4Subject: [PATCH] journal: fix syslog_parse_identifier()
5
6Fixes #9829.
7
8An out of bounds read was discovered in systemd-journald in the way it
9parses log messages that terminate with a colon ':'. A local attacker
10can use this flaw to disclose process memory data.
11
12Patch backported from systemd master at
13a6aadf4ae0bae185dc4c414d492a4a781c80ffe5.
14
15This matches the change done for systemd-journald, hence forming the first
16part of the fix for CVE-2018-16866.
