[gnutls-devel] GnuTLS | gnutls_init: Always initialize *session (!1652)

[Read-only notification of GnuTLS library development activities]

Eric Blake commented:


See also issue #1414.

The fix proposed so far is incomplete - gnutls_init() has exit paths where *session is modified to the result of calloc() that has later been passed to gnutls_deinit(), which is a stale pointer.  Since there is code in the wild that DOES call gnutls_deinit() on this stale pointer, that is a double-free.
