Detail
| A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 18.10 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS Summary: Several security issues were fixed in systemd. Software Description: - systemd: system and service manager Details: It was discovered that systemd-journald allocated variable-length buffers for certain message fields on the stack. A local attacker could potentially exploit this to cause a denial of service, or execute arbitrary code. (CVE-2018-16864) It was discovered that systemd-journald allocated variable-length arrays of objects representing message fields on the stack. A local attacker could potentially exploit this to cause a denial of service, or execute arbitrary code. (CVE-2018-16865) An out-of-bounds read was discovered in systemd-journald. A local attacker could potentially exploit this to obtain sensitive information and bypass ASLR protections. (CVE-2018-16866) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 18.10: ﾃつ systemdﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ 239-7ubuntu10.6 Ubuntu 18.04 LTS: ﾃつ systemdﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ 237-3ubuntu10.11 Ubuntu 16.04 LTS: ﾃつ systemdﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ 229-4ubuntu21.15 After a standard system update you need to reboot your computer to make all the necessary changes.
