libcurl's ASN1 parser code has the GTime2str() function, used for parsing an
ASN.1 Generalized Time field. If given an syntactically incorrect field, the
parser might end up using -1 for the length of the time fraction, leading to
a strlen() getting performed on a pointer to a heap buffer area that is not
(purposely) null terminated.

This flaw most likely leads to a crash, but can also lead to heap contents
getting returned to the application when
CURLINFO_CERTINFO is used.
