If given an syntactically incorrect field, the\nparser might end up using -1 for the length of the *time fraction*, leading to\na `strlen()` getting performed on a pointer to a heap buffer area that is not\n(purposely) null-terminated.\n\nThis flaw most likely leads to a crash, but can also lead to heap contents\ngetting returned to the application when\n[CURLINFO_CERTINFO](https://curl.se/libcurl/c/CURLINFO_CERTINFO.html) is
