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