Security update for systemd SUSE Patch security@suse.de SUSE Security Team SUSE-SU-2019:0053-1 Final 1 1 2019-01-09T21:07:59Z current 2019-01-09T21:07:59Z 2019-01-09T21:07:59Z cve-database/bin/generate-cvrf.pl 2017-02-24T01:00:00Z Security update for systemd This update for systemd fixes the following issues: * Fix security vulnerabilities CVE-2018-16864 and CVE-2018-16865 (bsc#1120323): Both issues were memory corruptions via attacker-controlled alloca which could have been used to gain root privileges by a local attacker. * Fix security vulnerability CVE-2018-15686 (bsc#1113665): A vulnerability in unit_deserialize of systemd used to allow an attacker to supply arbitrary state across systemd re-execution via NotifyAccess. This could have been used to improperly influence systemd execution and possibly lead to root privilege escalation. * Remedy 2048 character line-length limit in systemd-sysctl code that would cause parser failures if /etc/sysctl.conf contained lines that exceeded this length (bsc#1071558). * Fix a bug in systemd's core timer code that would cause timer looping under certain conditions, resulting in hundreds of syslog messages being written to the journal (bsc#1068588).
