The Qualys Research Labs discovered multiple vulnerabilities in systemd-journald. Two memory corruption flaws, via attacker-controlled allocations using the alloca function (CVE-2018-16864, CVE-2018-16865 ) and an out-of-bounds read flaw leading to an information leak (CVE-2018-16866 ), could allow an attacker to cause a denial of service or the execution of arbitrary code.
