Debian DLA-1639-1 : systemd security update

high Nessus Plugin ID 121316

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Multiple vulnerabilities were found in the journald component of systemd which can lead to a crash or code execution.

CVE-2018-16864

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.

CVE-2018-16865

An allocation of memory without limits, that could result in the stack clashing with another memory region, was discovered in systemd-journald when a program with long command line arguments calls syslog. A local attacker may use this flaw to crash systemd-journald or escalate his privileges. Versions through v240 are vulnerable.

For Debian 8 'Jessie', these problems have been fixed in version 215-17+deb8u9.

We recommend that you upgrade your systemd packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
