CVE-2018-16865

Status Candidate

Overview

An allocation of memory without limits, that could result in the stack clashing with another memory region, was discovered in systemd-journald when many entries are sent to the journal socket. A local attacker, or a remote one if systemd-journal-remote is used, may use this flaw to crash systemd-journald or execute code with journald privileges. Versions through v240 are vulnerable.

Red Hat Security Advisory 2019-0049-01 - 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 heap write and stack overflows.

Debian 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.
