basic/ellipsize: do not assume the string is NUL-terminated when length is given oss-fuzz flags this as: ==1==WARNING: MemorySanitizer: use-of-uninitialized-value 0. 0x7fce77519ca5 in ascii_is_valid systemd/src/basic/utf8.c:252:9 1. 0x7fce774d203c in ellipsize_mem systemd/src/basic/string-util.c:544:13 2. 0x7fce7730a299 in print_multiline systemd/src/shared/logs-show.c:244:37 3. 0x7fce772ffdf3 in output_short systemd/src/shared/logs-show.c:495:25 4. 0x7fce772f5a27 in show_journal_entry systemd/src/shared/logs-show.c:1077:15 5. 0x7fce772f66ad in show_journal systemd/src/shared/logs-show.c:1164:29 6. 0x4a2fa0 in LLVMFuzzerTestOneInput systemd/src/fuzz/fuzz-journal-remote.c:64:21 ... I didn't reproduce the issue, but this looks like an obvious error: the length is specified, so we shouldn't use the string with any functions for normal C-strings.
