Hello,
(Seen in canl-c-2.1.5)
In lcmaps_type_of_proxy() (sslutils.c) the function uses X509V3_EXT_d2i() to parse an extension and return its internal structure. (pci = X509V3_EXT_d2i(pci_ext) in a couple of places). The internal structure should be freed with a suitable free function after use, but is not.
