Synopsis

The remote device is missing a vendor-supplied security patch.

Description

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.(CVE-2019-3815)

Impact

A local attacker may be able to cause excessive resource consumption on the BIG-IP system, potentially leading to a failover event.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K22040951.
