Red Hat Security Advisory 2020-1264-01 - The systemd packages contain systemd, a system and service manager for Linux, compatible with the SysV and LSB init scripts. It provides aggressive parallelism capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, and keeps track of processes using Linux cgroups. Issues addressed include an out of bounds read vulnerability.

2460a4ff120455c4fb22e6a4569df946a8636e43beb21599764d129ef5f68aadDebian Linux Security Advisory 4367-1 - The Qualys Research Labs discovered multiple vulnerabilities in systemd-journald. Two memory corruption flaws, via attacker-controlled alloca()s (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.

A local attacker could potentially exploit this to cause a denial of service, or execute arbitrary code. 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. Various other issues were also addressed.
