4Subject: [PATCH] journald: set a limit on the number of fields (1k)

6We allocate a iovec entry for each field, so with many short entries,
7our memory usage and processing time can be large, even with a relatively
8small message size. Let's refuse overly long entries.

11https://bugzilla.redhat.com/show_bug.cgi?id=1653861
12
13What from I can see, the problem is not from an alloca, despite what the CVE
14description says, but from the attack multiplication that comes from creating
15many very small iovecs: (void* + size_t) for each three bytes of input message.

4Subject: [PATCH] journal: fix out-of-bounds read CVE-2018-16866
5
6The original code didn't account for the fact that strchr() would match on the
7'\0' character, making it read past the end of the buffer if no non-whitespace
8character was present.
9
10This bug was introduced in commit ec5ff4445cca6a which was first released in
11systemd v221 and later fixed in commit 8595102d3ddde6 which was released in
12v240, so versions in the range [v221, v240) are affected.
13
14Patch backported from systemd-stable at f005e73d3723d62a39be661931fcb6347119b52b
15also includes a change from systemd master which removes a heap buffer overflow
16a6aadf4ae0bae185dc4c414d492a4a781c80ffe5.

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.
