An update that solves three vulnerabilities and has one errata is now available. . SUSE Security Update: Security update for systemd ______________________________________________________________________________ Announcement ID: SUSE-SU-2019:0053-1 Rating: important References: #1068588 #1071558 #1113665 #1120323 Cross-References: CVE-2018-15686 CVE-2018-16864 CVE-2018-16865 Affected Products: SUSE Linux Enterprise Server 12-LTSS ______________________________________________________________________________ An update that solves three vulnerabilities and has one errata is now available. Description: 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).
