CVE-2019-3823

Priority
Description
libcurl versions from 7.34.0 to before 7.64.0 are vulnerable to a heap
out-of-bounds read in the code handling the end-of-response for SMTP. If
the buffer passed to `smtp_endofresp()` isn't NUL terminated and contains
no character ending the parsed number, and `len` is set to 5, then the
`strtol()` call reads beyond the allocated buffer. The read contents will
not be returned to the caller.
