_restore_vt() static.
- udev: Downgrade message when settting inotify watch up fails. (bsc#1005023)
- log: Never log into foreign fd #2 in PID 1 or its pre-execve() children. (bsc#1114981)
- udev: Ignore the exit code of systemd-detect-virt for memory hot-add. In SLE-12-SP3, 80-hotplug-cpu-mem.rules has a memory hot-add rule that uses systemd-detect-virt to detect non-zvm environment. The systemd-detect-virt returns exit failure code when it detected none state. The exit failure code causes that the hot-add memory block can not be set to online. (bsc#1076696)

Описание
An allocation of memory without limits, that could result in the stack clashing with another memory region, was discovered in systemd-journald when a program with long command line arguments calls syslog. A local attacker may use this flaw to crash systemd-journald or escalate his privileges. Versions through v240 are vulnerable.

Описание
An allocation of memory without limits, that could result in the stack clashing with another memory region, was discovered in systemd-journald when many entries are sent to the journal socket. A local attacker, or a remote one if systemd-journal-remote is used, may use this flaw to crash systemd-journald or execute code with journald privileges. Versions through v240 are vulnerable.
