CVE-2019-3815· NVD / CVE Program· CNA redhat

A memory leak was discovered in the backport of fixes for CVE-2018-16864 in Red Hat Enterprise Linux.

Noroxi assessment

Priority: Monitor (action score 13/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.40% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: systemd (Debian:8) 215-17+deb8u11; libgudev1 (Red Hat:enterprise_linux:7::client) 0:219-62.el7_6.3; libgudev1-devel (Red Hat:enterprise_linux:7::client) 0:219-62.el7_6.3.

Low priority for now. Upgrade to systemd (Debian:8) 215-17+deb8u11; libgudev1 (Red Hat:enterprise_linux:7::client) 0:219-62.el7_6.3; libgudev1-devel (Red Hat:enterprise_linux:7::client) 0:219-62.el7_6.3 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

A memory leak was discovered in the backport of fixes for CVE-2018-16864 in Red Hat Enterprise Linux. Function dispatch_message_real() in journald-server.c does not free the memory allocated by set_iovec_field_free() to store the `_CMDLINE=` entry. A local attacker may use this flaw to make systemd-journald crash. This issue only affects versions shipped with Red Hat Enterprise since v219-62.2.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
